Early Christian movements emerged in the first few centuries after the life of Jesus Christ. These groups sought to spread his teachings and establish communities based on shared beliefs. They often faced persecution from both Jewish authorities and the Roman Empire, which led to the development of distinct practices and doctrines. As these movements grew, they began to organize more formally, leading to the establishment of various sects and the formation of the early Christian Church. Key figures, such as Paul of Tarsus, played a significant role in spreading Christianity beyond Jewish communities, contributing to its expansion throughout the Roman world.
