That's better than I hoped. Do you have a source?

Didn't the Holy See repeatedly excommunicate entire countries for being the wrong faith?

ETA: I know that fundamentalist Protestant churches like the non-denominational Evangelicals are strictly extra ecclesiam nulla salus, and are even harsh on their own parishioners.

It's kinda weird since Sola fide and Sola Scriptura are fundamental doctrine of Protestantism, you are supposed to decide what scripture means and how to get salvation, but woe if you dare suggest this to your pastor.
