He knew full well that the English Crown had sent troops to fight Calvinists and Lutherans as well as Catholics. In every case, they told the rank and file they were fighting for Christianity (the Anglican Church) against either evil Catholics or evil Heretics. He also knoew the "Catholic" French helped Lutherans revolt against the Hapsburgs because the French King fought the Hapsburgs every chance he got up to and including selling cannon to the Ottoman Turks.
Jefferson's take on history was that not permitting the establishment of a State Religion solved most problems he saw with religion and that enshrining freedom of religion right in the First Amendment solved the rest. So far his solution has worked better than anything else I've seen in history including the Peace of Augsburg that recognized specific religions but didn't outlaw the mixing of Church and State.
People who want to split hairs over theology in a civilized manner are one thing. People who love attacking others who agree that Jesus Christ is King of King and Lord of Lords who suffered and died for our sins should find a new pass time. They'd be far better off working to get rid of the secular liberal scum in elected offices no matter what such scum pretend they believe or which church the scum pretend to be a part of.
JMHO
Well said, IMHO.
