Scanlan orchestrated many other changes at the university. He instituted an Oath of Fidelity to the Magisterium, which was required of the theology professors at the university. Under his guidance, the undergraduate theology program became the largest of any Catholic university in America. He also created the Human Life Studies minor, the only one of its kind in America. By 2000, Scanlan’s leadership and changes had helped the university to increase dramatically in size; there were more than 2,100 students, nearly double the number in the early 1970s.
