Welcome to St. Barnabas the Apostle Catholic Church!

Home of the Traditional Latin Holy Mass celebrated every Sunday morning at 10 a.m.

We are the blessed parish family of St. Barnabas the Apostle Catholic Church located in O'Fallon, Missouri. Established in 1961, we have been a vital and caring part of the St. Charles County community for 55 years this October! 

We thank you for visiting our website and welcome you to celebrate Holy Mass with us in the near future.  St. Barnabas is unique in the area celebrating a Traditional Latin High Mass every Sunday morning at 10a.m. and most of our weekday Masses are celebrated "ad orientum."  We welcome you and your family to come and experience the beauty and solemnity of the Trindetine Holy Mass.  If you have never received our Lord in the Blessed Sacrament while humbly kneeling at the Holy Communion rail, it could change your life!  

St. Barnabas is a smaller church community holding faithful to the teachings and the time-honored holy traditions of our beloved Catholic Faith. Perhaps you are looking for a spiritual home, some place where you can truly feel you belong and that you matter. 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!                                                                                                       

 Come Home to the Catholic Faith-Come Home to St. Barnabas!                                                                                                     


DONUT SUNDAY -August 21st after the 8:00a.m. & 10:00a.m. Holy Masses


St. Barnabas will be celebrating 30 Holy Masses for the spiritual protection of our O'Fallon Police Department.  What a blessed gift to offer those who dedicate their lives in service to us.  Thank you to our parishioners for their generosity and support.  And a very special thanks to Missy Welby who came up with this wonderful way to show our support by offering the greatest of prayers-the Holy Sacrifice of the Mass!
