How long do we just abide this concocted history that:
Before the Reformation there was nothing but Catholic and heritics; after the Reformation there are only Catholics, Protestants, and heritics?
Exactly. When they ask us why we give a hoot about their Roman Catholic church and its anti-Scriptural practices and beliefs it is because of the very thing you bring up -- they seek to rewrite history, and in so doing, they attempt to rewrite the history of the Christian church, as well as confusing and even defying the word of God.
Truth matters.
"For the word of the LORD is right; and all his works are done in truth." -- Psalm 33:4
Probably until things get really dramatic in these END TIMES and God is causing all those who Love Him Supremely in a given area to work together more or less without boundaries.
Even then, there will likely be Rabid Papists throwing rocks at what God is obviously doing.
And, if recent encyclical trends hold, they may be throwing more than rocks from the ranks of other globalist troops.
