[The] self is not by nature evil, and the fact that it is unsubstantial is not to be imputed to it as some kind of crime. It is afflicted with metaphysical poverty: but all that is poor deserves mercy. So too our outward self: as long as it does not isolate itself in a lie, it is blessed by the mercy and the love of Christ. Appearances are to be accepted for what they are. The accidents of a poor and transient existence have, nevertheless, an ineffable value. They can be transparent media in which we apprehend the presence of God in the world. It is possible to speak of the exterior self as a mask: to do so is not necessarily to reprove it. The mask that each man wears may well be a disguise not only for that man’s inner self but for God, wandering as a pilgrim and exile in His own creation.
