Why are some Protestants drawn toward Roman Catholicism—and how should we think about the “one true church”? In this episode, Mark Vance launches a five-part series on the nature of the church, explaining why he remains a Protestant while seeking to speak with both clarity and charity about Catholicism.

Mark walks through why historical rootedness feels especially compelling in shaky cultural moments, how true Christianity exists within the Roman Catholic Church, and yet why he believes certain teachings and practices obscure the gospel. He also introduces the four major reasons he’s a Protestant: the nature of the true church, the history of the church, the question of authority, and the clarity of the gospel—setting the stage for the rest of the series.

What does the Tenth Commandment have to do with Target runs, Amazon carts, and Instagram ads? In this episode, Mark and Emily explore “Do not covet” and talk honestly about living in a world designed to stir desire and fuel discontent.

They discuss why coveting runs deeper than wanting stuff — it’s about wanting someone else’s life — and why modern advertising, comparison culture, and curated online lifestyles make contentment both harder and more essential. With practical ideas like 24-hour purchase rules, fasting from buying, gratitude habits, and learning to rejoice in others’ good, this conversation invites us into a lifestyle shaped by worship, simplicity, and joy in God’s provision.

From political ads to Instagram comments, this conversation invites us to reflect Christ not only in what we say, but how we say it.
