"Those who defend Vatican II, and condemn those who object to it, need to own the implications."
“orthodox” phrases from Vatican II do not help its defenders, as we are not weighing its statements in scales, or engaging in a game of hermeneutics. Pope St Pius X, and other popes, explicitly warned Catholics about those who speak in an orthodox way in one place, and a heterodox place in another. Such appeals require a naivety which sixty years do not permit.
Conclusion—the point stands
In any case, even these far-fetched defences of the Vatican II doctrine—claiming that they do not extend religious freedom to Satanists—leave an utterly unreal interpretation, which still entails what Pope Leo XIII called "the legal apostasy of society from its Divine Author."
This is precisely what Pope Pius XI warned about in his encyclical Quas Primas.
This encyclical was on the Kingship of Christ, and it should be clear that this “social reign of Christ the King” is in many ways equivalent to the liberty of the Church.
In this encyclical, Pius XI noted the following trajectory towards ruin:
The rejection of Christ’s Kingship itself, “the empire of Christ over all nations,” which leads to…
The rejection of the liberty of the Church, “the right which the Church has from Christ himself, to teach mankind, to make laws, to govern peoples in all that pertains to their eternal salvation,” which leads to…
The imposition of religious liberty and indifferentism, namely, the process by which “the religion of Christ came to be likened to false religions and to be placed ignominiously on the same level with them,” which leads to…
The subjection of the Church to “the power of the state [leaving her] tolerated more or less at the whim of princes and rulers,” which leads to…
The promotion of naturalism, “a natural religion consisting in some instinctive affection of the heart”. Which ultimately leads to…
Atheism and atheistic states, which hold that they “could dispense with God, and that their religion should consist in impiety and the neglect of God.”
