John of Damascus — on Eccl 1:14 (BARLAAM AND JOSEPH 12:109-10)

“So, following the teachings of these blessed saints, we utterly renounce these corruptible and perishable things of life, wherein may be found nothing stable or constant, or that continues in one stay. But all things are vanity and vexation of spirit, and many are the changes that they bring in a moment, for they are slighter than dreams and a shadow, or the breeze that blows the air. Small and short-lived is their charm, that is after all no charm, but illusion and deception of the wickedness of the world; which world we have been taught to love not at all but rather to hate with all our heart. Yes, and truly it is worthy of hatred and abhorrence; for whatsoever gifts it gives to its friends, these in turn in passion it takes away and shall hand over its victims, stripped of all good things, clad in the garment of shame, and bound under heavy burdens, to eternal tribulation. And those again whom it exalts, it quickly abases to the utmost wretchedness, making them a footstool and a laughing stock for their enemies. Such are its charms, such its bounties.”
