118 But, in truth, hatred of God and of those who lawfully act in His place is the greatest kind of sin that can be committed by man created in the image and likeness of God and destined to enjoy His perfect and enduring friendship for ever in heaven. Man, by hatred of God more than by anything else, is cut off from the Highest Good and is driven to cast aside from himself and from those near to him whatever has its origin in God, whatever is united with God, whatever leads to the enjoyment of God, that is, truth, virtue, peace and justice.(117)
