:: PCUSA is Presbyterian if a member does something that can be considered ‘cool’ ::
Perfect!
Especialy if you apply the Obamugabe concept of “cool”.
Well, PCUSA was less looey back when Buzz did this. I guess if he’d had a capsule-mate who was also a believing Christian of any denomination that did not object, they could have shared it and made it official. But it sounds like it was the intention that counted. No word as to whether his co-congregants synchronized a communion on the ground to his partaking.
