those are words from my post. why are your claiming them as yours? according to what you've posted you are contradicting yourself and asking questions that you can't answer.it is not an institution. It is all believers, His family, His church. who taught about the body of Christ? what does scripture teach about it?
the bible says the church is the body/bride of christ (ephesians 5).
scripture says it is one lord, one faith, and one baptism (ephesians 4)
