Excellent article, I'm very familiar with it. I've read that whole work and it was incredibly eye-opening. Reading that and his _The Progressive Era_ were revolutionary for my thinking.
What's very interesting to me personally is, my (Christian) denomination was formed as a protest against the modernist tendencies of the PCUS in the mid- to late-1920s. In studying the history of the controversies that led to the ejection of J. Gresham Machen and the formation of the [OPC](https://opc.org), there were a surprising number of names dropped in Rothbard's works that had already been made known to me by studying the history of my own denomination. E.g., President Wilson (hisssss) was a neighbor of one of my favorite theologians (Geerhardus Vos), and a contemporary of J. Gresham Machen. His entire project of "postmillennial pietism" was part of the reason we were "kicked out" of that mainstream denomination.
FEE has published a couple of short homages to Machen:
- Lawrence W. Reed, "[J. Gresham Machen: God's Forgotten Libertarian](https://fee.org/articles/god-s-forgotten-libertarian/)" (2015)
- Daniel Walker, "[J. Gresham Machen: A Forgotten Libertarian](https://fee.org/articles/j-gresham-machen-a-forgotten-libertarian/)" (1993)
And the Mises Institute gave a "Brown Bag Seminar" back in 2009 about Machen:
- Shawn Ritenour, "[J. G. Machen: Calvinist, Revolutionary, Hero](https://mises.org/podcasts/individual-lectures/j-g-machen-calvinist-revolutionary-hero)"
You can get a sampling of Machen's arguments here: [Christianity and Liberalism](https://www.monergism.com/thethreshold/sdg/machen/Christianity%20and%20Liberalism%20-%20J.%20Gresham%20Machen.pdf) (Free PDF) - note: by 'liberalism' he meant modernism (the rejection of the supernatural). And, there's also his appeal made to Christian Educators (prior to the founding of the Dept. of Education), which he made within a few months of Hitler's "What are you? We already have your children!" speech in Germany: [The Necessity of the Christian School](https://www.pcahistory.org/documents/necessity.html). In this speech he argues that one of the primary purposes of Christian Education is the preservation of liberty. Also very informative (even entertaining) is Machen's [testimony before congress](https://reformed.org/christian_education/Machen_before_congress.html). Hero, indeed!
...which is why I always exhort people to #ReadMachen and #ReadRothbard !
