The Dicastery for the Doctrine of the Faith (DDF) is a department of the Roman Curia in charge of the religious discipline of the Catholic Church.

[1] This institution was founded by Pope Paul III on 21 July 1542, as the Supreme Sacred Congregation of the Roman and Universal Inquisition.

"[1] The congregation employs an advisory board including cardinals, bishops, priests, lay theologians, and canon lawyers.

On 1 July 2023, Pope Francis named Argentine archbishop Víctor Manuel Fernández as prefect, who took possession of the office in mid-September.

[3] On 21 July 1542, Pope Paul III proclaimed the Apostolic Constitution Licet ab initio, establishing the Supreme Sacred Congregation of the Roman and Universal Inquisition, staffed by cardinals and other officials whose task it was "to maintain and defend the integrity of the faith and to examine and proscribe errors and false doctrines."

In many Catholic countries, the body is often informally called the Holy Office (e.g., Italian: Sant'Uffizio and Spanish: Santo Oficio).

The changes of the new version concern "harmonising the norms with the revised Book VI of the Code of Canon Law, which was promulgated in May 2021" and adding "numerous normative measures of various kinds issued in previous years, especially since 2016.

The CDF holds biennial plenary assemblies, and issues documents on doctrinal, disciplinary, and sacramental questions that occasionally include notifications concerning writings by Catholic theologians.

[25] On his appointment as prefect, Cardinal Fernández was instructed to focus on the Dicastery's doctrinal work and leave the disciplinary section alone.
