Can someone point to me where St. Thomas Aquinas said that the, "greatest penalty of sin is the loss of the sense of sin"?
I heard this from Catholic Answers Live last week.
St. Thomas says in
that "death is the greatest of punishments" ("mors est maxima poenarum").
Also, he writes in Summa Theologiae II-II, q. 79 a. 4 arg. 4:
…the pain of loss which consists in being deprived of seeing God and is inflicted for the sin of omission, is a greater punishment than the pain of sense, which is inflicted for the sin of transgression…
Maybe what they meant is that sin can be the punishment of sin or that ignorance (a defect of the intellect), malice (a defect of the will), weakness, and concupiscence are effects of sin.
The Summa Theologiae and in the third book of the Summa "Contra Gentiles"
CAtholic answers (I did not hear the program) may have been paraphrasing the concept of Aquinas's view of original justice and the effect it has on our inability to recognize sin.
