And he said to them, "Where you enter a house, stay there until you leave the place. And if any place will not receive you and they refuse to hear you, when you leave, shake off the dust that is on your feet for a testimony against them."

Mark 6:10-11

"Great are those two gifts, wisdom and continence: wisdom, forsooth, whereby we are formed in the knowledge of God; continence whereby we are not conformed to this world."

– St. Augustine
