No man can serve two masters: for either he will hate the one, and love the other; or else he will hold to the one, and despise the other. You cannot serve God and mammon.
All Commentaries on Matthew 6:24 Go To Matthew 6
Jerome
AD 420
“Mammon,” - riches are so termed in Syriac. Let the covetous man who is called by the Christian name, hear this, that he cannot serve both Christ and riches. Yet He said not, he who has riches, but, he who is the servant of riches. Forhe who is the slave of money, guards his money as a slave; but he who has thrown off the yoke of his slavery, despenses them as a master.
