Adult Education & Support

Rite of Christian Initiation for Adults (R.C.I.A.)

Have you received all your sacraments? Baptism, First Holy Communion, and Confirmation, are the sacraments of initiation. That means you should receive these sacraments to be fully Catholic! If you haven't, that's okay. Join R.C.I.A. and become formed in the Catholic Faith. Then at the Easter Vigil you can enter fully into the Catholic Church. Classes start mid September and go until April.

Submit this form completed to the Cathedral Center office or emailed to

Other Adults are welcome to help lead discussions and sit in class to help. If you are interested call Deacon Bob Fishman.
