For the unbaptized, OCIA typically involves about a year of preparation, though this can vary based on individual readiness. After a time of inquiry, you'll enter the Catechumenate, a deeper period of formation through prayer, community, Scripture, and service. The final stage of preparation takes place during Lent, leading to the joyful celebration of Baptism, Confirmation, and the Eucharist at the Easter Vigil — the most sacred night of the Church year.
