The Christian Doctrine Fathers, or Doctrinaries (in Latin Congregatio Patrum Doctrinae Christianae), are a religious institute of male consecrated Catholics. The members of this religious congregation add the abbreviation D.C. after their names.
The institute was founded 29 September 1592 in L'Isle-sur-la-Sorgue by French priest César de Bus (1544–1607) as a community of priests devoted to the secular education of children. It was approved by the Holy See on 23 December 1597.
Later, the congregation was reorganized by Benedict XIII and Benedict XIV, who in 1747 joined the brotherhood founded in Rome in 1560 by Marco de Sadis Cusani.
Today, Dottrinari priests are devoted mainly to parish ministry, teaching and publishing—especially catechetical texts.
As of 31 December 2010, the congregation consisted of 17 communities with 89 religious, 58 of them priests.
