Relevant quote from St. Basil:
"Who is the covetous man? One for whom plenty is not enough. Who is the defrauder? One who takes away what belongs to everyone. And are not you covetous, are you not a defrauder, when you keep for private use what you were given for distribution? When some one strips a man of his clothes we call him a thief. And one who might clothe the naked and does not—should not he be given the same name?
The bread in your hoard belongs to the hungry; the cloak in your wardrobe belongs to the naked; the shoes you let rot belong to the barefoot; the money in your vaults belongs to the destitute. All you might help and do not—to all these you are doing wrong"
