BOOK: EXCERPT: Monsters of Babylon: How the Jews Betrayed Mankind (1200 BC to 1000 AD) – Volume II – Chapter 11: The Gospels According to G_d – Matthew 19
In Matthew 19, Jesus establishes the basis for a celibate clergy and the renunciation of worldly wealth by the monks and nuns of Christianity.
Not everyone wants to, or is able to, become a monk or nun.
But those who hear such a calling, should be supported by the laity for it is only those who meditate upon God who are able to answer questions about God.
So, offering food to the monks, returns many rewards to the laity, rewards not earnable in any other way.
