It is […] the very opposite of a "closed society". Like its founder it is eternal and sure of itself, and the very intransigence in matters of princi… - 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 Church's method is not syncretist any more than it is naïve. Syncretism is artificial, generally the work of rulers or literary men, and presupposes declining faith. It is an insult to the living God. In the energetic language of the prophets, syncretism is fornication. In the spiritual order it is barren, like the political system or philosophy from which it springs. It lowers and vulgarizes all the elements it combines[…]. But here again the history of the Church can teach us. Christianity rejected Gnosticism, a representative of the syncretist system; but such an uncompromising boldness has not hindered her in carrying out her work of assimilation with a breadth of vision that is more clearly manifest every day.

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.
