I stumbled recently across this post, in which the author (about 80% of the way through the article) transcribes the real Turretin’s view on Christmas. (link) Obviously, I don’t share the views of the articles’ author, even if I do share the views of Turretin, Calvin, etc., whom he cites.
Also, by the way, I enjoyed the title of his blog: “Autonomy is Madness.” How true that is!
