For a spiritual and metaphysical crisis, only a remedy of the same nature is appropriate. - Henri de Lubac

The Church, trusting in the Holy Spirit that leads her, trusts also all the peoples that she comes to free. That is no sign of naïveté on her part. She […] knows […] that all men are one in community of their divine origin and destiny; and that suffices to give her confidence in face of all the theories engendered by pride and egoism.[…] Besides, does not the only efficacious way to bring out the hidden truth and to avoid extinguishing the good that would break forth lie in a systematic desire to study sympathetically those forms of thought that are most remote from us, and in this study to pay particular attention to privileged cases, however rare they may be? It is at its highest reaches that humanity must be understood; the plains—or the depressions—will always be explored soon enough.

The fear of falling a prey to error must never prevent us from getting to the full truth. To overstep the limit, to go beyond, would be to err through excessive daring; but there are also errors of timidity which consist precisely in stopping short, never daring to go any further than half-truths.<p>Love of truth never goes without daring. And that is one of the reasons why truth is not loved.

Decadence, instability, disintegration, corruption, reversal of attitude, all that arises through the simple fact of one's going on existing without self-criticism, self-renewal, constant self-adaptation, without letting anything in one die, through the simple fact of gradually settling down in the vantage point one occupies, the good conscience one enjoys. Such is the permanent danger of all spiritual life. It is an inevitable deterioration which can only be overcome—and painfully at that—by a watchful mustering of strength—unless it be effortlessly vanquished by a wonderful gift of grace.…<p>Whence the necessity of paradox: or rather the perpetual flavor of paradox that truth has, when it is freshly expressed, for the man who clings to a truth when it is in the process of turning into a lie.
