Pope Benedict asks, "How is it possible for a man to use his eyes in such a way that he perceives and respects the dignity of the other person and guarantees his own dignity? The drama of our times consists precisely in our capacity to look at ourselves like this -- and that is why we find it threatening to look at the other and must protect ourselves against this ... A child can open himself confidently to love if he knows he is loved, and he can develop and grow if he knows that he is followed everywhere by his parents' look of love" [Christianity and The Crisis of Cultures, 70-71].
When we forget what the Holy Father says, we are consigned to ontological sickness. Our relation to our earthly mother and father will not avail, being abbreviated, imperfect, unsatisfying. But, as the Psalmist knows in Psalm 139, if we walk in the sight of the LORD, who does not wish to find us perishing or lacking in any good, then "all manner of things shall be most well," as Julian of Norwich observed.
If we do our best, stay connected in the Sacraments, pray constantly for ourselves and every single person we meet in "I-Thou" (M. Buber) interactions, our precious time will not be wasted. Indeed, how better can our time be "spent"?
