Welcome to St. Barnabas the Apostle Catholic Church!

St. Barnabas the Apostle Catholic Church is located in O'Fallon, Missouri at the corner of Main Street and Highway P.  Established in 1961, we have been a vital and caring part of the St. Charles County community for 60 years.  St. Barnabas is a smaller church community holding faithful to the teachings and time-honored holy traditions of our beloved Catholic Faith.  

We are blessed to be the only Catholic Church in the St. Charles Deanery to celebrate the Traditional Latin High Mass every Sunday morning at 10:00AM  Vespers (Evening Prayer) is held every Saturday at 4:30PM and Lauds (Morning Prayer) every Sunday morning at 8:00AM.

Perhaps you are looking for a spiritual home-Some place where you can truly feel you belong and that you matter, a parish dedicated to doing everything for the glory of God-you may find what you are searching for right here with us at St. Barnabas.   We are a dedicated and prayerful group of people sharing our journey in this life, growing together in the goodness of God through His Beloved Son Jesus Christ, as we await our heavenly home and we welcome you to join us on our journey!

May God Bless you and your family and keep you in His care.
