St Christopher was a ferry man, who operated a ferry to take people across the river. He was tall, strong and handsome.
One day, the child Jesus came to him in disguise and asked to be taken across the river. St Christopher took the child Jesus across the river, and it became deeper and deeper and he held the child above the water, and called on God to help.
It was then that the child Jesus revealed himself and told him that he would always be available for help, if he were to always bear his burdens as the burdens of Christ. Hence, his name was changed to Christ-opher, which means, bearer of Christ.
He was made a saint in the early church.
