Welcome to St. Barnabas the Apostle Catholic Church

Home of the Traditional Latin Holy Mass


We Gather and Worship Together

We are the blessed parish family of St. Barnabas the Apostle Catholic Church in O'Fallon, Missouri. Our parish is faithful to Catholic teachings and holy traditions.  We have been a vital part of the O'Fallon community for over 50 years. 

St. Barnabas is unique to this area, celebrating the Traditional Latin Holy Mass every Sunday at 10a.m.  During the Lenten season, our Thursday 8:00AM Holy Mass is celebrated as a Traditional Latin Low Mass.  Many of our daily Novus Ordo (New Order) Holy Masses are offered "ad orientem." We are a growing, vibrant, and welcoming parish family and we invite you to visit us soon!
