Impassibility

Impassibility (from Latin in-, "not", passibilis, "able to suffer, experience emotion") describes the theological doctrine that God does not experience pain or pleasure from the actions of another being. It has often been seen as a consequence of divine aseity, the idea that God is absolutely independent of any other being, i.e., in no way causally dependent. Being affected (literally made to have a certain emotion, affect) by the state or actions of another would seem to imply causal dependence.

Some theological systems portray God as a being expressive of many (or all) emotions. Other systems, mainly in Judaism and Islam, portray God as a being that does not experience suffering or any other emotion at all. However, in Christianity there is an ancient dispute about the impassibility of God (see Nestorianism). Still, it is understood in all Abrahamic religions, including Christianity, that God is not subject to temptation or sin at all, since sin is defined as rebellion against God's loving authority and holiness. Or one could see sin as rebellion to God's will in general, and while it is conceivable that an ordinary being could "rebel" against his own better wishes, God arguably cannot since he is all-powerful and all-wise and is therefore compelled by his own nature to follow his best wishes.

The Catholic Church teaches dogmatically that God is impassible. The divine nature accordingly has no emotions, changes, alterations, height, width, depth, or any other temporal attributes. While Jesus Christ's human nature was complete, and thus Christ possessed a human body, human mind and human soul, and thus human emotions, this human nature was hypostatically united with the timeless, immutable, impassible divine nature, which retained all of its divine attributes without alteration, just as his human nature retained all of its human attributes. In Catholic doctrine, it would be erroneous and blasphemous to attribute changes or emotional states to God, except by analogy. Thus scriptural expressions which indicate "anger" or "sadness" on God's part are considered anthropomorphisms, mere analogies to explain mankind's relationship to God, who is impassible in his own nature. Some objecting to this claim assert that if God cannot have emotions, then God cannot love, which is a central tenet of Christianity. However, Catholics would point out that love is not an emotion except in a secondary sense, and is far more than simply a changeable emotion. Furthermore, the human nature of Christ expressed emotional love as well as possessing the timeless, unconditioned "agape" of God.
