Jerome : "Vanity of vanities says Ecclesiastes; all is vanity." Then after the description of man's death, he goes back to the beginning of his book, saying, "vanity of vanities, says Ecclesiastes, all is vanity" [Eccl. 1,2.]. For all toil of mortal men, which is argued all through the books, is pertinent here, so that dust returns to the earth, and the spirit returns to the place, whence it was taken, it is a great vanity in this world to toil and obtain nothing for the future from it. — Commentary on Ecclesiastes John Chrysostom : Such is "vanity of vanities," your splendid buildings, your vast and overflowing riches, the herds of slaves that bustle along the public square, your pomp and vainglory, your high thoughts, and your ostentation. For all these are vain; they came not from the hand of God, but are of our own creating. But why then are they vain? Because they have no useful end. Riches are vain when they are spent upon luxury; but they cease to be vain when they are "dispersed and given to the needy." But when thou hast spent them upon luxury, let us look at the end of them, what it is;—grossness of body, flatulence, pantings, fullness of belly, heaviness of head, softness of flesh, feverishness, enervation; for as a man who shall draw into a leaking vessel labors in vain, so also does the one who lives in luxury and self-indulgence draw into a leaking vessel. — HOMILIES ON Ephesians 12 John Chrysostom : Hear what Solomon says, who knew the present world by actual experience. "I builded me houses, I planted me vineyards, I made me gardens, and orchards and pools of water. I gathered me also silver and gold. I gat myself men-singers, and women-singers, and flocks, and herds." There was no one who lived in greater luxury, or higher glory. There was no one so wise or so powerful, no one who saw all things so succeeding to his heart's desire. What then? He had no enjoyment from all these things. What after all does he say of it himself? "Vanity of vanities, all is vanity." Vanity not simply but superlatively. Let us believe him, and lay hold on that in which there is no vanity, in which there is truth; and what is based upon a solid rock, where there is no old age, nor decline, but all things bloom and flourish, without decay, or waxing old, or approaching dissolution. Let us, I beseech you, love God with genuine affection, not from fear of hell, but from desire of the kingdom. For what is comparable to seeing Christ? Surely nothing! What to the enjoyment of those good things? Surely nothing! Well may there be nothing; for "eye hath not seen, nor ear heard, neither have entered into the heart of man the things which God hath prepared for them that love Him." — HOMILIES ON 1 TIMOTHY 15
