There is nothing more demanding than the taste for mediocrity. Beneath its ever moderate appearance there is nothing more intemperate; nothing surer … - Henri de Lubac

Pierre Teilhard was a consistent personalist. In his youth he may well have experienced the 'fascination of the impersonal and generalized' and confused them with the universal; but as soon as he began to develop his thought, he made a complete change of direction.

[T]hough not being absolutely the same as ours, the difficulties for a Saint Peter or a Saint Paul in believing were no less strong. Nor were those of their successors, the Origens and the Cyrils , the Ambroses and the Augustines. Modern man flatters himself when he judges that the Copernican revolution or the Kantian revolution dug out a new hiatus between his thought and the thought of the Ancients. It was as hard to believe then as it is today! It was hard, for a Jewish monotheist—"Listen, Israel! Your God is one!"—to believe in the divinity of a man. It was hard to believe in the crucifixion of the Son of God. It was hard for a reasonable man, who had been able to see up close the Son of Man in his humiliation, to believe in the resurrected Christ.

It becomes increasingly clear that […] the Christian's watchword can no longer be "escape" but "collaboration". He must co-operate with God and men in God's work in the world and among humanity.
