Modern Christianity is widely diverse in its social structures, beliefs and practices, but this diversity is mild compared to the first three centuries A.D., when Christians disagreed on such basic issues as how many gods there were, or whether Jesus was human, divine, both, or neither.
This begins by considering key terms used in the course, such as orthodoxy and heresy, followed by an introduction to the Ebionites, who maintained Jewish practices while believing that Jesus was the messiah.
This lecture examines the Marcionites, a group of heretics diametrically opposed to the Ebionites. Using the apostle Paul as his source, their leader, Marcion, insisted that true Christianity had nothing to do with Judaism.
The Gnostics believed that special knowledge brought salvation to souls trapped in the evil, material world. Before 1945 and the discovery of the Nag Hammadi library, information about this widespread group of Christian sects came almost solely from the writings of Irenaeus, Tertullian, and other church fathers who opposed them.
This lecture provides an overview of the Gnostic religions. It considers their possible origins within a Judeo-Christian tradition that maintained that God had created the world and controlled it. This was hard for some Jews and/or Christians to accept.
One of the most intriguing documents from the Nag Hammadi library is the Gnostic Gospel of Truth. It does not relate stories about the life of Jesus, but instead celebrates the "good news" that Jesus brought. The views of God, the world, Christ, and salvation here stand in stark contrast with those that became orthodox within Christianity.
This lecture considers two writings that attempted to explain the Gnostic system to outsiders. Ptolemy tries to show that neither the one true God nor the Devil could have inspired the Old Testament. In the Treatise on the Resurrection, the anonymous author insists that, contrary to the claims of proto-orthodox Christians, the resurrection is of the spirit, not the flesh.
The Gospel of Thomas is the most significant Nag Hammadi document. It consists of 114 sayings attributed to Jesus, with no reference to his miracles, death, or resurrection.
Understanding the Gnostic story can help explain the teachings in the Coptic Gospel of Thomas. Rather than the savior who dies for the sins of the world, Jesus is portrayed as the divine teacher who reveals the truth necessary for salvation.
The Gospels of the New Testament say very little about Jesus' life as an infant and young boy. This "lost period" is the subject of several early Gospels, however, including the Proto-Gospel of James, and the Infancy Gospel of Thomas.
A fragment is all that remains of the Gospel allegedly written by Jesus' disciple Peter. Early writings proclaim it a forgery. This description of Jesus' trial, crucifixion, and resurrection is both similar to, and strikingly different from, canonical accounts.
In 1958 at the Mar Saba library near Jerusalem, scholar Morton Smith found a fragment of a letter supposedly written by the 2nd-century church father Clement. It indicated that a second edition of Mark's Gospel existed, and was intended only for the spiritually elite. Is this letter authentic or a modern forgery?
To some extent, the noncanonical Acts are modeled on the Book of Acts in the New Testament. They differ, however, in that each is about only one of the major apostles in early Christendom: John, Peter, Paul, Andrew, and Thomas.
The Apocryphal Acts resembled the ancient romances (novels). While the Christian Acts use many of these conventions, their goal is to counteract the views that the romances embraced.
One of the most popular apocryphal accounts from Christian antiquity involved the conversion and exploits of Thecla of Asia Minor, an aristocratic woman who converts to the Christian faith through the preaching of Paul.
A number of letters survive that are credited to the apostle Paul, but which were clearly fabricated. This lecture considers two sets of such correspondence. Evidently forged in the fourth century, these letters were meant to portray Paul as equal to the greatest minds of his day.
The Epistle of Barnabas is not considered forged. Although later attributed to Paul's traveling companion Barnabas, it is actually anonymous. This is one of the most virulently anti-Jewish treatises of Christian antiquity.
This lecture examines an Apocalypse of Peter completely unrelated to the one previously discussed. This is a proto-orthodox composition that represents the first surviving narrative of a guided tour of heaven and hell, a forerunner of Dante's Divine Comedy.
The standard definition of orthodoxy was proffered by the 4th-century church father Eusebius. He maintained that orthodoxy was the view taught by Jesus and his apostles.
Christianity was unique among religions of the Greco-Roman world in emphasizing the importance of belief instead of cultic practice, and in its insistence that it was the only true religion. The formation of the New Testament canon can be seen as a development among Christians to root their beliefs in the teachings of Jesus and his apostles.
Contrary to popular belief, the canon of the New Testament's 27 books did not emerge at the very beginning of the Christian movement. Although written during the 1st century, or soon thereafter, it took 300 years before these books were declared to be canonical.
Deciding which books to include in the canon was not enough to ensure the proto-orthodox understanding of the Christian faith. There were numerous ways to interpret the books of Scripture, and the early Christian centuries saw numerous debates over interpretation.
Of the nearly 5,400 copies of New Testament writings that survive today (in the original Greek), no two are exactly alike. All of the available texts were copied by hand. Some of the discrepancies appear to have been intentional.
The final lecture considers the formation of the Christian creeds: statements of faith to determine what was true (orthodox) and what was false (heretical). The well-known creeds of the 4th century, such as the Nicene Creed, developed from earlier formulations known as the "Rule of Faith," and from confessions by converts before baptism.
