Apostolic Tradition refers to the teachings and practices passed down from the apostles, the early followers of Jesus Christ. It encompasses the beliefs and rituals that were not explicitly written in the Bible but are considered essential to the faith. This tradition is vital for understanding the development of Christianity and its teachings over the centuries. In many Christian denominations, Apostolic Tradition is seen as complementary to Scripture. It includes the interpretations and teachings of early church leaders, known as the Church Fathers, who helped shape the beliefs and practices of the faith. This tradition is often upheld in the Catholic Church and Eastern Orthodox Church as a source of authority alongside the Bible.
