King Henry may have done it, thinking it was for his own glory, perhaps going the ways of the kings of this earth, garnering power unto himself. But we in the Presbyterian PCA believe God did it for the purposes of Reforming the Elect to God's Inerrant, Inspired and Eternal Word.
God often uses fallible men, sometimes even despite themselves, towards His purposes. The idea that He would use only infallible men would be laughable.
I think what you said is what I mean when I tell people that I pray God confound the godless Marxists. Only His power and might can take the evil they do and use it for His Purposes and Glory. God be praised!
