According to former communist, Bella Dodd, Russia already invaded the Catholic Church in the 1930's and now occupies the highest levels of the heirarchy in Rome.
That is right, Dr. Dodd converted in 1952, and in her autobiography,
School of Darkness, she tells how she personally trained 2,000 priests to infiltrate the Church as communists. The Vatican Council came roughly ten years after her conversion. Dodd died in 1969, so fortunately for her she did not live to see the New Mass and all of the sacrileges of the 70's.
If the communist clerics were in their twenties in the 1930's, that would have put them in their mid 50's early 60's at the time of the Council.
