Dr. Marcus Peter spent many years as a militant atheist before encountering a life-changing conversion experience. He was with the Assemblies of God as a praise leader and itinerant preacher for two years. 

    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. He has given tens of thousands of talks across the world on the faith. 

    Dr. Peter has an undergraduate degree in Communications with minors in Marketing and Management. He studied philosophy and Alphonsian Spirituality in seminary, and received a master’s degree in systematic theology from Ave Maria University in 2018. Most recently, he holds a doctorate in biblical studies from Pontifex University.

    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 joined Ave Maria Radio as a radio and tv host in 2022 and as Director of Marketing in 2023. He now functions as the Director of Theology for Ave Maria Radio and oversees all theological considerations for the work and content produced by Ave Maria Radio. Dr. Peter’s program, Unveiling the Covenants, is a deep dive of the Scriptures, exploring the covenantal love of God the Father in the pages of the bible. A mentee of and successor to Al Kresta, Dr. Peter hosts the daily international radio program,  Ave Maria in the Afternoon. On this program, Marcus applies the truths of Catholic Biblical Theology to all facets of life and the culture.

    Dr. Peter is a prolific author and speaker, and he continues to speak and write on a wide array of topics since the truth of Christ and His Church have bearing upon all areas of human life. A number of his books are in the process of publication.
