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 the only Catholic Church in the St. Charles Deanery to celebrate the Traditional Latin High Mass every Sunday morning at 10:00AM.  Our parish is blessed to welcome  visiting priests throughout the area to celebrate this beautiful Mass for us. 

Lauds (Morning Prayer) is held every Sunday morning at 8:00AM.

Please visit us one Sunday soon!
