Two category shifts identified: from 'belonging in Christ' to 'representing Christ' to 'any function'

Mike identifies two category shifts in Westfall's argument: (1) From 'belonging to Christ' to 'representing Christ' — these are different issues, and Paul does not discuss 'representing Christ' in Galatians. (2) From 'representing Christ' to 'representing Christ in any function' — a massive expansion. The conclusion ('women can represent Christ in any function') comes out of nowhere relative to what Galatians actually discusses.
