The Good Samaritan, is a parable f Christ, which was recorded by St. Luke (10:30-35). One day a man, travelling from Jerusalem to Jericho, was attacked by robbers, who beat, bound and left him by the road. Many respectable people passed by, not offering help. A Samaritan (a member of a people despised by the Hebrews) saw the wounded man and helped him: treated his wounds, took him to an inn, left him there until full recovery, and paid the bill.
