The Catholic Concept of Tradition

Catholics accept the Bible as inspired, just as Protestants, but they also accept “Tradition.” This means that they believe that other teachings were handed down from Jesus and the apostles, truths that were not included in the Bible, but were passed down orally from generation to generation, preserved divinely among the authorities of the Church.
