A beautiful image of our Church's Iconostas at St. Mary's Orthodox Church in Saint Clair, Pennsylvania. The photo also depicts new hardwood flooring and blue carpeting that was added during our recent renovations.

Glory to Jesus Christ!

St. Mary’s Orthodox Church has been serving the community in Saint Clair, Pennsylvania since 1901. Our parish was formed by dedicated and faithful first and second generation immigrants from the Carpathian Mountains, and the former Austro-Hungarian Empire.

Our current mission is to sure up the foundation which our forefathers built, and to grow our community by witness, outreach, Evangelization, community service, and joyfulness in character.

We welcome you to our website, and encourage you to “Come and See”!
