Because you may have thought He meant the church?
Ephesians 1:22 And hath put all things under his feet, and gave him to be the head over all things to the church, 23 Which is his body, the fulness of him that filleth all in all.
Ephesians 5:30 For we are members of his body, of his flesh, and of his bones.
1 Corinthians 12:27 Now you are the body of Christ, and members in particular.
Catholics have serious problem with that whole eating Christs flesh thing. Next thing you know they will be eating each other or something.
