At the time of our Savior, the Pharisees had restrained the meaning of the word "neighbor" to those of their own nation, or to their own friends; holding, that to hate their enemy was not forbidden by the law, Mt 5:43. But our Savior informed them that the whole world was neighbors; that they ought not to do to another what they would not have done to themselves; and that this charity extended even to enemies. See the beautiful parable of the Good Samaritan, the real neighbor to the distressed, Lu 10:29.
