1 Corinthians 12:21

Having checked the envy of those in lower rank, and having taken off the dejection which it was likely that they would feel from greater gifts having been vouchsafed to others, he humbles also the pride of these latter who had received the greater gifts. He had done the same indeed in his discourse also with the former. For the statement that it was a gift and not an achievement was intended to declare this. But now he doth it again even more vehemently, dwelling on the same image. For from the body in what follows, and from the unity thence arising, he proceeds to the actual comparison of the members, a thing on which they were especially seeking to be instructed. Since there was not so much power to console them in the circumstance of their being all one body, as in the conviction that in the very things wherewith they were endowed, they were not left greatly behind. And he saith, "The eye cannot say to the hand, I have no need of thee: or again the head to the feet, I have no need of you." For though the gift be less, yet is it necessary: and as when the one is absent, many functions are impeded, so also without the other there is a maim in the fulness of the Church. And he said not, "will not say," but "cannot say." So that even though it wish it, though it should actually say so, it is out of the question nor is the thing consistent with nature. For this cause having taken the two extremes, he makes trial of his argument in them, first in respect of the hand and the eye, and secondly, in respect of the head and feet, adding force to the example. For what is meaner than the foot? Or what more honorable and more necessary than the head? For this, the head, more than any thing, is the man. Nevertheless, it is not of itself sufficient nor could it alone perform all things; since if this were so, our feet would be a superfluous addition.
