I would agree to that to a certain extent. Ultimately we can't know or judge who is a member of God's church...who has the spirit of God. We're not capable and Christ made this clear in the parable of the wheat and tare. However we can band together with others of like minds in organizations to combine resources to fulfill the commission that Christ gave his disciples. Under those circumstances we make the good faith assumption that we've banded together with fellow Christians and we make that discernment based on the spiritual fruits we perceive and the love we show to one another.
It’s not even in operation. It’s not here yet. Men who would be king and wear robes and mitres like to think it is here, and ecclesiastics of ALL sorts and denominations like to make it something they can have their petty authority in, BUT IT’S NOT EVEN HERE ON EARTH AT ALL.
