John Calvin on 1 Corinthians 12:17

17. If the whole body were an eye He sets aside a foolish aiming at equality, by showing the impossibility of it. “If all the members,” says he, “desire the honor that belongs to the eye, the consequence will be, that the whole body will perish; for it is impossible that the body should remain safe and sound, if the members have not different functions, and a mutual correspondence between them. Hence equality interferes with the welfare of the body, because it produces a confusion that entails present ruin. What madness, then, would it be, should one member, instead of giving way to another, “De s’accommoder et soumettre a l’un des autres membres;” — To accommodate itself, and submit to one of the other members.” conspire for its own ruin and that of the body!”
