"The punishment of original sin is deprivation of the vision of God, but the punishment of actual sin is the torments of everlasting hell." -Pope Innocent III (Maiores Ecclesiae causas, Dz 780).
"(De malo 5, 3), such a pain of loss" (as that of the vision of God) "is compatible with a certain natural happiness. At the last judgment, when the bodies will rise to share in the punishment or reward of heaven or hell, the bodies of those who are in Limbo will also rise. Although separated from God, in which way they share the punishment of the damned in hell, they will not be tormented by remorse nor will they suffer the pain of the sense which the damned suffer forever in hell." St. Thomas Aquinas
