And there have always been marriages that break up.  So the question is whether it's better to have a rule that holds the couple to an ideal, or to chip away at the rule and lower the bar with the end result that there will be even more marital breakups?  It really comes down to faith in God, doesn't it?  And frankly, with the way that faith is dwindling these days, few seem to care anyway what the Church teaches.  As I said elsewhere, I think this is a guise for making unrepentant homosexual acts not sinful.  There is no united group of married couples seeking Communion to be driving this.
