"There are some conciliar texts that are clearly in conformity with Tradition and pose no problem: I am thinking of Lumen Gentium, but also of other documents such as those on priestly formation and seminaries. Then there are ambiguous texts, which nevertheless can be correctly “interpreted” in a certain way according to the previous Magisterium. But there are also texts that are frankly in contradiction with Tradition and cannot be “integrated” in any way: the Declaration on Religious Freedom, the Decree on Ecumenism, and the one on the Liturgy. Here agreement becomes impossible. [...] It is the Declaration on Religious Freedom that is the real bone of contention, because the introduction of this liberal principle into the Church has led to other errors. The break with Tradition in this case is evident: eleven Popes, from Pius VI to Pius XII, condemned liberalism, and the Council approved it. No one can convince me that there is no contradiction."
