Blessed Trinity is very fortunate to have St. Joseph's Roman Catholic Church next door to our school. School Masses, prayer services, and retreats are held at the parish. Blessed Trinity draws students from six elementary schools and three local parishes. The parishes include St. Joseph's Roman Catholic Church in Grimsby, St. Helen's Roman Catholic Church in Lincoln, and St. Martin's Roman Catholic Church in Smithville. However, priests from the Haldimand Deanery of the Diocese of St. Catharines, offer their time and pastoral services when needed (for example the Sacrament of Reconciliation) and support initiatives such as the Pilgrimage.
