CCD stands for Confraternity of Christian Doctrine. It represents a religious education program of the Catholic Church, designed to instruct children and adults in the tenets of the faith. These programs typically supplement religious instruction received at home and provide systematic learning of Catholic beliefs, practices, and traditions.
The importance of these programs lies in their role in fostering a deeper understanding of Catholicism and promoting active participation in the Church community. They offer structured learning environments where individuals can explore theological concepts, learn about the lives of saints, and prepare for sacraments. Historically, it has served as a vital instrument for catechesis, especially in regions where Catholic schools are not universally accessible.
