GETTING STARTED
What is OCIA/RCIA?
OCIA—the Order of Christian Initiation of Adults—is the current title used in the United States; RCIA remains a familiar search term and is still used in other English-speaking regions. Both names point to the Church’s catechumenal process, not simply to a classroom course.
This 26-stage study companion moves from free inquiry and the Gospel through the foundations of Catholic faith, the Sacraments of Christian Initiation, mystagogy, and life as a neophyte. Online study can help you prepare and review, while your local parish accompanies your discernment and celebrates the rites and sacraments.

QUESTIONS
Frequently asked questions about OCIA/RCIA
What is the difference between OCIA and RCIA?
OCIA is the title of the current English liturgical book in the United States. RCIA is the former U.S. title and remains widely recognized, while some other English-speaking bishops’ conferences still use Rite of Christian Initiation of Adults. The local parish can tell you which name and edition it follows.
What is the Catholic catechumenate?
The catechumenate is a gradual initiation into Christian faith and life for unbaptized people. It includes catechesis, conversion, prayer, liturgical rites, service, and participation in the life of the Church.
How long does OCIA/RCIA take?
There is no single worldwide duration. The pace should respect each person’s faith, conversion, prior formation, and pastoral circumstances rather than treating initiation as a fixed number of classes. Ask your parish about its calendar and discernment process.
Can online lessons qualify me for Baptism?
Not by themselves. These lessons support learning and reflection, but readiness, the rites, and admission to the sacraments belong to the pastoral process of a parish or diocese.
What is the difference between a catechumen and a candidate?
A catechumen is an unbaptized person formally admitted to the catechumenate. A baptized Christian preparing for reception into full communion is not baptized again and follows preparation suited to that person’s circumstances; in many places that person is called a candidate.
Which sacraments do adult catechumens receive?
The Sacraments of Christian Initiation are Baptism, Confirmation, and Eucharist. In the Latin Church, an unbaptized adult ordinarily receives all three in the same initiation celebration after suitable preparation.
What are mystagogy and a neophyte?
A neophyte is a newly initiated Christian. Mystagogy is the period after initiation in which the neophyte and community deepen their understanding of the mysteries celebrated and learn to live them faithfully.
May I study if I have not decided to become Catholic?
Yes. Inquiry should be free of pressure. You may learn, ask questions, pray, and speak with a parish while continuing to discern your response in freedom.
