Holy Trinity Seminary

Holy Trinity Seminary Holy Trinity Seminary offers excellence in human, intellectual, spiritual and pastoral formation for Mary’s Seminary in Houston.

In 1965, near the end of the Second Vatican Council, Holy Trinity Seminary was founded by Bishop Thomas K. Gorman, the Bishop of what was then known as the Diocese of Dallas-Fort Worth. Bishop Gorman’s leadership supported by the priests, religious, and laity of North Texas helped to give Holy Trinity Seminary a firm beginning for the sake of the development of the Catholic faith in North Texas an

d throughout many parts of the United States. Bishop Gorman established Holy Trinity Seminary in association with the University of Dallas in order that seminarians might receive human formation and a sound education within the Catholic intellectual tradition provided by the curriculum and student life of the University. Between 1965 and 1986, Holy Trinity Seminary was an eight year seminary providing both collegiate and theological formation and education for seminarians from dioceses across the United States of America. In 1986, Bishop Tschoeppe of Dallas and Bishop Fiorenza of the Diocese of Galveston-Houston agreed to cooperate in the work of seminary formation by maintaining a collegiate program of formation at Holy Trinity Seminary and a graduate program of theological formation at St. Throughout its history, Holy Trinity Seminary has been privileged to prepare men for priestly ministry in the dioceses of Texas, Oklahoma, Arkansas, Louisiana, Kansas, Nebraska, Alaska, South Carolina and others.
