The quest for the historical Jesus consists of academic efforts to determine what words and actions, if any, may be attributed to Jesus, and to use the findings to provide portraits of the historical Jesus. Since the 18th century, three scholarly quests for the historical Jesus have taken place, each with distinct characteristics and based on different research criteria, which were often developed during each specific phase. These quests are distinguished from earlier approaches because they rely on the historical method to study biblical narratives. While textual analysis of biblical sources had taken place for centuries, these quests introduced new methods and specific techniques to establish the historical validity of their conclusions.

Jesus, also referred to as Jesus Christ, Jesus of Nazareth, and many other names and titles, was a first-century Jewish preacher and religious leader. He is the central figure of Christianity, the world's largest religion. Most Christians believe Jesus to be the incarnation of God the Son and the awaited messiah, the Christ that is prophesied in the Old Testament.
