Not all of Paul's letters were composed by the apostle himself. The three "Deutero-Pauline" letters (2 Thessalonians, Colossians, and Ephesians) likely date to the years after Paul's death. In content, they seek to reassure readers that a series of events must occur before the end times arrive and that faith in Christ is all that is necessary for salvation in the present.

The gospel writers recorded much of Jesus' life, but they also acknowledged that they didn't record everything. Much of what he said is recorded in so-called "dialogic gospels," accounts of Jesus in lengthy conversations with one or more of his disciples. Study three of these unique works and gain new theological insight into Christianity.

Continue your study of Paul's epistles with a detailed look at his letter to the Galatians. In it, he offers a scathing rebuke to a congregation he believes has backslid after his departure. Find out why he believed it was so important to establish faith in Jesus as the one and only quality that gets you into heaven.

Begin by exploring the key tenets of the religious movements of ancient Gnosticism, centered in the concept of gnosis, or direct, personal knowledge of God. Learn about the exciting 1945 discovery of the Nag Hammadi codices, a large cache of ancient manuscripts representing four diverse Gnostic traditions.

What happened when an early Christian community began to fall apart? Disagreements over theology, challenges to church leadership, or disintegration of the group altogether were common, and the letters of John tackle these problems head-on. Delve into early efforts to unify a fractured church.

Along with James and the three letters of John, 1-2 Peter and Jude are known as the "catholic" or general epistles because they are addressed to multiple congregations, or Christians, in general. See what these most recent books of the New Testament tell us about a mature and growing religious movement.

The New Testament tells us Jesus rose from the dead and appeared to the apostles before ascending into heaven. While the canonical gospels left Jesus' words a mystery, many apocryphal writers filled in the gaps. Examine several of these dialogic gospels to learn what Jesus told his followers after the resurrection.

Historians have often depicted the religious movement of Manichaeism as the culmination of ancient Gnosticism. Investigate Manichaeism's extraordinarily complex mythology - envisioning reality as a struggle between cosmic forces of Light and Darkness - its conception of salvation, and the structural hierarchy through which Manichaeism became a highly organized international religion.

The Gnostic texts The Revelation of Adam and The Reality of the Rulers rewrite the early chapters of Genesis. Examine how the texts reformulate the story of the Creation, Noah and the Flood, and the question of who will be saved, placing the Gnostics themselves within Genesis and linking the stories to their salvation.

Many of the apocryphal gospels were essentially novels written during the early Christian era, and they were filled with adventurous tales of shipwrecks, necrophilia, self-mutilation, and other wild stories. Dive into the Acts of John to consider this fascinating genre of literature and what it offered audiences of the time - as well as historians today.
