1 Corinthians 13:1

And see whence he first begins; from that which was marvellous in their eyes and great, the gift of tongues. And in bringing forward that gift, he mentions it not just in the degree they had it in, but far more. For he did not say, "if I speak with tongues," but, "If I speak with the tongues of men,-" What is, "of men?" Of all nations in every part of the world. And neither was he content with this amplification, but he likewise uses another much greater, adding the words, "and of angels,-and have not love, I am become sounding brass, or a clanging cymbal." Dost thou see to what point he first exalted the gift, and to what afterwards he lowered and cast it down? For neither did he simply say, "I am nothing," but, "I am become sounding brass" a thing senseless and inanimate. But how "sounding brass?" Emitting a sound indeed, but at random and in vain, and for no good end. Since besides my profiting nothing, I am counted by most men as one giving impertinent trouble, an annoying and wearisome kind of person. Seest thou how one void of love is like to things inanimate and senseless? Now he here speaks of the "tongues of angels," not investing angels with a body, but what he means is this: "should I even so speak as angels are wont to discourse unto each other, without this I am nothing, nay rather a burden and an annoyance." Thus (to mention one other example) where he saith, "To Him every knee shall bow, of things in heaven and things on earth, and things under the earth," he doth not say these things as if he attributed to angels knees and bones, far from it, but it is their intense adoration which he intends; also here he calls it "a tongue" not meaning an instrument of flesh, but intending to indicate their converse with each other by the manner which is known amongst us.
