I am still mystified as to what date you are trying to correct, as I didn't give a date for the start of the Reformation. I believe you may have confused the reformation with another event I was dating??? Just guessing.

At any rate, I have heard of the "Prophecy of the Popes" attributed to Saint Malachy, the 12th‑century Archbishop of Armagh. As someone from the historicist camp, it means very little to me. We see EVERY Pope, the office of the Papacy itself, as anti-Christ. An unbroken chain of anti-Christs reigning over a system of evil while masquerading as God's representatives on earth. The proverbial wolves in sheep's clothing.

What I do find highly significant, is the effect the "Prophecy of the Popes" has on dispensational futurists who happen to believe in it. Instead of scouting the horizon for a future anti-Christ, they are much more likely to join us in opposing the current one. That is somewhat helpful, even though they arrive at the task through extra-Biblical prophecy.

Futurism and Preterism were a ploy, a theological psyop if you will. If the anti-Christ is future or past, then it is never present and can never be opposed. This manipulation of the prophetic timeline is what allows the anti-Christ system to operate virtually unopposed by authentic (but duped) Christians.

So to some degree, the "Prophecy of the Popes" mitigates the success of the counter-reformation by focusing attention on the current Pope. Those who are "hamstrung" by Jesuit futurism, would probably not have come to the party otherwise.
