"St. Francis taught his companions to use the greeting: The Lord give you peace!
When you proclaim peace by your words, he told them, you must carry an even greater peace in your hearts. Let no one be provoked to anger by you, or be scandalized, but let your gentleness encourage all men to peace, good will and mutual love. For our calling is to heal the wounded, to tend the maimed and to bring home those who have lost their way."
