Fr. Donald Calloway, M.I.C., a convert to Catholicism, is a member of the Congregation of Marians of the Immaculate Conception. Before his conversion to Catholicism, Fr. Donald was a high school dropout who had been kicked out of a foreign country, institutionalized twice, and thrown in jail three times. At age twenty he read a book about Marian apparitions that radically changed his life.

A. in Philosophy and Theology from the Franciscan University of Steubenville, Ohio, M.Div. and S.T.B. degrees from the Dominican House of Studies in Washington, D.C., and an S.T.L. in Mariology from the International Marian Research Institute in Dayton, Ohio. Many of his conferences and talks are available on DVD, and in addition to having written many academic articles, he is also the editor of the following books: “The Virgin Mary and Theology of the Body” (Marian Press, 2005); “The Immaculate Conception in the Life of the Church” (Marian Press 2004). Fr. Donald is currently the House Superior and Director of Vocations at the Marian House of Studies in Steubenville, Ohio.
