Father Hesse has been a good guide and blessing to the Catholic remnant.
He admittedly doesn't have all the answers, but being brilliant and educated in Rome, he knows where to find them.
He describes the Council and the new mass as schismatic. That's what we need to know.
Vatican II's theology is not Catholic and fit's Pope Leo XIII's St Michael's prayer warning:
"... These most crafty enemies have filled and inebriated with gall and bitterness the Church, the spouse of the immaculate Lamb, and have laid impious hands on her most sacred possessions. In the Holy Place itself, where the See of Holy Peter and the Chair of the Truth has been set up as the light of the world, they have raised the throne of their abominable impiety, with the iniquitous design that when the Pastor has been struck, the sheep may be..."
Vatican II was the de facto Pope's official: "raising of the throne of their abominable impiety".
