“"He that saith he is in the light,"-in the light, he means in the truth,-"and hateth," he says, "his brother." By his brother, he means not only his neighbour, but also the Lord. For unbelievers hate Him and do not keep His commandments. Therefore also he infers: "He that loveth his brother abideth in the light; and there is none occasion of stumbling in him."”
