St. Pius X Children's Faith Formation (CFF) helps form the faith of non-parochial school students from age 3 through 5th grade and meets on most Sunday mornings during the school year. Children's Faith Formation families are encouraged to gather together from 9:30 a.m. - 9:45 a.m. and children will go to their Children's Faith Formation rooms at 9:45 a.m. CFF teaches the religion curriculum of the Archdiocese of Indianapolis, which presents Catholic doctrine within the four-part framework of the Catechism of the Catholic Church (creed, sacraments, Christian living and prayer).
