"... those who find themselves in hell will be chastised by the scourge of love. How cruel and bitter this torment of love will be! For those who understand that they have sinned against love, undergo no greater suffering than those produced by the most fearful tortures. The sorrow which takes hold of the heart, which has sinned against love, is more piercing than any other pain. It is not right to say that the sinners in hell are deprived of the love of God… But love acts in two ways, as suffering of the reproved, and as joy in the blessed!" (St. Isaac of Syria, Mystic Treatises)
I don't disagree with the above quote, that's the greatest pain of hell. But as a traditional Catholic I don't deny other torments probably exist and that hell is a distinctly different "place." That just seems obvious from scripture.
But I will shew you whom you shall fear: fear ye him, who after he hath killed, hath power to cast into hell. Yea, I say to you, fear him. -Luke 12:5
And Abraham said to him: Son, remember that thou didst receive good things in thy lifetime, and likewise Lazareth evil things, but now he is comforted; and thou art tormented. And besides all this, between us and you, there is fixed a great chaos: so that they who would pass from hence to you, cannot, nor from thence come hither. -Luke 16:25
And whosoever was not found written in the book of life, was cast into the pool of fire. -Revelation 20:15
