YEs there is one Body but your church is just one of many splinterd denomination,s. You cant divide Christ by mens religions, We are a part of His church, His body because of Him and what He did, not because of men and there religions,I simply recognize - as Christ Himself does (Matt. 16:18, John 17:20-23), that there is only ONE Body - not 50,000 or so perpetually-splintering sects all teaching different doctrines.
If you dont like it go tell Him.
Have you not read
Joh 14:5 Thomas saith unto him, Lord, we know not whither thou goest; and how can we know the way?
Joh 14:6 Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.
And so we follow Christ because
Joh 10:26 But ye believe not, because ye are not of my sheep, as I said unto you.

Joh 10:28 And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand.
Joh 10:29 My Father, which gave them me, is greater than all; and no man is able to pluck them out of my Father's hand.
and
