Whether hatred of God is the greatest of sins?

Objections

Objection 1 : It would seem that hatred of God is not the greatest of sins. For the most grievous sin is the sin against the Holy Ghost, since it cannot be forgiven, according to Mt. 12:32. Now hatred of God is not reckoned among the various kinds of sin against the Holy Ghost, as may be seen from what has been said above (Question [14], Article [2]). Therefore hatred of God is not the most grievous sin.
Objection 2 : Further, sin consists in withdrawing oneself from God. Now an unbeliever who has not even knowledge of God seems to be further away from Him than a believer, who though he hate God, nevertheless knows Him. Therefore it seems that the sin of unbelief is graver than the sin of hatred against God.
Objection 3 : Further, God is an object of hatred, only by reason of those of His effects that are contrary to the will: the chief of which is punishment. But hatred of punishment is not the most grievous sin. Therefore hatred of God is not the most grievous sin.
