Dr. Marcus B. Peter, Th.D. — biblical theologian, international speaker, and daily host on the EWTN global Catholic radio network.
A former militant atheist. A Protestant preacher who argued against Rome. A scholar who studied his way into the Catholic Church in 2010 — and has spent every year since telling the world why.
Received into full communion through a prayerful study of Scripture, the Church Fathers, philosophy, and theology, Dr. Peter now serves as Director of Theology for Ave Maria Radio, successor to Al Kresta at the daily microphone, and host of the TV series Unveiling the Covenants.
The argument, in print.
Dr. Peter's books bring the same clarity and conviction of his preaching to the page — biblical theology, Catholic apologetics, and the case for the faith, written for ordinary Catholics and serious inquirers alike.
