Apostolic succession is the belief that the authority of the Apostles, the original followers of Jesus Christ, is passed down through an unbroken line of bishops. This succession is important for maintaining the integrity and teachings of the Christian Church. It ensures that the teachings and practices of the Church remain consistent with those established by the Apostles. In many Christian denominations, particularly in Catholicism and Orthodoxy, apostolic succession is seen as essential for valid sacraments, such as Holy Orders and Eucharist. This concept emphasizes the continuity of leadership and the importance of historical connections to the early Church.
