Christianity in the 1st century deals with the formative years of the Early Christian community. The earliest followers of Jesus composed an apocalyptic Jewish sect, which historians refer to as Jewish Christianity. The Apostles dispersed from Jerusalem, founding the Apostolic Sees, presumably following the Great Commission's decree to spread the teachings of Jesus to "all nations". Peter, Paul, and James the Just were the most influential early Christian leaders, though Paul's influence on Christian thinking is said to be more significant than any other New Testament authors, but the relationship of Paul of Tarsus and Judaism is still disputed today. The split of early Christianity from Judaism was gradual, as Christianity became a predominantly Gentile religion.
