Didymus the Blind : In the spiritual sense [this saying] is even more valid, for "young men" are those who are strong because they have the Word of God and because they have power against evil. John, for example, writes, "I write to you, young people, because you are strong and the Word of God abides in you, and you have overcome the evil one." He certainly does not write to a certain age group in a physical sense but to a soul made young, since it has "clothed [itself] with the new self." — COMMENTARY ON Ecclesiastes 335:5 Gregory the Dialogist : He shews himself to live with good heed and circumspection, who, in considering the shortness of the present life does not look to the furtherance but to the ending of it, so as to gather from the end, that all is nought that delights while it is passing. For hence it is said by Solomon, But if a man live many years and rejoice in them all, yet let him remember the time of darkness, and the days that shall be many; and when they come, the past shall be convinced of vanity. Hence again it is written, Whatsoever thou takest in hand, remember thine end, and thou shalt never do amiss. Therefore when sin tempts the mind, it is requisite that the soul should regard the shortness of its gratification, lest iniquity hurry it on to a living death, when it is plain that a mortal life is quickly speeding to an end. — Morals on the Book of Job, Book 9
