#49 Redeemed Zoomer vs. Transubstantiation: Does John 6 Prove Him Right? - Karlo Broussard
Redeemed Zoomer vs. Transubstantiation: Does John 6 Prove Him Right?
Catholics are fond of going to John 6 to prove Christ’s Real Presence in the Eucharist.
But Redeemed Zoomer released a video some time back arguing that Christ’s words in John 6 actually prove false the Catholic doctrine of transubstantiation.
What’s that argument?
And does it work?
Stick around and you’ll find out.

#48 What is Sex REALLY For? The Truth About Sex and Human Nature - Karlo Broussard
What is sex actually for? In this episode, I explore whether there’s an objective reality to our sexual powers and why true “sexual sanity” means living in accord with the procreative and unitive meaning built into human sexuality itself. Drawing from philosophy, natural law reasoning, and Catholic thought, I episode challenge modern assumptions about sex, pleasure, love, and human flourishing—off
#47 What Catholics Ignore in Their Interpretation of John 6? - Karlo Broussard
What Catholics Ignore in Their Interpretation of John 6?
Description: Do key verses in John 6 actually undermine the Catholic belief in the Real Presence? In this episode, I take a careful look at common Protestant objections and see whether the details really point to a symbolic reading—or reinforce the Catholic interpretation.

#45 The Protestant Dilemma: Verbal Inspiration and Sola Scriptura - Karlo Broussard
Can Protestants prove verbal inspiration from Scripture alone? In this episode, I examine the biblical case for the Protestant claim that apostolic authorship guarantees verbal inspiration—and argue that the case ultimately falls short without appealing to Sacred Tradition.
#43 Are Catholics Being Consistent in Their Interpretation of John 6? - Karlo Broussard
Transcript:
Believers in the Real Presence argue that in John chapter 6, Jesus clearly intends his audience to take him literally when he commands to “eat his flesh” and “drink his blood.” In other words, this isn’t poetic imagery, this isn’t figurative speech, and this isn’t Jesus speaking in metaphors the way he sometimes does elsewhere. The claim is that Jesus really means what he says here.
#42 Is Our Justification Rooted in Interior Righteousness? Romans Has the Answer! - Karlo Broussard
One of the big issues that divides Catholics and some Protestants is how we understand justification. Catholics believe we stand just before God on account of an interior state of holiness—called sanctification—that God brings about within us. Protestants of the Reformed Tradition, however, deny this teaching and argue that we are just before God solely because he declares us just on account of ac
#041 “Eternal Life” Means Forever Saved… Right? - Karlo Broussard
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.
#39 God: A Creator of Evil? - Karlo Broussard
Transcript:
If God created everything and evil exists, does that mean God created evil? In this episode, I unpack at least one version of the problem of evil and show how understanding evil as a privation resolves the apparent conflict with God’s goodness and creative power.
If God is the Creator of everything—as classical theists claim—and evil exists…then doesn’t that make God the crea
#038 Do Catholics Get Paul Wrong on Traditions? - Karlo Broussard
Is the tradition in 2 Thessalonians 2:15 more than the written gospel? Karlo Broussard answers James White’s objections to Sacred Tradition.
#037 James on Abraham’s Justification—Are Catholics Missing the Whole Point? - Karlo Broussard
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.
#036 The Hidden Enemy of Science - Karlo Broussard
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.
#035 Tradition and Scripture: Meeting the “Identity” Challenge - Karlo Broussard
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 Christ established an infallible teaching authority beyond the apostles, challenging the doctrine of sola scriptura through Scripture and early Church evidence.
#030 Does Scripture Alone Really Suffice? Responding to Wes Huff’s Argument - Karlo Broussard
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.
#29 Is Religious Belief a Cop Out? Debunking the ‘Thinking is Hard’ Claim - Karlo Broussard
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.
#28 Why a Bible Christian Should Believe Mary as Mother of God - Karlo Broussard
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 oth
#027 Evangelization, the Papacy, and My Journey of Faith (Interview) - Karlo Broussard

#025 Chance or Design? The Truth Behind Evolution - Karlo Broussard
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
#024 The Sight of Men or God? What James Meant by Justification - Karlo Broussard
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.
#022 Jesus the Miracle Worker—History or Legend? - Karlo Broussard
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.
#021 Is the Mass the Same Sacrifice as Calvary? A Response to James White - Karlo Broussard
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.
#020 Vain Repetition? The Truth About the Rosary! - Karlo Broussard
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.
#019 “Is Purgatory the ‘Ultimate Insult’ to Jesus’ Death on the Cross?” - Karlo Broussard
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.
#018 Does the Bible Reject the Use of Philosophy? - Karlo Broussard
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.
#017 Sacred Tradition—Overstepping Boundaries? - Karlo Broussard
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.

#014 Peter, a Regular Ole “Pillar”? - Karlo Broussard
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.
#013 Religion: A Betrayal of the Intellect? - Karlo Broussard
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.
#012 If Jesus Paid it All, Why Do Penance? - Karlo Broussard
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.

#44 How We Know the Unborn (at all stages) is a Human Person - Karlo Broussard
f the unborn is a human being from conception, can it still fail to be a human person? In this episode, I go beyond intuition and show—philosophically—why every human being, at every stage of development, is a human person with a right to life.
# You Don’t Believe in Purgatory? Paul Did!
You Don’t Believe in Purgatory? Paul Did!
When a Protestant asks, “Where’s purgatory in the Bible?” Catholics who know their apologetics usually point to 1 Corinthians 3:11–15.
But what exactly does Paul say there that makes us think he’s talking about purgatory?
Stick around and you’ll find out.
All right, on to the text. Here’s what Paul writes:
