St. Christopher, a native of Chanaan, was martyred at Lycia in the Third Century. He was greatly venerated in the East. His name, which signifies “one who carries Christ”, won for him great veneration even in the city of Rome. Many statues of St. Christopher were placed at the entrance to cathedrals. He is the patron of travelers and is invoked in storm, tempest and plagues. The medal of St. Christopher is frequently attached to motor vehicles.
