Intellectual formation

During their time at the university, seminarians undergo studies in philosophy and letters. This degree was designed specifically for seminarians, as it seeks to prepare them for their later priestly duties—particularly such that they gain a robust knowledge of first principles, which will in turn help their preaching, intellectual life, and ability to tend to the spiritual needs of parishioners.

Human formation
In addition to their coursework at the University of Dallas, seminarians preparing for the priesthood at Holy Trinity Seminary are assigned house jobs and a weekly, communal work order so they learn to think of the seminary as their house and to accept responsibility for its maintenance.

Alleged involvement in sexual scandals
In the 1970s Holy Trinity Seminary is accused of having ignored and lied about seminarians who were sexually abusive towards others, especially those who showed signs of homosexuality. One of the most infamous cases is of Rudolph (Rudy) Kos who entered the seminary at the age of 30 despite the fact that he had an abusive record from his previous marriage and having failed the psychological evaluation, and was later revealed to be a pathological liar and to have sexually abused his two brothers growing up. Kos was eventually ordained for the Roman Catholic Diocese of Dallas in 1990 and has been accused of abusing multiple boys before he was removed from the ministry in 1992.
