Early Christianity refers to the period of the Christian faith's development from the life of Jesus Christ in the 1st century to the establishment of the Nicene Creed in the 4th century. During this time, followers of Jesus spread his teachings throughout the Roman Empire, often facing persecution. Key figures included the apostles, such as Peter and Paul, who played significant roles in spreading the message and establishing communities. The early Christian community was characterized by its emphasis on communal living, prayer, and the sharing of resources. Believers gathered in homes for worship and to discuss the teachings of Jesus. The formation of the New Testament canon began during this period, as early Christians sought to preserve and share their beliefs and experiences.
