Can the Roman Catholic Church deny justification by faith alone and still be considered a true church? In this episode of The Least of These Podcast, I respond to Redeemed Zoomer’s defense of Catholicism and his appeal to Gavin Ortland’s video, “Are Roman Catholics Christians?” With clarity and charity, we examine why Rome’s rejection of sola fide and penal substitution isn’t a secondary issue—it’s a different gospel. I’ll also explain why Gavin Ortland’s attempt to maintain unity with Rome leaves the door wide open for Redeemed Zoomer’s even more dangerous conclusions. If we want to love people well, we need to be clear on what the gospel actually is—and what it isn’t.
