Saint Peter known as Simon Peter, Simon, or Cephas, according to the New Testament, was one of the Twelve Apostles of Jesus Christ, leaders of the early Christian Great Church. Pope Gregory I called him the "Prince of the Apostles". According to Catholic teaching, Jesus promised Peter in the "Rock of My Church" dialogue in Matthew 16:18 a special position in the Church, he is traditionally counted as the first Bishop of Rome—or pope—and by Eastern Christian tradition as the first Patriarch of Antioch. The ancient Christian churches all venerate Peter as a major saint and as the founder of the Church of Antioch and the Roman Church, but differ in their attitudes regarding the authority of his present-day successors; the New Testament indicates that Peter's father's name was John and was from the village of Bethsaida in the province of Galilee or Gaulanitis. His brother Andrew was an apostle. According to New Testament accounts, Peter was one of twelve apostles chosen by Jesus from his first disciples.
A fisherman, he played a leadership role and was with Jesus during events witnessed by only a few apostles, such as the Transfiguration. According to the gospels, Peter confessed Jesus as the Messiah, was part of Jesus's inner circle, thrice denied Jesus and wept bitterly once he realised his deed, preached on the day of Pentecost. According to Christian tradition, Peter was crucified in Rome under Emperor Nero, it is traditionally held that he was crucified upside down at his own request, since he saw himself unworthy to be crucified in the same way as Jesus. Tradition holds, his remains are said to be those contained in the underground Confessio of St. Peter's Basilica, where Pope Paul VI announced in 1968 the excavated discovery of a first-century Roman cemetery; every 29 June since 1736, a statue of Saint Peter in St. Peter's Basilica is adorned with papal tiara, ring of the fisherman, papal vestments, as part of the celebration of the Feast of Saints Peter and Paul. According to Catholic doctrine, the direct papal successor to Saint Peter is the incumbent pope Pope Francis.
Two general epistles in the New Testament are ascribed to Peter, but modern scholars reject the Petrine authorship of both. The Gospel of Mark was traditionally thought to show the influence of Peter's preaching and eyewitness memories. Several other books bearing his name—the Acts of Peter, Gospel of Peter, Preaching of Peter, Apocalypse of Peter, Judgment of Peter—are considered by Christian denominations as apocryphal, are thus not included in their Bible canons. Peter's original name, as indicated in the New Testament, was "Simon" or "Simeon"; the Simon/Simeon variation has been explained as reflecting "the well-known custom among Jews at the time of giving the name of a famous patriarch or personage of the Old Testament to a male child along with a similar sounding Greek/Roman name". He was given the name כֵּיפָא in Aramaic, rendered in Greek as Κηφᾶς, whence Latin and English Cephas; the precise meaning of the Aramaic word is disputed, some saying that its usual meaning is "rock" or "crag", others saying that it means rather "stone" and in its application by Jesus to Simon, "precious stone" or "jewel", but most scholars agree that as a proper name it denotes a rough or tough character.
Both meanings, "stone" and "rock", are indicated in dictionaries of Syriac. Catholic theologian Rudolf Pesch argues that the Aramaic cepha means "stone, clump, clew" and that "rock" is only a connotation; the combined name Σίμων Πέτρος appears 19 times in the New Testament. In some Syriac documents he is called, in Simon Cephas. Peter's life story is told in the four canonical gospels, the Acts of the Apostles, New Testament letters, the non-canonical Gospel of the Hebrews and other Early Church accounts of his life and death. In the New Testament, he is among the first of the disciples called during Jesus' ministry. Peter became the first listed apostle ordained by Jesus in the early church. Peter was a fisherman in Bethsaida, he was named son of Jonah or John. The three Synoptic Gospels recount how Peter's mother-in-law was healed by Jesus at their home in Capernaum. 1 Cor. 9:5 has been taken to imply that he was married. In the Synoptic Gospels, Peter was a fisherman along with his brother and the sons of Zebedee and John.
The Gospel of John depicts Peter fishing after the resurrection of Jesus, in the story of the Catch of 153 fish. In Matthew and Mark, Jesus called Simon and his brother Andrew to be "fishers of men". A Franciscan church is built upon the traditional site of Apostle Peter's house. In Luke, Simon Peter owns the boat that Jesus uses to preach to the multitudes who were pressing on him at the shore of Lake Gennesaret. Jesu

Excommunication is an institutional act of religious censure used to deprive, suspend, or limit membership in a religious community or to restrict certain rights within it, in particular receiving of the sacraments. The term is historically used to refer to excommunications from the Catholic Church, but it is used more to refer to similar types of institutional religious exclusionary practices and shunning among other religious groups. For instance, many Protestant denominations, such as the Lutheran Churches, have similar practices of excusing congregants from church communities, while Jehovah's Witnesses, as well as the Churches of Christ, use the term "disfellowship" to refer to their form of excommunication; the Amish have been known to excommunicate members that were either seen or known for breaking rules, or questioning the church. The word excommunication means putting a specific group out of communion. In some denominations, excommunication includes spiritual condemnation of the group.
Excommunication may involve banishment and shaming, depending on the group, the offense that caused excommunication, or the rules or norms of the religious community. The grave act is revoked in response to sincere penance, which may be manifested through public recantation, sometimes through the Sacrament of Confession, piety or through mortification of the flesh. Within the Catholic Church, there are differences between the discipline of the majority Latin Church regarding excommunication and that of the Eastern Catholic Churches. In Latin Catholic canon law, excommunication is a applied censure and thus a "medicinal penalty" intended to invite the person to change behaviour or attitude and return to full communion, it is not an "expiatory penalty" designed to make satisfaction for the wrong done, much less a "vindictive penalty" designed to punish: "excommunication, the gravest penalty of all and the most frequent, is always medicinal", is "not at all vindictive". Excommunication can be either latae ferendae sententiae.
According to Bishop Thomas J. Paprocki, "excommunication does not expel the person from the Catholic Church, but forbids the excommunicated person from engaging in certain activities..." These activities are listed in Canon 1331 §1, prohibit the individual from any ministerial participation in celebrating the sacrifice of the Eucharist or any other ceremonies of worship. Under current Catholic canon law, excommunicates remain bound by ecclesiastical obligations such as attending Mass though they are barred from receiving the Eucharist and from taking an active part in the liturgy. "Excommunicates lose rights, such as the right to the sacraments, but they are still bound to the obligations of the law. They are urged to retain a relationship with the Church, as the goal is to encourage them to repent and return to active participation in its life; these are the only effects for those. For instance, a priest may not refuse Communion publicly to those who are under an automatic excommunication, as long as it has not been declared to have been incurred by them if the priest knows that they have incurred it.
On the other hand, if the priest knows that excommunication has been imposed on someone or that an automatic excommunication has been declared, he is forbidden to administer Holy Communion to that person.. In the Catholic Church, excommunication is resolved by a declaration of repentance, profession of the Creed and an Act of Faith, or renewal of obedience by the excommunicated person and the lifting of the censure by a priest or bishop empowered to do this. "The absolution can be in the internal forum only, or in the external forum, depending on whether scandal would be given if a person were absolved and yet publicly considered unrepentant." Since excommunication excludes from reception of the sacraments, absolution from excommunication is required before absolution can be given from the sin that led to the censure. In many cases, the whole process takes place on a single occasion in the privacy of the confessional. For some more serious wrongdoings, absolution from excommunication is reserved to a bishop, another ordinary, or the Pope.
These can delegate a priest to act on their behalf. Interdict is a censure similar to excommunication, it too excludes from ministerial functions in public worship and from reception of the sacraments, but not from the exercise of governance. In the Eastern Catholic Churches, excommunications is imposed only by decree, never incurred automatically by latae sententiae excommunication. A distinction is made between major excommunication; those on whom minor excommunication has been imposed are excluded from receiving the Eucharist and can be excluded from participating in the Divine Liturgy. They can be excluded from entering a church when divine worship is being celebrated there; the decree of excommunication must indicate the precise effect of the excommunication and, if required, its duration.

Constantinople was the capital city of the Roman Empire, of the Byzantine Empire, of the brief Crusader state known as the Latin Empire, until falling to the Ottoman Empire. It was reinaugurated in 324 from ancient Byzantium as the new capital of the Roman Empire by Emperor Constantine the Great, after whom it was named, dedicated on 11 May 330; the city was located in what is now the core of modern Istanbul. From the mid-5th century to the early 13th century, Constantinople was the largest and wealthiest city in Europe; the city was famed for its architectural masterpieces, such as the Greek Orthodox cathedral of Hagia Sophia, which served as the seat of the Ecumenical Patriarchate, the sacred Imperial Palace where the Emperors lived, the Galata Tower, the Hippodrome, the Golden Gate of the Land Walls, the opulent aristocratic palaces lining the arcaded avenues and squares. The University of Constantinople was founded in the fifth century and contained numerous artistic and literary treasures before it was sacked in 1204 and 1453, including its vast Imperial Library which contained the remnants of the Library of Alexandria and had over 100,000 volumes of ancient texts.
It was instrumental in the advancement of Christianity during Roman and Byzantine times as the home of the Ecumenical Patriarch of Constantinople and as the guardian of Christendom's holiest relics such as the Crown of Thorns and the True Cross. Constantinople was famed for its complex defences; the first wall of the city was erected by Constantine I, surrounded the city on both land and sea fronts. In the 5th century, the Praetorian Prefect Anthemius under the child emperor Theodosius II undertook the construction of the Theodosian Walls, which consisted of a double wall lying about 2 kilometres to the west of the first wall and a moat with palisades in front; this formidable complex of defences was one of the most sophisticated of Antiquity. The city was built intentionally to rival Rome, it was claimed that several elevations within its walls matched the'seven hills' of Rome; because it was located between the Golden Horn and the Sea of Marmara the land area that needed defensive walls was reduced, this helped it to present an impregnable fortress enclosing magnificent palaces and towers, the result of the prosperity it achieved from being the gateway between two continents and two seas.
Although besieged on numerous occasions by various armies, the defences of Constantinople proved impregnable for nearly nine hundred years. In 1204, the armies of the Fourth Crusade took and devastated the city, its inhabitants lived several decades under Latin misrule. In 1261 the Byzantine Emperor Michael VIII Palaiologos liberated the city, after the restoration under the Palaiologos dynasty, enjoyed a partial recovery. With the advent of the Ottoman Empire in 1299, the Byzantine Empire began to lose territories and the city began to lose population. By the early 15th century, the Byzantine Empire was reduced to just Constantinople and its environs, along with Morea in Greece, making it an enclave inside the Ottoman Empire. According to Pliny the Elder in his Natural History, the first known name of a settlement on the site of Constantinople was Lygos, a settlement of Thracian origin founded between the 13th and 11th centuries BC; the site, according to the founding myth of the city, was abandoned by the time Greek settlers from the city-state of Megara founded Byzantium in around 657 BC, across from the town of Chalcedon on the Asiatic side of the Bosphorus.
The origins of the name of Byzantion, more known by the Latin Byzantium, are not clear, though some suggest it is of Thraco-Illyrian origin. The founding myth of the city has it told that the settlement was named after the leader of the Megarian colonists, Byzas; the Byzantines of Constantinople themselves would maintain that the city was named in honour of two men and Antes, though this was more just a play on the word Byzantion. The city was renamed Augusta Antonina in the early 3rd century AD by the Emperor Septimius Severus, who razed the city to the ground in 196 for supporting a rival contender in the civil war and had it rebuilt in honour of his son Marcus Aurelius Antoninus, popularly known as Caracalla; the name appears to have been forgotten and abandoned, the city reverted to Byzantium/Byzantion after either the assassination of Caracalla in 217 or, at the latest, the fall of the Severan dynasty in 235. Byzantium took on the name of Kōnstantinoupolis after its refoundation under Roman emperor Constantine I, who transferred the capital of the Roman Empire to Byzantium in 330 and designated his new capital as Nova Roma'New Rome'.
During this time, the city was called'Second Rome','Eastern Rome', Roma Constantinopolitana. As the city became the sole remaining capital of the Roman Empire after the fall of the West, its wealth and influence grew, the city came to have a multitude of nicknames; as the largest and wealthiest city in Europe during the 4th–13th centuries and a centre of culture and education of the Mediterranean basin, Constantinople came to be known by prestigious titles such as Basileuousa and Megalopol
Heraclius was the Emperor of the Byzantine Empire from 610 to 641. He was responsible for introducing Greek as the Byzantine Empire's official language, his rise to power began in 608, when he and his father, Heraclius the Elder, the exarch of Africa, led a revolt against the unpopular usurper Phocas. Heraclius's reign was marked by several military campaigns; the year Heraclius came to power, the empire was threatened on multiple frontiers. Heraclius took charge of the Byzantine–Sasanian War of 602–628; the first battles of the campaign ended in defeat for the Byzantines. Soon after, he initiated reforms to strengthen the military. Heraclius drove the Persians out of Asia Minor and pushed deep into their territory, defeating them decisively in 627 at the Battle of Nineveh; the Persian king Khosrow II was overthrown and executed by his son Kavadh II, who soon sued for a peace treaty, agreeing to withdraw from all occupied territory. This way peaceful relations were restored to the two strained empires.
Heraclius soon experienced the Muslim conquests. Emerging from the Arabian Peninsula, the Muslims conquered the Sasanian Empire. In 634 the Muslims marched into Roman Syria. Within a short period of time, the Arabs conquered Mesopotamia and Egypt. Heraclius entered diplomatic relations with the Serbs in the Balkans, he tried to repair the schism in the Christian church in regard to the Monophysites, by promoting a compromise doctrine called Monothelitism. The Church of the East was involved in the process; this project of unity was rejected by all sides of the dispute. Heraclius was the eldest son of Heraclius the Elder and Epiphania, of a family of possible Armenian origin from Cappadocia, with speculative Arsacid descent. Beyond that, there is little specific information known about his ancestry, his father was a key general during Emperor Maurice's war with Bahram Chobin, usurper of the Sasanian Empire, during 590. After the war, Maurice appointed Heraclius the Elder to the position of Exarch of Africa.
In 608, Heraclius the Elder renounced his loyalty to the Emperor Phocas, who had overthrown Maurice six years earlier. The rebels issued coins showing both Heraclii dressed as consuls, though neither of them explicitly claimed the imperial title at this time. Heraclius's younger cousin Nicetas launched an overland invasion of Egypt. Meanwhile, the younger Heraclius sailed eastward with another force via Cyprus; as he approached Constantinople, he made contact with prominent leaders and planned an attack to overthrow aristocrats in the city, soon arranged a ceremony where he was crowned and acclaimed as Emperor. When he reached the capital, the Excubitors, an elite Imperial Guard unit led by Phocas's son-in-law Priscus, deserted to Heraclius, he entered the city without serious resistance; when Heraclius captured Phocas, he asked him "Is this how you have ruled, wretch?" Phocas's reply—"And will you rule better?"—so enraged Heraclius that he beheaded Phocas on the spot. He had the genitalia removed from the body because Phocas had raped the wife of Photius, a powerful politician in the city.
On October 5, 610, Heraclius was crowned for a second time, this time in the Chapel of St. Stephen within the Great Palace. After her death in 612, he married his niece Martina in 613. In the reign of Heraclius's two sons, the divisive Martina was to become the center of power and political intrigue. Despite widespread hatred for Martina in Constantinople, Heraclius took her on campaigns with him and refused attempts by Patriarch Sergius to prevent and dissolve the marriage. During his Balkan Campaigns, Emperor Maurice and his family were murdered by Phocas in November 602 after a mutiny. Khosrau II of the Sasanian Empire had been restored to his throne by Maurice, they had remained allies until the latter's death. Thereafter, Khosrau seized the opportunity to attack the Byzantine reconquer Mesopotamia. Khosrau had at his court a man who claimed to be Maurice's son Theodosius, Khosrau demanded that the Byzantines accept this Theodosius as Emperor; the war went the Persians' way because of Phocas's brutal repression and the succession crisis that ensued as the general Heraclius sent his nephew Nicetas to attack Egypt, enabling his son Heraclius the younger to claim the throne in 610.
Phocas, an unpopular ruler, invariably described in historical sources as a "tyrant", was deposed by Heraclius, who sailed to Constantinople from Carthage with an icon affixed to the prow of his ship. By this time, the Persians had conquered Mesopotamia and the Caucasus, in 611 they overran Syria and entered Anatolia. A major counter-attack led by Heraclius two years was decisively defeated outside Antioch by Shahrbaraz and Shahin, the Roman position collapsed. Over the following decade the Persians were able to conquer Palestine and Egypt and to devastate Anatolia, while the Avars and Slavs took advantage of the situation to overrun th
Encyclopædia Britannica, Eleventh Edition
The Encyclopædia Britannica, Eleventh Edition is a 29-volume reference work, an edition of the Encyclopædia Britannica. It was developed during the encyclopaedia's transition from a British to an American publication; some of its articles were written by the best-known scholars of the time. This edition of the encyclopedia, containing 40,000 entries, is now in the public domain, many of its articles have been used as a basis for articles in Wikipedia. However, the outdated nature of some of its content makes its use as a source for modern scholarship problematic; some articles have special value and interest to modern scholars as cultural artifacts of the 19th and early 20th centuries. The 1911 eleventh edition was assembled with the management of American publisher Horace Everett Hooper. Hugh Chisholm, who had edited the previous edition, was appointed editor in chief, with Walter Alison Phillips as his principal assistant editor. Hooper bought the rights to the 25-volume 9th edition and persuaded the British newspaper The Times to issue its reprint, with eleven additional volumes as the tenth edition, published in 1902.
Hooper's association with The Times ceased in 1909, he negotiated with the Cambridge University Press to publish the 29-volume eleventh edition. Though it is perceived as a quintessentially British work, the eleventh edition had substantial American influences, not only in the increased amount of American and Canadian content, but in the efforts made to make it more popular. American marketing methods assisted sales; some 14% of the contributors were from North America, a New York office was established to coordinate their work. The initials of the encyclopedia's contributors appear at the end of selected articles or at the end of a section in the case of longer articles, such as that on China, a key is given in each volume to these initials; some articles were written by the best-known scholars of the time, such as Edmund Gosse, J. B. Bury, Algernon Charles Swinburne, John Muir, Peter Kropotkin, T. H. Huxley, James Hopwood Jeans and William Michael Rossetti. Among the lesser-known contributors were some who would become distinguished, such as Ernest Rutherford and Bertrand Russell.
Many articles were carried over from some with minimal updating. Some of the book-length articles were divided into smaller parts for easier reference, yet others much abridged; the best-known authors contributed only a single article or part of an article. Most of the work was done by British Museum scholars and other scholars; the 1911 edition was the first edition of the encyclopædia to include more than just a handful of female contributors, with 34 women contributing articles to the edition. The eleventh edition introduced a number of changes of the format of the Britannica, it was the first to be published complete, instead of the previous method of volumes being released as they were ready. The print type was subject to continual updating until publication, it was the first edition of Britannica to be issued with a comprehensive index volume in, added a categorical index, where like topics were listed. It was the first not to include long treatise-length articles. Though the overall length of the work was about the same as that of its predecessor, the number of articles had increased from 17,000 to 40,000.
It was the first edition of Britannica to include biographies of living people. Sixteen maps of the famous 9th edition of Stielers Handatlas were translated to English, converted to Imperial units, printed in Gotha, Germany by Justus Perthes and became part this edition. Editions only included Perthes' great maps as low quality reproductions. According to Coleman and Simmons, the content of the encyclopedia was distributed as follows: Hooper sold the rights to Sears Roebuck of Chicago in 1920, completing the Britannica's transition to becoming a American publication. In 1922, an additional three volumes, were published, covering the events of the intervening years, including World War I. These, together with a reprint of the eleventh edition, formed the twelfth edition of the work. A similar thirteenth edition, consisting of three volumes plus a reprint of the twelfth edition, was published in 1926, so the twelfth and thirteenth editions were related to the eleventh edition and shared much of the same content.
However, it became apparent that a more thorough update of the work was required. The fourteenth edition, published in 1929, was revised, with much text eliminated or abridged to make room for new topics; the eleventh edition was the basis of every version of the Encyclopædia Britannica until the new fifteenth edition was published in 1974, using modern information presentation. The eleventh edition's articles are still of value and interest to modern readers and scholars as a cultural artifact: the British Empire was at its maximum, imperialism was unchallenged, much of the world was still ruled by monarchs, the tragedy of the modern world wars was still in the future, they are an invaluable resource for topics omitted from modern encyclopedias for biography and the history of science and technology. As a literary text, the encyclopedia has value as an example of early 20th-century prose. For example, it employs literary devices, such as pathetic fallacy, which are not as common in modern reference texts.
In 1917, using the pseudonym of S. S. Van Dine, the US art critic and author Willard Huntington Wright published Misinforming a Nation, a 200+
The Liber Pontificalis is a book of biographies of popes from Saint Peter until the 15th century. The original publication of the Liber Pontificalis stopped with Pope Adrian II or Pope Stephen V, but it was supplemented in a different style until Pope Eugene IV and Pope Pius II. Although quoted uncritically from the 8th to 18th century, the Liber Pontificalis has undergone intense modern scholarly scrutiny; the work of the French priest Louis Duchesne, of others has highlighted some of the underlying redactional motivations of different sections, though such interests are so disparate and varied as to render improbable one popularizer's claim that it is an "unofficial instrument of pontifical propaganda."The title Liber Pontificalis goes back to the 12th century, although it only became current in the 15th century, the canonical title of the work since the edition of Duchesne in the 19th century. In the earliest extant manuscripts it is referred to as Liber episcopalis in quo continentur acta beatorum pontificum Urbis Romae and the Gesta or Chronica pontificum.
During the Middle Ages, Saint Jerome was considered the author of all the biographies up until those of Pope Damasus I, based on an apocryphal letter between Saint Jerome and Pope Damasus published as a preface to the Medieval manuscripts. The attribution originated with Rabanus Maurus and is repeated by Martin of Opava, who extended the work into the 13th century. Other sources attribute the early work to Hegesippus and Irenaeus, having been continued by Eusebius of Caesarea. In the 16th century, Onofrio Panvinio attributed the biographies after Damasus until Pope Nicholas I to Anastasius Bibliothecarius; the modern interpretation, following that of Louis Duchesne, is that the Liber Pontificalis was and unsystematically compiled, that the authorship is impossible to determine, with a few exceptions. Duchesne and others have viewed the beginning of the Liber Pontificalis up until the biographies of Pope Felix III as the work of a single author, a contemporary of Pope Anastasius II, relying on Catalogus Liberianus, which in turn draws from the papal catalogue of Hippolytus of Rome, the Leonine Catalogue, no longer extant.
Most scholars believe the Liber Pontificalis was first compiled in the 6th century. Because of the use of the vestiarium, the records of the papal treasury, some have hypothesized that the author of the early Liber Pontificalis was a clerk of the papal treasury. Edward Gibbon's Decline and Fall of the Roman Empire summarised the scholarly consensus as being that the Liber Pontificalis was composed by "apostolic librarians and notaries of the viiith and ixth centuries" with only the most recent portion being composed by Anastasius. Duchesne and others believe that the author of the first addition to the Liber Pontificalis was a contemporary of Pope Silverius, that the author of another addition was a contemporary of Pope Conon, with popes being added individually and during their reigns or shortly after their deaths; the Liber Pontificalis only contained the names of the bishops of Rome and the durations of their pontificates. As enlarged in the 6th century, each biography consists of: the birth name of the pope and that of his father, place of birth, profession before elevation, length of pontificate, historical notes of varying thoroughness, major theological pronouncements and decrees, administrative milestones, date of death, place of burial, the duration of the ensuing sede vacante.
Pope Adrian II is the last pope for which there are extant manuscripts of the original Liber Pontificalis: the biographies of Pope John VIII, Pope Marinus I, Pope Adrian III are missing and the biography of Pope Stephen V is incomplete. From Stephen V through the 10th and 11th centuries, the historical notes are abbreviated with only the pope's origin and reign duration, it was only in the 12th century that the Liber Pontificalis was systematically continued, although papal biographies exist in the interim period in other sources. Duchesne refers to the 12th century work by Petrus Guillermi in 1142 at the monastery of St. Gilles as the Liber Pontificalis of Petrus Guillermi. Guillermi's version is copied from other works with small additions or excisions from the papal biographies of Pandulf, nephew of Hugo of Alatri, which in turn was copied verbatim from the original Liber Pontificalis from other sources until Pope Honorius II, with contemporary information from Pope Paschal II to Pope Urban II.
Duchesne attributes all biographies from Pope Gregory VII to Urban II to Pandulf, while earlier historians like Giesebrecht and Watterich attributed the biographies of Gregory VII, Victor III, Urban II to Petrus Pisanus, the subsequent biographies to Pandulf. These biographies until those of Pope Martin IV are extant only as revised by Petrus Guillermi in the manuscripts of the monastery of
