Roman Catholics rely on which sources of truth?

• A. Bible only
• B. Church traditions only
• C. Personal experience
• D. Bible and Church traditions

Answer: (D)

Revelation for Catholics comes from both Sacred Scripture and Sacred Tradition, together under the guidance of the Church’s teaching authority. The Bible is the inspired Word of God, but it is part of a living tradition handed down from the apostles—creeds, liturgical practices, and the consistent interpretation of the faith by the early Church. Over time, ecumenical councils and Church Fathers clarified and safeguarded beliefs to stay true to that apostolic teaching. Because of this, truth about God and salvation is seen as coming from both sources: Scripture provides the written revelation, while Tradition preserves and explains how that revelation has been handed down and lived in the life of the Church. The Magisterium, or official teaching office, helps interpret and unify these sources. Limiting truth to either Scripture or tradition alone would miss how Catholicism understands the full, living transmission of faith. For example, doctrines like the Trinity and the Eucharist are grounded in Scripture but were clarified and defined through Tradition and authoritative teaching.
