I wrote my entire third chapter around the prophetic wisdom of Paul VI in this encyclical.
According to the Papal Nuncio to USA Archbishop Carlo Vegano two years before he became Pope, Cardinal Wojtyla said to the American Bishops:
We are now standing in the face of the greatest historical confrontation humanity has gone through. I do not think that wide circles of American society or wide circles of the Christian community realise this fully. We are now facing the final confrontation between the Church and the anti-Church, of the Gospel and the anti-Gospel. This confrontation lies within the plans of divine providence. It is a trial which the whole Church... must take up.
Nowhere is this confrontation now more marked than in the culture war of the anti-church against the family, most specially on the primary right of parents to educate their children. This sinister culture is being subtly imposed on our families in the West and brutally enforced upon families in poor countries by the West. Watch the video. Female views here.
