So you believe that all of the post-Vatican II popes didn't really understand the true teachings of Vatican II and that they were all duped by its Modernist "ambiguities". For example, the Assisi's and various other inter-religious prayer with non-Catholics once and always condemned by the Catholic Church was just a mistaken understanding of VII's false ecumenism.
If the popes didn't know the true teaching of Vatican II, who did?
There is ONE GOD. He has three manifestations or personalities: The Father, The Son and the Holy Ghost. If Jews believe that there is ONE GOD Who seems to conform to our concept of God the Father, I don't see the problem that you seem to see. When the white man had not yet seen North or South America, the American Indian tribes generally believed in the Great Spirit Who was an all powerful Being Who created each of them and our world and universe and all within that world and universe and that He had a system of eternal reward and punishment. Since they had access to neither the Bible nor to the Teaching Magisterium of the Church, did God create otherwise good and moral Indians to go to hell because they were born in, say, 900 AD?
When Jesus Christ promised to be with His Church all days even unto the end of the world, it does not take too much in the way of judgment to see that He was referencing His Church, not excommunicated Marcel LeFebvre's infernally defiant schismatic splinter or any other schism. John Paul I, Pope St. John Paul II (and particularly his excommunication of LeFebvre and his minions in schism) and Benedict XVI are proof of the faithfulness of Jesus Christ in His promise to His Church. John XXIII, Paul VI (except for Humanae Vitae) and Frankie are proof that God can also punish his Church for the evil in the pews.
I had very little interest in Vatican II when it was going on. I noted that its enthusiasts were the usual gang of secular humanists in the press and media and the usual gang of leftist malcontents in the pews. As with so much in the history of the Church that is regrettable, all this too shall pass away.
For your penance, read the National "Catholic" Reporter daily as I do and particularly the letters from the readers, a menagerie of queers, adulterers, admitted ex-Catholics, anti-war fanatics, Nuns on the Bus, Obozo lapdogs, Blase Cupich worshipers, wannabe members of Frankie's heathen legion who are just soooooooo disappointed that he has yet to enthrone satan fully in the tabernacle, especially since those fashionables had to SUFFER soooooooo long under JP I, Saint JP II, and B-XVI. Gosh darn it! It's THEIR turn now and Frankie has not accomplished their entire agenda in the first three hours of his infernal occupation of the papacy.
We have a LOT bigger problems than the long-ignored Vatican II.
