It's not a good idea. It's an evil idea, straight out of Hell, and it does nothing but encourage adulterers, homosexuals, etc. that their sinful and unrepentant lifestyles may be "blessed" with no confession or desire to ammend one's life.
Instead of drawing these people back to God, it's drawing them straight into the depths of Hell.
You can't bless sin. Period.
I said to draw people in irregular and gay marriages back into the Church and a relationship with God is a kernel of a good idea but that this document which waters down truth is not a good idea.
