RCIA (Rite of Christian Initiation of Adults) is the process by which non-Catholics enter the Catholic Faith. To become a Catholic, one must understand the teachings of the Church, believe in those teachings, and be a baptized Catholic. If someone is not baptized, through RCIA they will learn the tenants of the Catholic Faith and conclude their journey with the reception of the Sacrament of Baptism into the Church. If someone was baptized as a Protestant, they will study the teachings of the Catholic Faith in RCIA and conclude their journey with their entrance into the Church by a priest, which may include conditional Baptism.RCIA requires not only academic preparation but also a commitment to the Church's teachings.

RCIA classes typically begin at parishes each year in autumn and conclude before Easter, with Baptisms taking place at the Easter Vigil Mass on the night of Holy Saturday.
