Equip Podcast The Clarity of the Gospel: Understanding the Differences Between Catholicism and Protestantism
If both Catholics and Protestants believe we’re saved by grace through Jesus Christ, why do they still disagree so sharply about the gospel—and how we actually receive it?
In this episode, Mark continues the “Why Protestantism?” series by focusing on how grace is applied to the believer. He explains how Roman Catholicism understands grace as being mediated through the Church’s sacramental system—especially baptism and the Eucharist—and why the sacraments are seen as the ordinary channels through which God dispenses saving grace. Using a vivid “pop machine” illustration, Mark unpacks how this shapes Catholic views of salvation, assurance, and the Christian life.
Mark then contrasts this with the Protestant conviction of sola fide—that we are justified by grace alone through faith alone in Christ alone, with the preached Word at the center. He highlights areas of real agreement with Roman Catholics (salvation by grace, the transforming work of the Spirit) while also showing where the systems diverge, especially on how grace is received. Finally, he explores how these differences show up in Sunday worship and why gospel clarity matters deeply for ordinary Christians.
