Does the Rosary violate Jesus’ warning against “vain repetition”? Karlo explores how the Rosary, rightly understood, draws us deeper into meditation on the life of Christ.

If Jesus’ sacrifice on the cross is fully sufficient, does purgatory contradict it—or reveal how its power is applied? In this episode, Karlo Broussard breaks down the “ultimate insult” objection and show how Scripture and theology point to purgatory as participation in Christ’s work, not a denial of it.

Karlo Broussard explains how Paul the Apostle in 1 Corinthians critiques worldly “wisdom,” not philosophy itself, drawing on Thomas Aquinas to show that reason rightly used can still lead to God.

Does 1 Corinthians 4:6—“Do not go beyond what is written”—undermine the Catholic appeal to Sacred Tradition? In this episode, I show why the context of Paul's writings and the broader New Testament actually point the other way, revealing that apostolic teaching was handed on both in writing and by word of mouth.

In this bonus episode, Dr. Karlo and William discuss Catholic apologetics topics like the biblical canon, sola scriptura, baptismal regeneration, and infant baptism while also highlighting Karlo’s new ministry projects and taking audience questions.

Some Protestants argue that Paul’s letter to the Galatians shows Peter was just one leader among many—not the first pope. In this episode, I explain why Galatians 2:6 and 2:9 don’t undermine Peter’s unique role and actually make good sense within the broader biblical case for the papacy.

Is religious belief a betrayal of the intellect because it isn’t scientific or because it’s “faith without evidence”? In this episode, I examine challenges from thinkers like Richard Dawkins, Lawrence Krauss, and Stephen Hawking, and argue that scientism refutes itself and that Christian faith is rooted in evidence—not blind belief.

If Jesus “paid it all” on the Cross, why would Christians need to do penance—especially during Lent? In this episode, we unpack the common objection, walk through St. Thomas Aquinas’s explanation of participation in Christ’s Passion, and look at Colossians 1:24 to show why penance doesn’t undermine the sufficiency of the Cross—but actually flows from it.

In this episode of the Dr. Karlo podcast, we explore arguments for God’s existence, the problem of evil, divine simplicity, hell, providence, and the role of miracles in Christian apologetics.

Dr. Karlo Broussard discusses where Catholics often misstep when debating justification with Protestants—especially by muddying stages, terms, and the grace–works relationship—and how clearer biblical and Tridentine framing leads to more fruitful dialogue.
