At the end of n.93, Pope Francis quotes Henri de Lubac:
..... if [spiritual worldliness] were to seep into the Church, “it would be infinitely more disastrous than any other worldliness which is simply moral”.The quotation is taken from the very end of de Lubac's book translated into English as The Splendor of the Church. The full passage from which the quotation is taken provides an instructive commentary on this section of Evangelii Gaudium. It comes at the end of a chapter in which de Lubac has presented the analogy between the figure of Mary and the Church, as de Lubac points out that we who are members of the Church do not show forth the light that is seen in our Lady.
.... the greatest danger we are to the Church, the most subversive temptation, the one that is ever and insidiously reborn when all the rest are overcome, and even strengthened by those victories, is what Abbot Vonier called the temptation to "worldliness of mind ... the practical relinquishing of other-worldliness, so that moral and even spiritual standards should be based, not on the glory of the Lord, but on what is the profit of man; an entirely anthropocentric outlook would be exactly what we mean by worldliness. Even if men were filled with every spiritual perfection, but if such perfection were not referred to God (suppose this hypothesis to be possible) it would be unredeemed worldliness". [De Lubac here references Abbot Vonier's The Spirit and the Bride.]
If this spiritual worldliness were to invade the Church and set to work to corrupt her by attacking her very principle, it would be something infinitely more disastrous than any worldliness of the purely moral order - even worse than the hideous leprosy that at certain moments in history inflicts so cruel a disfigurement on the Bride; when religion seems to set up the scandalous "in the very sanctuary itself ..."
None of us is wholly immune to this sort of evil....Pope Francis' judgement offered in n.97 is strong:
Those who have fallen into this worldliness look on from above and afar, they reject the prophecy of their brothers and sisters, they discredit those who raise questions, they constantly point out the mistakes of others and they are obsessed by appearances. Their hearts are open only to the limited horizon of their own immanence and interests, and as a consequence they neither learn from their sins nor are they genuinely open to forgiveness. This is a tremendous corruption disguised as a good.POSTSCRIPT
I am still on the hunt for the origins of that phrase "self-absorbed promethean neopelagianism".
