“Just as that which is lukewarm induces vomiting in those who take it in, so also he says, I will vomit you out through the word of my mouth into eternal destruction, as though you were rotten food. For mixing together the seed of the divine word with the thistles of wealth, you have become unaware of your poverty in spiritual matters and of the blindness of your spiritual eyes and of your nakedness in good works.
If you wish to be rich, he says, with a zealous intent and a willing heart obtain from me, who makes rich, gold that has been purified in fire, namely, the word of teaching that is made brilliant in the fire of temptations. And through this you will have in your heart a treasure that is secure, and you will wear the bright stole of virtue, through which the nakedness, which has come to you by sin, will be clothed. The salve is certainly poverty. For, if “gifts make blind the eyes who see,” then certainly that which is incorruptible will open them.”
Andrew of Caesarea (7th century) in Commentary on the Apocalypse 3.16-18. MTS 1 Sup 1.43-44, cf. Sirach 20:29.
