We are separated from one ...

We are separated from one another by an unbridgeable gulf of otherness and strangeness which resists all our attempts to overcome it by means of natural association or emotional or spiritual union. There is no way from one person to another. However loving and sympathetic we try to be, however sound our psychology however frank and open our behaviour we cannot penetrate the incognito of the other man, for there are no direct relationships, not even between soul and soul. Christ stands between us, and we can only get into touch with our neighbors through Him.

Whenever the Psalter is abandoned, an incomparable treasure is lost to the Christian church. With its recovery will come unexpected power.
