Dialogue doesn't work with the devil; the only defense is the word of God, humility and meekness, especially in response to his works of hatred and persecution, Pope Francis said. "Humility and meekness: These are the weapons that the prince of the world, the spirit of the world does not tolerate, because he makes proposals for worldly power, proposals of vanity, proposals for riches," he said in his daily morning Mass homily. The pope celebrated Mass in the chapel of the Domus Sanctae Marthae, where he lives, with members of the Swiss Guard, including their commander, Col. Daniel Anrig. In his homily, the pope talked about the origin of hatred and how Jesus told his disciples of the spite and persecution awaiting them, as told in the day's reading from chapter 15 of the Gospel according to St. John. "Remember the word I spoke to you, 'No slave is greater than his master.' If they persecute me, they will also persecute you," he cited from the Gospel.
