Whether hatred of our neighbor is the most grievous sin against our neighbor?
Objections
❌ Objection 1 : It would seem that hatred of our neighbor is the most grievous sin against our neighbor. For it is written (1 Jn. 3:15): "Whosoever hateth his brother is a murderer." Now murder is the most grievous of sins against our neighbor. Therefore hatred is also.
❌ Objection 2 : Further, worst is opposed to best. Now the best thing we give our neighbor is love, since all other things are referable to love. Therefore hatred is the worst.
