Are you drawn to the Catholic faith — or simply curious? The Church's door is always open. OCIA is not a test to pass or a course to complete. It is a journey of encounter with the living God, walked with a community that will accompany you every step of the way.

The Order of Christian Initiation of Adults (OCIA) is the Catholic Church's process of welcoming adults — and children of catechetical age — who are drawn to the Catholic faith. Whether you have never been baptized, come from another Christian tradition, or were baptized Catholic but never completed your sacramental initiation, OCIA is the Church's open door to you.
The name changed in 2025 from the familiar "RCIA" (Rite of Christian Initiation of Adults) to "OCIA" — not merely as a cosmetic update, but to restore a more accurate translation of the original Latin Ordo Initiationis Christianae Adultorum. The shift from "Rite" to "Order" carries real meaning: a rite suggests a single ceremony; an order describes a living, continuous process — a journey with distinct stages, each unfolding at its own God-given pace.
This is an important distinction. OCIA is not a nine-month classroom program with a fixed start and end date. The Church calls for at least one full liturgical year of formation for the unbaptized — long enough to experience Advent, Christmas, Lent, Easter, and Ordinary Time as a Catholic community lives them. And the journey can begin at any time of year. There is no waiting list. The door is always open.
At the heart of OCIA is not information but transformation. The goal is not that you know about Jesus Christ, but that you know Him — that you enter into a living relationship with Him and with the community of His Body, the Church. Everything else — the catechesis, the rites, the sacraments — flows from and toward that relationship.
You may still hear the term "RCIA" in parishes, books, and online resources — particularly those published before 2025. The process is the same; only the name and certain structural emphases have been updated. If your parish still uses the term RCIA, do not be confused — you are in the right place.
OCIA is not a single one-size-fits-all program. The Church recognizes that people come to her door from very different places. Your Baptismal status determines which path you follow — and the Church walks each path with pastoral care and individual attention.
The OCIA journey unfolds in four distinct periods, each marked by formal liturgical rites that celebrate the growth taking place. The periods are not boxes to check — they are seasons of the soul, each with its own grace and its own demands.
During the Catechumenate, formation covers the full sweep of Catholic faith and life. The following topics are typically explored over the course of one liturgical year, woven together with the Sunday Scriptures and the seasons of the Church's calendar. Each will be developed in greater depth as this resource grows.
✦ These topics follow the broad shape of the Catechism of the Catholic Church's four pillars: what we believe (Creed), how we worship (Sacraments), how we live (Morality), and how we pray (Prayer). Full treatments of each topic will be added to this page in a future update.
When Philip found Nathanael and told him about Jesus of Nazareth, Nathanael was skeptical. Philip's answer was not an argument. It was an invitation: "Come and see" (Jn 1:46). That is the spirit of OCIA. No one can fully explain in advance what it means to encounter the risen Christ in His Church. The only way to know is to come — to sit with the community, hear the Word, ask the questions, and to let God do what only God can do.
If something has drawn you to this page — even if you cannot name exactly what it is — that is already the beginning of a conversation with God. Do not wait until you feel ready. No one is ever fully ready. The Church is ready for you, now, as you are.
Find a parish near you and ask to speak with the OCIA coordinator. That first conversation is free, informal, and without obligation. It is simply a chance to tell your story and hear about theirs.
