The Christian Doctrine Fathers officially named Congregation of Christian Doctrine (Latin: Congregatio Patrum Doctrinae Christianae), abbreviated D.C. and also commonly called the Doctrinaries, is a Catholic clerical religious congregation of Pontifical Right for men.

As of 31 December 2020, the congregation consisted of 20 communities with 85 religious, 54 of them priests.

[1] Dottrinari priests are devoted mainly to parish ministry, teaching and publishing—especially catechetical texts.

The Congregation was founded on 29 September 1592 in L'Isle-sur-la-Sorgue, France by French priest César de Bus (1544–1607) as a community of priests devoted to the secular education of children.

The congregation was reorganized by Pope Benedict XIII and Pope Benedict XIV, who in 1747 joined the brotherhood founded in Rome in 1560 by Marco de Sadis Cusani.
