I'm not sure about the Protestant acceptance of divorce/remarriage you are alluding to and how it compares/contrasts to the annulments handed out by Rome.
I was speaking of the article at the top of this thread, "Evangelicals Shift Toward Acceptance on Divorce." As for the rat of amendments, 'tis indeed a vexation and a puzzlement. There's this statistic:
"For the year 2002: of the 56,236 ordinary hearings for a declaration of nullity, 46,092 received an affirmative sentence. [Meaning there were 46,092 total annulments of Catholic marriages in 2002 worldwide.] Of these, 343 were handed out in Africa, 676 in Oceania, 1,562 in Asia, 8,855 in Europe and 36,656 in America, of which 30,968 in North America [Meaning that 66% of the world's Catholic annulments were in the US and Canada, which comprise only 6% of the world's Catholic population] and 5,688 in Central and South America.
Which makes me think the problem is, precisely, the American Catholic Church (huh! and there were those who said there is no such heresy as Americanism!)
And there'ss this statistic: "In the US: For every eight Catholic marriages, there is one annulment."
Which makes the rate of US Catholic annulments approximately 1/4 the rate of all American divorces overall.
Not that this is OK. This is not good. Not good at all.
