For God, He said, gave us understanding, that we might chase away all ignorance, and have the right judgment of things, and that using this as a kind of weapon and light against all that is grievous or hurtful, we might remain in safety. But we betray the gift for the sake of things superfluous and useless.
St. John Chrysostom
Homily 20 and 21 on Matthew 6, 4th Century
A brother, more thrifty than covetous, ... left behind him at his death a hundred pieces of money which he had earned by weaving linen. ... a council was held as to what should be done [with the money] ... However, Macarius, Pambo, Isidore and the rest of those called fathers, speaking by the Spirit, decided that they should be interred with their owner, with the words: "Thy money perish with thee."
St. Jerome
Letter 22 to Eustochium
There is none who has tasted God's richness and does not regard money as dung; none who has enjoyed the company of angels, none who has gotten drunk with their rapture, none who has shared their secrets, who does not hate the world and its intrigues. There is none whom the love of Christ has pierced who can any longer bear the filth of abominable lust; none whose mind has been captivated by God's beauty who can be captivated by any passions of this world; none who has found God and known Him who has not proudly forgotten this world. These precious stones he collects and keeps in the treasure of his heart.
St. John of Dalyatha
Homily on the Greatness of the Rank of Angels, Unknown
The truth is that people are frightened of being poor because they have no faith in Him who promised to provide all things needful to those who seek the kingdom of God (cf. Matt. 6:33). It is this fear that spurs them, even when they are endowed with all things, and it prevents them from ever freeing themselves from this sickly and baneful desire. They go on amassing wealth, loading themselves with a worthless burden or, rather, enclosing themselves while still living in a most absurd kind of tomb.
