From Jesus to Constantine: A History of Early Christianity
Course Overview
Uncover the riveting story of the early formation of the Christian religion and learn how this faith grew from 20 followers to 2 billion.
Did the ancient Jews of Jesus’ time always believe in a single, all-powerful God? How did breaking away from their Jewish roots make Christians more vulnerable in the Roman world? What were the origins of what we now consider the distinctively Christian liturgical practices of baptism and the Eucharist?
As these 24 lectures show, the answers are quite surprising. Professor Ehrman takes you back to Christianity’s first three centuries to explain its transition from the religion of Jesus to a religion about Jesus. He introduces you to lost Christianities and their sacred writings, many of which were originally proscribed or destroyed, only to be rediscovered in modern times.
You’ll learn how a single group from among many won the struggle for dominance, which allowed it to establish the central beliefs of the faith, rewrite the history of Christianity’s internal conflicts, and produce a canon of sacred texts (the New Testament) that supported its own views. Additionally, you’ll examine Christianity’s beginnings, Jewish-Christian relations, hostility to the Christian mission, and internal struggles within the faith.
These lectures provide an engaging experience that will enhance your understanding of Christianity today, offering a scholar’s perspective on the origins of what Professor Ehrman describes as the most important institution in Western civilization.
