Ambrose of Milan

Now there came to pass in that country a famine not of food but of good works and virtues, which is the more wretched fast. For he who departs from the word of God is hungry, because man does not live on bread alone, but on every word of God. (Matt. 4:4.) And he who departs from his treasures is in want. Therefore began he to be in want and to suffer hunger, because nothing satisfies a prodigal mind. He went away therefore, and attached himself to one of the citizens. For he who is attached, is in a snare. And that citizen seems to be a prince of the world. Lastly, he is sent to his farm which he bought who excused himself from the kingdom. (Luke 14:18.)
