Adult Formation

Ongoing faith formation is essential if we want to live as a disciple of Jesus. Programs, speakers, workshops and activities take place throughout the year.

Know Jesus. Make Him known.

Becoming Catholic through OCIA

The Order of Christian Initiation of Adults (OCIA), welcomes and initiates those who choose to become Catholic by providing Catholic Christian formation. OCIA is for adults who have never been baptized, for adults who have been baptized in another Christian faith and now want to be Catholic, and for adults who have been baptized Catholic but are needing two or more sacraments.

Our OCIA program begins in September. The timeline for full initiation into the Catholic faith for those participating in OCIA varies. Unbaptized adults are typically welcomed into the Church at Easter Vigil. Adults who are baptized in another Christian faith, as well as those who are completing their sacraments, usually celebrate on Pentecost.

Becoming Catholic at Saint Irenaeus Church is a remarkable process that will change your life. Want to learn more? Call us at 714-826-0760 or send an email.

Infant Baptism Preparation

Infant Baptism is an exciting and wonderful sacrament!

Children are baptized under the condition that parents promise to raise the child as a Catholic Christian.

There are several steps for Infant Baptism, so it is important to get started at least two months before the desired baptism date.

Step 1: Fill out the Baptism Inquiry Form, available in the parish office, and provide a copy of your child's Birth Certificate or Certificate of Live Birth

Step 2: Meet with priest or deacon (scheduled when you fill out the Inquiry Form)

Step 3: Return Baptism Registration Packet (received during meeting with priest/deacon)

Step 4: Once everything has been submitted you will be contacted to schedule your preferred baptism date

Infant Baptism is for children 0 months to 6.5 years old. Please visit our Youth Ministry page for baptism of children ages 6.5 years to 12th grade. For adult baptism, please call the parish office or send an email.

"I have baptized you with water; he will baptize you with the holy Spirit."

Mark 1:8
