Monomakhos, a web-log I don't particularly like, quite frankly, posted a piece about OCALaity's resolutions that they are submitting at the All-American Council this fall. The author's intro text says, "All are well aware of the continued assault on traditional marriage due to fornication, adultery, divorce, and same-sex unions." Emphasis added. I do like that he included divorce in this list.
The resolutions, however, do not contain the word "divorce" at all and only allude to it. It is of course true that, in certain circumstances, the Church allows divorce and remarriage. However, I would certainly argue that divorce is a far greater threat to "traditional marriage" than "same-sex unions" - though certainly far less than fornication and adultery - and therefore deserves at least an explicit mention in any resolution about the "sanctity of marriage". If George Michalopoulos can find room in the intro text on his web-log for the word, I'm sure the actual resolutions can as well. Divorce is the only thing on George's list, after all, that will end a "traditional marriage". I realize it's tricky to mention appropriately, but if you're going to tackle tough subjects, you have to actually tackle them. Otherwise, it's just political posturing.
EDIT: Of course, the big issue is not so much divorce but remarriage after divorce. If somebody divorces and remains celibate perpetually, there's not much to object to. However, neither Michalopoulos nor the resolutions refer to remarriage after divorce and only Michalopoulos mentions divorce.
