There’s an interesting article on Patheos’ “Unfundamentalist Christians” blog by Randall Rauser, which I strongly suggest you read before reading further.
Rauser could also have pointed out that the granddaddy of Western Theology, Thomas Aquinas, wrote as an answer to question 94 of his “Summa Theologia”:-
94. THE SAVED AND THE DAMNED
1. The sufferings of the damned will be perfectly known to the saints or blessed in heaven, and will only make them the more thankful to God for his great mercy towards themselves.
2. There can, however, be no pity in the saints with reference to the damned. For, on the other hand, they know that the damned are suffering what they chose and still perversely choose. On the other hand, pity is painful in the one who experiences it, and there can be nothing painful in heaven.
3. The blessed are in full conformity with the will of God who wills justice. The saints rejoice in the accomplishment of God’s justice. To this extent it can be said that they joy in the pains of the damned.
Rauser (to my mind entirely reasonably) asks how we can see holiness in individuals in this life as involving increased compassion for others, but think that the summit of holiness, presumably reached by being “saved” and thus one of the blessed in heaven could mean the complete absence of compassion for others.
To my thinking, this is the result of the miscegenation of Judaism and subsequently Christianity with Greek philosophical ideas, in this case the deduction that God must be “impassible”, i.e. not moved by passions. There is a decent article on Aquinas’ position at Helms Deep, which (inter alia) attempts to dispel the idea that this means the same as “impassive” (i.e. unfeeling) and, to quote, the idea that “An impassible/impassive God is said to exhibit psychotic unconcern.”
Aquinas also uses the same set of principles, arguing from God’s perfections; God must be perfectly loving, pure, wise, holy and just, to argue that God cannot be angry or jealous (both of which scripture ascribes to God repeatedly) nor can he repent (as scripture says he does on several occasions, notably in the book of Jonah), as these would detract variously from Godly perfections, as would (for example) pity or sadness (again, both ascribed to God in scripture).
My perhaps naive conclusion is that the “God” described by Aquinas (and by most of the Western traditions of theology up to and including the evangelicals of today) is not the God described in the Bible – but this “God” is one who exhibits psychotic unconcern.
And not one fit for worship.
