Mortification of Spin

Carl and Todd welcome Chris Castaldo back to the podcast to shed some light on the apparent trend of young evangelicals converting to Roman Catholicism. Chris, lead pastor of New Covenant Church in Naperville, Illinois, and author of Why Do Protestants Convert?, has some excellent insights into this movement. Together they explore the factors influencing this shift, including the appeal of liturgy, historical rootedness, and the search for intellectual depth in faith. 

We do hear people talking about a desire for more textured liturgy, more historical rootedness, you know, a personal faith that is embodied. – Chris Castaldo

Tune in for insights on how pastors can better equip their congregations to understand these dynamics and build and maintain a strong foundation in their churches.

A new form of relationship estrangement is afoot. Whereas, in the past, relationships tended to rupture over issues like abuse, today, people are increasingly estranged because of politics.

On today’s episode of Mortification of Spin, Carl and Todd engage in a thought-provoking discussion with author Noelle Mering about her book, No Contact: How a Seductive Ideology Broke Families and Friendships and How We Can Repair Them. They explore the rising phenomenon of estrangement among families and friends, particularly among young adults cutting ties over ideological differences. 

The no contact movement is mostly young adults cutting off their parents over politics and ideology. -- Noelle Mering

Certainly, the emotional toll this has on families is immeasurable, but Noelle offers guidance for those navigating these complex relationships. According to Noelle, if we cannot hold fast to one another in the face of disagreement, we risk losing not only our most intimate bonds but also the foundation of a free and humane society.

Awake, Not Woke by Noelle Mering

Western culture impatiently demands practical results and therapeutic comfort. Many within the church have even adopted this mindset, falsely believing that God is most important when he is tending to our earthly needs. How can we help churches resist this pragmatic approach and instead embrace the mystery, awe, and reverence of our great God? 

Today, the dynamic duo discusses Carl’s latest book, Classical Theology for the Modern Mind, exploring the significance of creeds, the concept of theological retrieval, and the implications of historical theology on contemporary Christian worship. 

The Church fathers never considered their efforts to understand God to be vain philosophy, but a pious duty to get God right. – Carl Trueman

With insights drawn from their own experiences and observations in the Church, they delve into how a deeper understanding of traditional doctrines can enrich our faith and practice today.

Crisis of Confidence by Carl Trueman

Today, Todd and Carl welcome back theology professor N. Gray Sutanto to the podcast. They discuss the profound contributions of Herman Bavinck, drawing on the new book, The Essential Herman Bavinck: A Reader and Commentary, to which Gray contributed. The conversation delves into Bavinck's legacy, his approach to engaging with contemporary issues, and the relevance of his theological insights in today's pluralistic society. 

Bavinck was trying to not only capture but also transmit the scholastic reform orthodox tradition for the modern age. – Gray Sutanto

From Bavinck's thoughts on the interplay between faith and science to his vision for Christian engagement in public life, this conversation is rich with insights for anyone interested in Reformed theology and its application in the modern world.

If you're like me, and if you've worked your way through the multi-volume dogmatics that Bavinck wrote, something like this could be very helpful for you. – Todd Pruitt
