In 1980 a national magazine carried an unusual story. A man returned to his car, which was parked outside a large shopping centre. Lying on the front seat was a note: “Dear Sir or Madam: “I fully intended to steal your car until I noticed the ‘Peace-Be-to-You’ sticker. It made me pause and reflect. I reasoned that if I did steal your car, you certainly would not be at peace, and on the other hand, I felt I would not be at peace either, as this was my first ‘job.’ “So, ‘peace be to you’ and to me. Drive carefully and next time lock your car.’’ The note was signed: “A Would-Be Car Thief.’’ That unusual story illustrates the instruction Jesus gave his disciples in today’s gospel: “Whenever you go into a house, first say, ‘Peace be with this house. If a peaceful – loving person lives there, let your greeting of peace remain on him; if not, take back your greeting of peace.” When the Bible uses the word peace, it uses it in four different senses. First, it uses it in a military sense – to indicate an absence of war between nations, and then we say the nations are at peace.’’ Second, it uses it in a personal sense – to indicate a feeling of personal well-being and then we say: “We are at peace with ourselves.’’ Third, the Bible uses the word peace in a religious sense – to indicate a right relationship between God and then we say, “We are at peace with God.’’ Lastly, the Bible uses the word peace to indicate a state in which everyone on earth is at peace with God, neighbour, and self. This is what we mean by the “peace of Christ.’’ This is what Jesus meant when he said, “Peace is what I leave with you; it is my own peace that I give you”. It is this peace that Jesus instructed his disciples to carry into the world. It is this peace that Jesus instructs us to carry into our world. We are to be instruments by which the peace of Christ is to be extended to every individual in every nation on earth. Are we ambassadors of peace?  Do I bring peace or dissension wherever I go?  Do I bring goodness or unease?  Do I bring good cheer or gloom? We are called to evangelise. Actions speak louder than words. We can close with the beautiful peace prayer of St. Francis. ‘Lord, make me an instrument of your peace, where there is hatred let me sow love; where there is injury, pardon; where there is doubt, faith; where there is despair, hope; where there is darkness, light; and where there is sadness, joy. Grant that I may not so much seek to be consoled as to console; to be understood as to understand, to be loved as to love; for it is in giving that we receive; it is in pardoning that we are pardoned; and it is in dying that we are born to eternal life.
