Each formation ministry requires volunteers to fill a variety of roles. Catechists are responsible for teaching the Catholic faith through classroom lessons and activities. They commit to pursing catechetical certification and continuing education. Classroom helpers assist the catechists in various ways. They set an example for others by living their faith but do not necessarily pursue catechetical certification. The retreats and Safari and some of the other formation ministries need volunteers for a variety of non-catechetical roles such as registration and safety patrol. ALL adult volunteers who work with children in the Archdiocese of Cincinnati must complete a 3-hour VIRTUS training course and pass a background screening.
