2.1. What are the sources of divine revelation in the Catholic Church?
Divine revelation is transmitted through two inseparable sources:
Sacred Scripture – the written Word of God, inspired by the Holy Ghost,
Apostolic Tradition – the oral teachings of Christ and the Apostles, faithfully handed down through the Church.
Together, they form the deposit of faith. This deposit was entrusted not to individuals, but to the Church herself to preserve inviolate until the end of time (cf. 2 Thess. 2:15; 1 Tim. 6:20).
