CC 2386. It can happen that one of the spouses is the innocent victim of a divorce decreed by civil law; theis spouse therefore had not contravened the moral law. There is a considerable difference between a spouse who has sincerely tried to be faithful to the sacrament of marriage and is unjustly abandoned, and one who through his own grave fault destroys a canonically valid marriage.
Perhaps if Bruskewitz' canonists had made this further distinction, it would have been more helpful.
Now I see your cite.
The webpage announcement serves as a warning--consult your pastor before making any assumptions about Communion.
So? That comports quite will with 2386, does it not?
