These crimes, in Sacramentorum sanctitatis tutela a motu proprio of 2001, come under the competency of the Congregation for the Doctrine of the Faith. In effect, it is the "promoter of justice" that deals with, among other things, the question of priests accused of paedophilia.
  Within the DDF are the International Theological Commission and the Pontifical Biblical Commission. The Prefect of the DDF is ex officio president of these commissions.
  On 7 December 2021, Pope Francis promulgated a new version of the "Norms on the Delicts Reserved to the Congregation of the Doctrine of the Faith"; the original version had been first promulgated in 2001 by John Paul II and amended in 2010 by Benedict XVI. 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."
