Rabbi Stewart Federow, Father Mario Arroyo, Dr. David Capes
Rabbi Stuart Federow is the Senior Rabbi at Congregation Shaar Hashalom in Houston and a passionate advocate for Jewish-Christian dialogue. With a mind sharpened by years of interfaith conversation — and a humor sharper still — Rabbi Federow brings clarity, conviction, and a deep love for tradition to every discussion. He’s also the author of "Judaism and Christianity: A Contrast," because nothing says interfaith friendship like a well-reasoned rebuttal.
Father Mario Arroyo is a Roman Catholic priest of the Archdiocese of Galveston-Houston, known for his pastoral heart, philosophical insight, and a killer homily game. When he’s not celebrating Mass or counseling parishioners, he’s bridging centuries of Catholic teaching with the modern world — all while keeping a sense of humor worthy of a Jesuit retreat gone rogue.
Dr. David Capes is a respected New Testament scholar, author, and professor with a gift for making scripture accessible without dumbing it down. As a representative of Protestant Christianity, he offers a thoughtful, biblical perspective that is both scholarly and deeply pastoral. When he joins Rabbi Federow and Father Arroyo, the result is part seminary, part stand-up — and all substance.
A Show of Faith
"A Show of Faith" on KNTH-AM is where Houston’s most thought-provoking religious voices come together for one deeply respectful — and occasionally delightfully irreverent — conversation about life, faith, culture, and current events. Hosted by Rabbi Stewart Federow, Father Mario Arroyo, and Dr. David Capes, this one-of-a-kind broadcast explores the intersection of Judaism, Catholicism, and Protestant Christianity in a way that’s informative, engaging, and often sprinkled with good-natured theological banter. Whether they’re unpacking sacred texts or laughing about the week's headlines, these three friends bring wisdom, wit, and grace to every topic under the sun (and sometimes beyond it).
