If the whole body were an eye, where would be the hearing? If the whole were hearing, where would be the smelling?
All Commentaries on 1 Corinthians 12:17 Go To 1 Corinthians 12
John Chrysostom
AD 407
Thus, because, having fallen upon the difference of the members, and having mentioned feet, and hands, and eyes, and ears, he led them to the consideration of their own inferiority and superiority: see how again he consoles them, intimating that so it was expedient: and that their being many and diverse, this especially causes them to be a body. But if they all were some one, they would not be a body. Wherefore, he says, If they were all one member, where were the body? This however, he mentions not till afterwards; but here he points out also something more; that besides the impossibility of any one being a body, it even takes away the being of the rest.
For if the whole were hearing, where were the smelling, says he.
4. Then because after all they were yet disturbed: that which he had done above, the same he does also now. For as there he first alleged the expediency to comfort them and afterwards stopped their mouths, vehemently saying, But all these works the one and the same Spirit, dividing to each one man severally even as He will: so also here having stated reasons for which he showed that it was profitable that all should so be, he refers the whole again to the counsel of God.
