Thus the moral theologians of the Western Hemisphere, in their efforts to still remain “credible” in our society, find themselves facing a difficult alternative: it seems to them that they must choose between opposing modern society and opposing the Magisterium.
…
Thus we stand before the difficult alternative: either the Church finds an understanding, a compromise with the values propounded by society which she wants to continue to serve, or she decides to remain faithful to her own values (and in the Church’s view these are the values that protect man in his deepest needs) as the result of which she finds herself on the margin of society.
…
But one cannot struggle against nature without undergoing the most devastating consequences. The sacrosanct equality between man and woman does not exclude, indeed it requires, diversity.
…
Christianity is not “our” work; it is a Revelation; it is a message that has been consigned to us, and we have no right to reconstruct it as we like or choose.
