Dr. Marcus Peter spent many years as a militant atheist before encountering a life-changing conversion experience. Through a consistent and prayerful study of Scripture, the Fathers, Theology, philosophy, and the intercession of the Blessed Virgin Mary, he found his way back to the Church and returned home in full communion in 2010.

Dr. Peter has studied philosophy and Alphonsian Spirituality in seminary, and received a master’s degree in Systematic Theology from Ave Maria University in 2018. He holds a doctorate in Biblical Studies from Pontifex University and is constantly working on studying Scripture deeper.

As Director of Theology for Ave Maria Radio and the Kresta Institute, Dr. Peter’s goal in the apostolate is to bring the saving Gospel of Jesus Christ and His Catholic Church to the ends of the earth. He is the host of the daily international radio program, Ave Maria in the Afternoon, produced by EWTN and Ave Maria Radio, which focuses on applying Scripture to the world’s culture. He also hosts Unveiling the Covenants, a radio/tv program produced by Ave Maria Radio that explores the covenantal love of God the Father in Scripture.
