18. Imagine for a moment, and give to the eye the power to withdraw the understanding from the head, the sense of hearing from the ears, the power of thought from the mind, the sense of smell from the nose, the sense of taste from the mouth, and then to assume them itself, would it not at once destroy the whole order of nature? Wherefore the Apostle says well: “If the whole body were an eye, where were the hearing? If the whole were hearing, where were the smelling?” 1 Cor. xii. 17. So, then, we are all one body, though with many members, all necessary to the body. For no one member can say of another: “I have no need of thee.” For those members which seem to be more feeble are much more necessary and require greater care and attention. And if one member suffers, all the members suffer with it. 1 Cor. xii. 26.
