Jesus says in John 5:24 that those who believe already have eternal life. Does that mean once we're saved, we're always saved? In this episode, I explain why that conclusion doesn’t follow and how understanding what Jesus means by “eternal life” helps clarify the issue.
Karlo Broussard responds to James White’s claim that the oral traditions in 2 Thessalonians 2:15 were a closed body of revelation identical to Scripture.
Is the tradition in 2 Thessalonians 2:15 more than the written gospel? Karlo Broussard answers James White’s objections to Sacred Tradition.
Do Catholics misread James 2:24 when it says we’re “justified by works and not by faith alone”? In this episode, Karlo Broussard examines arguments from R. C. Sproul and show why James’s teaching about Abraham actually fits the Catholic understanding of justification.
Could a worldview that praises science actually destroy the foundations of science? In this episode, Karlo Broussard explains why scientism—the belief that science is the only source of real knowledge—ends up undermining rational inquiry, the human mind, and even science itself.
Karlo Broussard argues that the New Testament presents divine revelation as both Sacred Scripture and Sacred Tradition, undermining the claim that all apostolic teaching was later preserved in Scripture alone.
This episode examines whether the Catholic Mass’s use of wine is contrary to the Bible and explains why Christians need not view drinking wine as an abomination.
This episode examines whether Jesus’ reported healings of the blind are historically reliable evidence that he was the promised Messiah and Son of God.
This episode examines whether Christ established an infallible teaching authority beyond the apostles, challenging the doctrine of sola scriptura through Scripture and early Church evidence.
Wes Huff recently argued that Scripture is sufficient because it alone is the “speech of God.” In this episode, Karlo examines his argument step-by-step and explain why it ultimately fails.
Is religious belief really just a “cop-out” for people who don’t want to think? In this episode, I respond to the popular atheist slogan “Religion… because thinking is hard” by exploring what belief actually is and that Christian belief does involve careful, hard intellectual work.
Is calling Mary the Mother of God biblical? This episode explores key passages like Luke 1:43 and Galatians 4:4, along with early Christian testimony and even Reformers like Martin Luther and John Calvin, to show why this ancient title flows directly from Scripture and historic Christian belief. TRANSCRIPT: The Council of Ephesus in A.D. 431 declared Mary to be the Theotokos—the God-bearer. In other words, it proclaimed Mary to be the Mother of God. But should a Bible Christian believe that? Is there any evidence from Scripture that Mary is the Mother of God? Stick around—and you’ll find out.
In this episode of Dr. Karlo, Karlo Broussard reflects on his journey from Cajun musician to Catholic apologist while discussing evangelization, the papacy, Protestantism, philosophy, and the intellectual coherence of the Catholic faith.
In this episode, Karlo Broussard responds to Gavin Ortlund by defending Marian prayer and the Catholic practice of invoking the saints.
In this episode, Karlo Broussard responds to thinkers like Richard Dawkins and Christopher Hitchens, challenging the claim that evolution’s randomness eliminates the need for God by showing that chance actually presupposes an underlying order or design. Drawing on classical philosophy and Thomas Aquinas, I argue that evolutionary processes can fit within divine providence, rather than undermine it.
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.
