There is no way in hell they would adopt those sex policy changes. No way, no how, not in a hundred years. That's where I draw the line. The only thing I might see them lightening up on is what a married couple do with each other behind closed doors.
I do see them making a lot of the other changes, though. Definitely regarding some of the "soft holidays" and birthdays. I definitely also see them simplifying prophetic teachings, since their entire dogma has been dumbed down massively already over the past 20 years.
Yes on tattoos and piercings. Those things are fully accepted in the younger generations, being mainstream. You can have piercings now anyway and it's not going to get you DFd. Maybe restricted from "priveleges," but they're not that big a deal, so it isn't a stretch that they'd eventually give up on it completely.
I don't understand the paragraph on the "Evil Slave" at all. Not sure what the message on that is.
Yes on all the publishing/assembly changes.
And yes on the dynamic changing with the CO and elders. If they want to appoint more elders and MSs (the "worker bees" of the org), their standards will have to come down (as if they aren't low enough already). And if that's the case, they'd need the COs to be proactively involved in appointments and take on more responsibility in that respect. Interesting about the permanence of the CO in a given region. Almost reminds me of the role of a bishop in the catholic and orthodox churches.
