How are Sacred Tradition and Sacred Scripture safeguarded against error?

• A. The Magisterium, in unity with the bishops and the Pope, authentically interprets and preserves both Scripture and Tradition.
• B. The local parish priest alone interprets Scripture.
• C. Each believer interprets Scripture independently.
• D. Civil authorities oversee the transmission of Tradition.

Answer: (A)

The key idea is that the Church’s teaching authority protects both Sacred Scripture and Sacred Tradition from error. The Magisterium, acting in communion with the bishops and the Pope, exercises authentic interpretation and faithful preservation of Scripture and Tradition. This authority, guided by the Holy Spirit, aims to safeguard the deposit of faith in matters of faith and morals, ensuring a coherent and true transmission from the apostles to all generations.

Relying on a single parish priest, on private interpretation by individual believers, or on civil authorities cannot provide the same unity or doctrinal fidelity, and would undermine the continuity and authority entrusted to the Church to guard and interpret the faith.
