Ignatius Press

June 2, 2025
Dr. Peter Kreeft is a well-known Catholic figure who has helped many people convert to Catholicism and deepen their love and understanding of the faith. But few know that Dr. Kreeft himself is a convert to Catholicism. Raised Calvinist, Dr. Kreeft ended up becoming Catholic after attending Calvin College in Michigan, and in his new book “From Calvinist to Catholic,” Dr. Kreeft details his conversion story in his typical vivid and whimsical style.
Today, Andrew Petiprin, also a convert, is joined by Dr. Kreeft and the two discuss Dr. Kreeft’s youth, his process of conversion, and what drew him into full communion with the Catholic Church. They also discuss the relationship between Protestants and Catholics, and their hope that more Christians would enter more fully into the sacramental life of the Church.
This is a must-see episode, if you have read anything by Dr. Kreeft because it reveals a more personal side to one of the bright lights in the Church.
