Rooted in Catholic Tradition
Founded in 1903, with a mission dedicated to the teaching of spirituality, diversity, and ministry, OST continues to provide theological education that transforms lives. In 1849, the Missionary Oblates of Mary Immaculate (OMI), an international apostolic religious congregation of priests and brothers, came to San Antonio. Their mission is to preach Christ’s message and serve the people of God, especially the poor and marginalized.
