Mary Dufresne Harper was raised a cradle Catholic in New Orleans, LA where she encountered the Lord while participating in the Catholic Charismatic Renewal of New Orleans and ecumenical prayer groups. She received her Masters of Arts and Bachelor of Arts in Theology from Ave Maria University where she met her husband, John-Paul Harper (a fellow theologian). One of her greatest joys was teaching high school theology for four years at an all-girls Catholic school on the East Coast. She continues writing for Litany NYC a Catholic made-to-measure clothing company that prioritizes Catholic Social Teaching in their production process.
