This gentleman in the video has only scratched the surface when offering his take on "ambiguities" in the Documents of Vatican II. In order to understand what the Holy Spirit accomplished working in and through the Second Vatican Council, now only beginning to be fully implemented, he would do well to read the work of a famous peritus in attendance. For the years 1965-1978, when the forces of neomodernism had infiltrated the Church, the best interpretation is that of Paul VI. For one interested in the history of the Church since Vatican II, read The Smoke of Satan in the Temple of God.
