In Ephesians 4:4-6 there are seven ones listed: "There is one body, and one Spirit, even as you were called in one hope of your calling; one Lord, one faith, one baptism, one God and Father of all who is above all, and through all, and in you all." Just as there is only one God and only one Lord we also see there is only one body. The Bible says there is only one body; so what is this one body? In Ephesians 1:21-22 we find out what this one body is, "And He put all things under His feet, and gave Him to be the head over all things to the church, which is His body." Here we see that the Bible says the church is the body. So if there is only one body and the one body is the church, then there can only be one church that belongs to the Lord.
