Already Baptized Protestant Christian

What Happens When a Baptized Protestant Enters OCIA?

If you’re a baptized Protestant considering the Catholic Church, first—welcome. The Catholic Church recognizes your baptism as valid, provided it was done with water and in the name of the Father, Son, and Holy Spirit. That means you’re already part of the Body of Christ. What a beautiful starting point!


When you enter the Order of Christian Initiation for Adults (OCIA), you’re not beginning from scratch—you’re continuing a journey that God began in you through baptism. OCIA is a process of deepening your understanding of the Catholic faith and preparing to be received into full communion with the Church.

What Does "Full Communion" Mean?

Being in full communion means embracing the fullness of Catholic teaching and receiving the sacraments of Confirmation and the Eucharist. These sacraments complete your initiation and unite you fully with the Catholic Church.

The OCIA Journey for Baptized Christians
  • Inquiry Phase: You’re invited to ask questions, explore Catholic beliefs, and discern whether God is calling you to become Catholic.
  • Catechumenate (Adapted for those already baptized): While unbaptized individuals become catechumens, baptized Christians are called candidates. You’ll receive formation in Scripture, Church teaching, prayer, and sacramental life.
  • Rite of Reception: Instead of baptism, you’ll participate in the Rite of Reception into Full Communion, often during the Easter Vigil. Here, you:
  • Profess the Catholic faith
  • Receive the Sacrament of Confirmation
  • Receive the Eucharist for the first time as a Catholic
What Changes?

You don’t lose your Christian identity—you fulfill it. The Catholic Church sees this as a completion, not a rejection, of your previous faith journey. You’re embracing the fullness of truth, sacramental grace, and communion with the Catholic Church.



Your baptism was the beginning of a lifelong relationship with Christ. OCIA helps you deepen that relationship, discover the richness of Catholic tradition, and enter into the sacramental life of the Church. You’re not just joining a religion—you’re coming home.
