The Rite of Christian Initiation of Adults is a program that introduces people to the Catholic faith through a series of instructions over a period of time that runs from September through Holy Week. Those who go through R.C.I.A. then make the decision to either be baptized or received into the Church at the Easter Vigil service on Holy Saturday night. They also receive the other sacraments of initiation: Confirmation and Holy Eucharist. Those who are already members of the Church may also attend these instructions as a means of reviewing their faith.
