For the body also is not one member, but many. If the foot should say, because I am not the hand, I am not of the body; is it therefore not of the body? And if the ear should say, because I am not the eye, I am not of the body; is it therefore not of the body? If the whole body were the eye, where would be the hearing? If the whole were hearing, where would be the smelling? But now God hath set the members every one of them in the body as it hath pleased him. And if they all were one member, where would be the body? But now there are many members indeed, yet one body. And the eye cannot say to the hand: I need not thy help; nor again the head to the feet: I have no need of you. Yea, much more those that seem to be the more feeble members of the body, are more necessary. And such as we think to be the less honourable members of the body, about these we put more abundant honour; and those that are our uncomely parts, have more abundant comeliness. But our comely parts have no need: but God hath tempered the body together, giving to that which wanted the more abundant honour, that there might be no schism in the body; but the members might be mutually careful one for another. And if one member suffer any thing, all the members suffer with it; or if one member glory, all the members rejoice with it.
-- 1 Corinthians 12:12-26
For no man ever hated his own flesh, but nourisheth and cherisheth it, as also Christ doth the church.
-- Ephesians 5:29
