Welcome, I am delighted that you have chosen to learn more about us and our parish community. We are located in western Howard County and although we are a large community, visitors to our church invariably remark about the friendliness and warmth of the people and staff at St. Louis.

Much like our Catholic faith, our parish history and roots run deep, beginning at the Chapel of Doughoregan Manor, home of Charles Carroll of Carrollton (1737-1832), the only Catholic signer of the Declaration of Independence. Our first “public” church was built in 1855, has been lovingly restored and now serves as a wayside chapel for our parish cemetery on Ten Oaks Road. In 1889 our second church, a beautiful stone Gothic chapel, was built on our campus here in Clarksville, and is very much in use today for daily prayer, adoration, baptisms, weddings, and funerals. Our parish continued to experience tremendous growth and in 1980 a new and larger church was built to accommodate that growth. However, continued growth over the last two decades necessitated the building of an even larger church which was dedicated in April of 2006.

If I were asked to describe the spirit of this community, I would say that it is a community that is very much in tune with the times–proud to be exceptionally active and involved in a broad array of ministries and activities while at the same time respecting and advocating the basic traditional Christian values that the Gospel proclaims. Please feel free to visit–you are always welcome!

Sincerely in Christ,
Msgr. Joseph L. Luca

Haiti Ministry

Advent Wreath Lighting

If you wish to participate in lighting the Advent Wreath at the beginning of Mass and take up the Offertory Gifts during the Sundays of Advent, please sign up in the Narthex. We have written instructions on what to do, and we can help with any questions you have to make it easy. This beautiful symbol of waiting for the Lord’s birth is an opportunity for everyone – from individuals to couples to families with children.
