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.

In this episode, Dr. Karlo critiques a popular Protestant argument for Sola Scriptura, showing that its appeal to biblical inspiration commits a logical fallacy by wrongly assuming that only inspired authorities can be infallible.

In this episode, Dr. Karlo Broussard refutes four counterarguments, showing they fail to undermine his interpretation of 1 John 5:13 or support the doctrine of eternal security.

Dr. Karlo Broussard challenges the idea that religion is for the uneducated by showing how data, expertise, and great thinkers reveal faith and reason as allies, not enemies.

In this episode, Dr. Karlo Broussard chats with Adrian Lawson from Sips with Serra about where Catholics go wrong when critiquing Sola Scriptura.
