Many thanks for the blog, Fr. Gregory, and the subsequent thoughts.
Perhaps key here is the notion of repentance?
The woman taken in adultery was not told that since no one else condemned her she was 'fine' and should continue to explore 'alternative life-styles', she was told to sin no more. If we are not conscious of our sin, then we cannot repent; if we do repent and try to follow that through, then the forgiveness of God's Church is part of the way in which we try not to repeat our sin; if that sin lies on us, unforgiven even though we repent of it, that is hardly conducive to spiritual recovery. Long before psychol-analysis, Christianity understood the need to 'own' one's shortcomings, admit to them and try to move beyond them.
The Church is, indeed, a hospital where all may find the cure for what ails them; but we need to enter that place and undertake the treatment.
In this is love, not that we loved God, but that He loved us and sent His Son to be the propitiation for our sins. (1 John 4:10)
