The Congregation for the Doctrine of the Faith (CDF) is a department of the Roman Catholic Church responsible for promoting and safeguarding the teachings of the Church. Established in 1542, it originally focused on addressing heresy and maintaining doctrinal purity. Today, the CDF oversees theological matters, ensuring that Church teachings align with its core beliefs. The CDF also handles cases of clerical misconduct and provides guidance on moral issues. It plays a crucial role in the Church's efforts to clarify and defend its doctrines, contributing to the overall unity and integrity of the Catholic faith.
