The Order of Christian Initiation of Adults is the program offered to non-Catholics who are interested in learning more about the Catholic Church. Children over the age of 7 also participate in a similar program adapted to their age.
Classes begin after Labor Day and run through Easter. Classes are held in the parish hall (in the basement of the church) on Wednesdays from 7:00 to 8:00 PM. Please use the parking lot door to enter. Everyone is welcome to attend any class, including Catholics who want to learn more about their faith. A list of individual topics appears below.
Those who want to join the Catholic Church are invited to choose a Catholic sponsor (or godparent) who will assist them through the program. Sponsors are encouraged to attend RCIA classes with their candidates.
For those who will become Catholic, the program concludes at the Easter Vigil when candidates are baptized or, if they are already baptized Christians, make their profession of faith.
Every parishioner is invited to be an ambassador for St. Thomas Parish. You have a critical role, since you may know other persons among your friends or family who should think about becoming Catholic. We need your help to recommend candidates who should take part.
Please find below the schedule of classes. The "CCC" numbers refer to the paragraphs in the Catechism of the Catholic Church where this material is found.
