Is James 2:24 about being justified before God—or just in the sight of others? In this episode, I break down key Protestant objections and show why James’s teaching on faith and works points to a real, grace-enabled justification before God, not mere human vindication.

Dr. Karlo features a crossover conversation unpacking the biblical case for baptism’s role in salvation, responding to common objections and highlighting its connection to forgiveness, new life, and union with Christ.

Are the Gospel accounts of Jesus’ miracles reliable history—or later legend? In this video, we explore ancient sources, skeptical critics, and historical criteria to uncover whether Jesus’ reputation as a miracle worker stands up to serious scrutiny.

Does James White’s appeal to Hebrews 10:14 really disprove the Catholic claim that the Mass is the same sacrifice as Calvary? In this episode, Karlo Broussard breaks down his argument and show how shifting definitions of “perfection” actually undermine his case and reveal a deeper harmony between Scripture and the Catholic understanding of the Mass.

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.

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.

Karlo Broussard examines 1 John 5:13 and argues that the apostle John teaches confident hope in salvation grounded in persevering faith and love—not an absolute, once-and-for-all assurance of heaven.

Dr. Karlo Broussard answers critics by explaining why occasional failure or poor practice doesn’t justify giving up apologetics, while emphasizing the need to do it well and charitably.

Dr. Karlo defends the claim that abortion is immoral by arguing that deliberately killing an innocent human being violates objective moral principles.

Dr. Karlo argues that apologetics should not be abandoned, because reasoned arguments—alongside love and prayer—remain essential for defending the faith, leading people to truth, and helping others share fully in the spiritual goods of the Catholic Church.
