There is another form of enmity or hatred that runs not to blows but to words. Herein is evil, not because of any bodily injury wrought, of which there is none, but because of the diabolical spirit that manifests itself, a spirit reproved by God and which, in given circumstances, is ready to resort to physical injury and even to the letting of blood. There can be no doubt that hatred in itself is forbidden by this commandment, for "whosoever hateth his brother is a murderer," according to St. John. It matters little, therefore, whether such hatred be in deeds or in words; the malice is there and the sin is consummated. A person, too weak to do an enemy bodily harm, may often use his or her tongue to better effect than another could his fists, and the verbal outrage thus committed may be worse than a physical one. It is not even necessary that the spirit of enmity show itself at all on the outside for the incurring of such guilt as attends the violation of this commandment. It is sufficient that it possess the soul and go no farther than a desire to do harm. This is the spirit of revenge, and it is none the less sinful in the eyes of God because it lacks the complement of exterior acts. It is immoral to nourish a grudge against a fellow-man. Such a spirit only awaits an occasion to deal a blow, and, when that occasion shows itself, will be ready, willing and anxious to strike. The Lord refuses the gifts and offerings and prayers of such people as these; they are told to go and become reconciled with their brother and lay low the spirit that holds them; then, and only then, will their offerings be acceptable. Even less than this suffices to constitute a breach of the Fifth Commandment. It is the quality of such passions as envy and jealousy to sometimes be content with the mere thought of injury done to their object, without, even going so far as to desire to work the evil themselves. These passions are often held in check for a time; but, in the event of misfortune befalling the hated rival, there follows a sense of complacency and satisfaction which, if entertained, has all the malice of mortal sin. If, on the contrary, the prosperity of another inspire us with a feeling of regret and sadness, which is deliberately countenanced and consented to, there can be no doubt as to the grievous malice of such a failing.
