What is the Magisterium in Catholic theology?

• A. The teaching authority of the Church (the Pope and bishops in communion).
• B. The personal opinions of theologians.
• C. The written Scriptures alone.
• D. The ritual practices of liturgy.

Answer: (A)

The Magisterium is the Church's official teaching authority to interpret and safeguard Revelation. It is exercised by the Pope and the bishops in communion with him, who transmit and guard the truths entrusted by Christ for faith and morals. This authority binds all Christians in matters of doctrine and guides how Scripture and Sacred Tradition are read and applied. It is not the personal opinions of individual theologians, which can be insightful but are not binding on the whole Church. It is also not simply the written Scriptures alone or the ritual practices of liturgy; Catholic teaching holds that Scripture and Tradition together form the deposit of faith, and the Magisterium acts to interpret that deposit faithfully. The Magisterium operates in different ways, including the Pope’s solemn definitions and the ongoing teaching of bishops in union with him.
