What Difference Did Christianity Make? Why the Ancient Greeks, Romans, and Irish Converted – Fr. Terence Crotty, O.P.

Terence Crotty argues that Christianity spread so rapidly because it uniquely answered the human search for truth and happiness while transforming social life through charity, dignity for slaves and women, and a compelling vision of a good and loving God that pagan religion and philosophy could not provide.​This lecture was given on September 6th, 2025, at Dominican House of Studies.Through your gift to the Thomistic Institute, you will send the best scholars in the Catholic Intellectual Tradition directly to college campuses, bringing the light of Christ to students longing for answers. Thanks to a group of generous donors, every dollar you send up to $150,000 before December 31 will be matched.
