 The Confraternity of Christian Doctrine , also known as C.C.D. consists of men and women whose mission is to teach the principles of loving and serving God to the children of the parish who do not attend Catholic School . Members of the confraternity serve as teachers in the Sunday Schools of the parish ( there are seven different Sunday Schools belonging to Mt . St. Peter 's in total ) . These teachers send out the Catholic messages of faith and love through words , stories , examples , and prayers in order to help the children grow in their faith . The majority of children who attend one of the Sunday Schools are ages 6 – 12 .
