The Apostolic Age marked the birth of Christianity, as early followers of Jesus formed communities and spread their faith. This period saw the emergence of house churches, communal living, and the rapid growth of Christianity across the Roman Empire, despite facing persecution and internal challenges.

Key figures like Peter, Paul, and James played crucial roles in shaping early Christian theology and practice. The Council of Jerusalem addressed the integration of Gentile converts, marking a significant shift in the Church's identity and mission. These developments laid the foundation for the early Church's growth and expansion.
