Dr. Manchester joined the faculty in Fall 2014, teaching philosophy in the College Division. Courses taught at St. Charles Borromeo include Logic, Humanities, and the Philosophy of Miracles. He has taught at two other Catholic colleges, including 10 years at Caldwell College (now University) in New Jersey, serving as chairperson of the department of theology and philosophy for three years. His training is broadly in the history of philosophy, with specialization in early modern philosophy, as well as ethics and political philosophy. Though he entered the Catholic Church shortly after completing his PhD, he has remained active in both Catholic and Protestant academic societies (including the Wesleyan Philosophical Society, for which he served as President in 2006), the American Maritain Association, the Society of Catholic Social Scientists, in addition to the pro-life academic society the University Faculty for Life.
