An ACTS retreat is a three day and three night Catholic lay retreat presented by fellow parishioners of St. Mary's. The retreat (held at Maryhill) begins on Thursday evening and ends the following Sunday at a Mass celebrated with the parish community. Retreats for men, women, and teenagers are given separately. The focus of the retreat is Adoration, Community, Theology, and Service, from which the ACTS acronym is derived. Holy Scripture and the teachings of the Roman Catholic Church are the guides for the retreats. The ACTS Ministry at St. Mary's is admnistered by a Core Team. Fr. Charlie Ray, Pastor of St. Mary's Assumption, serves as the Spiritual Director.
