About the Show

Mere Fidelity is the flagship podcast of the Mere Orthodoxy Podcast Network. We are friends who undertake weekly conversations about theology, the culture, and the church (which is to say, just about everything). Over the last seven years, our conversations have ranged from in-depth explorations of Augustine’s Confessions, to theological analysis of the ‘nones’, to esoteric discussions about Duns Scotus and Herman Bavinck (especially Bavinck).

In addition to our freewheeling in-house discussions, Mere Fidelity invites a diverse array of guests on to the show. We have only had to apologize for Matt’s conduct toward them a handful of times.

Our History

Mere Fidelity was originally launched in May 2014 as a transatlantic fellowship of four friends who wanted to have interesting, challenging, thoughtful conversations about just about anything. We set the tone with a reading group series exploring Oliver O’Donovan’s Begotten or Made?, but also took up topics such as the Trinity in the Bible, theosis, public shaming, and worship music. Some of our favorite guests made their first appearances in these early years: Hannah Anderson, Karen Swallow Prior, Jake Meador, Todd Billings, and Andrew Wilson. (Our regulars will get the joke here.)

The “modern era” of the show began in September 2016, when we added intro music (generously provided by The Joy Eternal). In addition to dozens of one-off conversations, we recorded a short series on C.S. Lewis’ The Four Loves and a long series on St. Augustine’s Confessions. We have since hosted numerous distinguished guests, such as Timothy Keller, Rod Dreher, Ross Douthat, Carl Trueman, and Andrew Wilson.

In 2019, we hit another major milestone when we hired a show manager and began to expand our bonus offerings for Patreon supporters. In September 2020, we welcomed our first-ever sponsor, Lexham Press. In the last two years, we have recorded a mini-series on the ethics of vaccines, and a macro-series on the Beatitudes. We have also enjoyed conversations with guests like Anthony Bradley, Wesley Hill, Tara Isabella Burton, Jeremy Treat, and David French. (And Andrew Wilson.)
