If you do not understand either the reason why they take it seriously or the underlying topics over which they debate, might I suggest that imposing the label "arrogant" is a bit hasty?
You may suggest it. I think not, I didn't come to this opinion quickly, or after one event.
That said,
With all due respect, and with Christian charity, might I suggest that you aren't exactly accomplishing anything good by your comments earlier in the thread? Your comments seem equally arrogant to some of us, as others' may seem to you.
Fair enough. We don't always know exactly how our comments come across, and how they may differ, and we each bring our own baggage to a conversation. I can see how you might think that. We could continue to argue the finer points of religious arrogance, and the blinders of one's faith and presuppositions (on both sides) but I really don't want to do that. I fear it will lead nowhere useful for any of us. Arrogant I can sometimes be, but I'm not arrogant enough to think that my opinions on how you conduct your faith carry any weight at all in your observance of that faith.
So having gone back and forth for a bit, I'll take Scout's advice and head off in a different direction.
In the article referenced in the OP it talks about the African parts of the Anglican church pushing for the sanction, and being happy about it.
I gather from our conversations that the Episcopalians in the US are the side of this debate you (the observant orthodox Christians. Is that a decent term for you?) are least happy with. Mostly because of the inclusion open approval of gays. Is that a decent summation of this particular issue?
So, other than Africans being pretty orthodox about gays, there's not a whole lot about the rest of that culture that we would seem to welcome here in the states. Culture and religion are intertwined. Do you think that as the more third world christian denominations gain influence in the worldwide orgs, some of the less nice things might bleed over as well? Spitballing: Women still get treat pretty crappy, slavery is still a thing in Africa, churches being active in government. Stuff like that.
I wouldn't expect it to come over here like Ebola or anything but worldwide governing churches have been known to sway politically as their populations change. Or do you think that would lead to more schisims?
