Rite of Christian Initiation of Adults (R.C.I.A) is the process in which adults become full, participating members of the Catholic Church. Participants, known as catechumens go through a process of studying the Gospel, nurturing their relationship with God, becoming familiar with the Catholic teachings and practices, professing their faith in Jesus and the Church, and receiving the sacraments of initiation: Baptism, Communion, and Confirmation.
