St. Thomas Orthodox Church is a vibrant, God-worshiping community of Christians who proclaim the transforming message of Jesus Christ to all of Siouxland.  A fixture of Sioux City religious life, our parish is known to many by its popular twice-yearly Dinners, its participation in local charities, and its active liturgical life (please see our Calendar, for more information).  As Eastern Orthodox Christians, we embrace the truths handed down to us from the Apostles.  As Sioux Citians, we are committed to bringing the Light of Christ in Orthodox Christianity to all of our community.

At St. Thomas Orthodox Church, you will find Holy Orthodoxy–ancient and alive.
