That organization has led the PCUSA where?
Believe me, I know all too well where it has led.
Nothing is perfect. My point is that the presbyterian system of church governing seems to be optimal, just like our representative republic is optimal. Both come equipped with a system of checks and balances that hopefully keeps the ship afloat and on an even keel.
The PCUSA has floundered since NOT adhering to the basic system set in place which is ALWAYS first and foremost to be faithful to the word of God. It wasn't. And so it has devolved.
Does our system of government or our system of church structure work perfectly? Nope. But what system works better? That's the question. Not to mention I think this system is outlined in the New Testament.
