CCD, in the context of the Catholic Church, denotes Confraternity of Christian Doctrine. This term identifies a religious education program of the Catholic Church, aimed at providing instruction in the Catholic faith to children, teenagers, and adults who are not enrolled in Catholic schools.
The establishment of formal religious education programs is rooted in the Church’s mission to impart its teachings to all believers. These programs offer systematic instruction in areas such as scripture, doctrine, sacraments, and moral living. Participation allows individuals to deepen their understanding of the faith, preparing them for the reception of sacraments and fostering a more profound spiritual life. Historically, the confraternity model provided a structured way to transmit religious knowledge, particularly in contexts where access to formal Catholic schooling was limited.
