RCIA stands for the Rite of Christian Initiation for Adults. It contains various rites, some of them optional, for bringing adult converts into the faith. Some of these rites are: the anointing of catechumens, the rite of welcoming, the Rite of Election, and the scrutinies. The rituals involved generally take place in the weeks leading up to the Easter Vigil, when those who have not been baptized (catechumens) receive the sacraments of baptism, confirmation, and Holy Communion.
At the core of the RCIA are the instruction classes. Before making the commitment to join the Church and become a full member of the Catholic Faith, it is imperative that adults possess sufficient knowledge of what the Church teaches (about herself, Scriptures, God, mankind, and morality) so that their decision is fully informed and made with complete freedom. .
