4. That is, though I had ability to teach and to preach with power beyond that of any man or angel, with words of perfect charm, with truth and excellence informing my message--though I could do this, "but have not love [charity]," and only seek my own honor and profit and not my neighbor's, "I am become sounding brass, or a clanging cymbal." In other words, "I might, perhaps, thereby teach others something, might fill their ears with sound, but before God I would be nothing." As a clock or a bell has not power to hear its own sound, and does not derive benefit from its stroke, so the preacher who lacks love cannot himself understand anything he says, nor does he thereby improve his standing before God. He has much knowledge, indeed, but because he fails to place it in the service of love, it is the quality of his knowledge that is at fault. 1 Cor 8, 1-12. Far better he were dumb or devoid of eloquence, if he but teach in love and meekness, than to speak as an angel while seeking but his own interests. "And if I have the gift of prophecy." 5. According to chapter 14, to prophesy is to be able, by the Holy Spirit's inspiration, correctly to understand and explain the prophets and the Scriptures. This is a most excellent gift. To "know mysteries" is to be able to apprehend the spiritual meaning of the Scriptures, or its allegorical references, as Paul does where (Gal 4, 24-31) he makes Sarah and Hagar representative of the two covenants, and Isaac and Ishmael of the two peoples--the Jews and the Christians. Christ does the same (Jn 3, 14) when he makes the brazen serpent of Moses typical of himself on the cross; again, when Isaac, David, Solomon and other characters of sacred history appear as figures of Christ. Paul calls it "mystery"--this hidden, secret meaning beneath the primary sense of the narrative. But "knowledge" is the understanding of practical matters, such as Christian liberty, or the realization that the conscience is not bound. Paul would say, then: "Though one may understand the Scriptures, both in their obvious and their hidden sense; though he may know all about Christian liberty and a proper conversation; yet if he have not love, if he do not with that knowledge serve his neighbor, it is all of no avail whatever; in God's sight he is nothing."
