In St. Vincent’s life, bringing God’s peace to others was a constant call: he reminded his colleagues that “God’s Spirit is a spirit of peace, a gentle inspiration that slips in without any commotion. Everything He does is always followed by calmness and gentleness; He is the God of peace and union. He cannot tolerate any disturbance or division.” (Saint Vincent de Paul, Correspondence, Conferences, Documents, Volume XII, Letter 214)
Vincent was a tireless missionary of God’s peace. He preached with actions and words that we are called to share God’s peace with our brothers and sisters. Vincent understood, as Jesus did, that he was called to bring God’s peace not to the wealthy and comfortable, but to the poor, the stranger, the one who was marginalized because he or she is different from others. These, the most vulnerable are the face of Christ in the world, and they must receive God’s peace.
