Wilfrid was an English bishop and saint. Born a Northumbrian noble, he entered religious life as a teenager and studied at Lindisfarne, at Canterbury, in Francia, and at Rome; he returned to Northumbria in about 660, and became the abbot of a newly founded monastery at Ripon. In 664 Wilfrid acted as spokesman for the Roman position at the Synod of Whitby, and became famous for his speech advocating that the Roman method for calculating the date of Easter should be adopted. His success prompted the king's son, Alhfrith, to appoint him Bishop of Northumbria. Wilfrid chose to be consecrated in Gaul because of the lack of what he considered to be validly consecrated bishops in England at that time. During Wilfrid's absence Alhfrith seems to have led an unsuccessful revolt against his father, Oswiu, leaving a question mark over Wilfrid's appointment as bishop. Before Wilfrid's return Oswiu had appointed Ceadda in his place, resulting in Wilfrid's retirement to Ripon for a few years following his arrival back in Northumbria.

Theodore of Tarsus was Archbishop of Canterbury from 668 to 690. Theodore grew up in Tarsus, but fled to Constantinople after the Persian Empire conquered Tarsus and other cities. After studying there, he relocated to Rome and was later installed as the Archbishop of Canterbury on the orders of Pope Vitalian. Accounts of his life appear in two 8th-century texts. Theodore is best known for his reform of the English Church and establishment of a school in Canterbury.
