It's more complex than that - see Vol I of Rothbard's [Austrian Perspective on the History of Economic Thought](https://mises.org/library/book/austrian-perspective-history-economic-thought). I would lay the fault of our credit-driven economies largely at the feet of Peel's Laws in the mid 1800s, the advent / rise of Fractional Reserve Banking--the rise of the social-gospelers like Rockefeller, and the Rothschilds, etc. and all the State paternalism that that implied.

But either way, the Reformers always taught that the moral law of God frames all activities, commerce not excluded, so I don't see how they can be accused of "separating money and religion." Interest is a necessary function of functioning economies, as all the 'Austrians' ably show.

If I may: question the sources (like Brad S. Gregory) that lay the guilt of all modern problems at the feet of the Protestant Reformers. The Protestant Reformers, in particular, were implementing (though slowly) the principles we know as "classical liberalism" two centuries prior to the American founders (see John Witte, Jr. [The Reformation of Rights: Law, Religion and Human Rights in Early Modern Calvinism](https://www.amazon.com/Reformation-Rights-Religion-Modern-Calvinism/dp/0521521610/ref=sr_1_1?s=books&sr=1-1)).
