Whether after the resurrection every one will know what sins he has committed?

❌ Objection 1 : It seems that after the resurrection everyone will not be able to know all the sins he has committed. For whatever we know, either we receive it anew through the senses, or we draw it from the treasure house of the memory. Now after the resurrection men will be unable to perceive their sins by means of sense, because they will be things of the past, while sense perceives only the present: and many sins will have escaped the sinner's memory, and he will be unable to recall them from the treasure house of his memory. Therefore after rising again one will not be cognizant of all the sins one has committed.

❌ Objection 2 : Further, it is stated in the text (Sent. iv, D, 43), that "there are certain books of the conscience, wherein each one's merits are inscribed." Now one cannot read a thing in a book, unless it be marked down in the book: and sin leaves its mark upon the conscience according to a gloss of Origen on Rm. 2:15, "Their conscience bearing witness," etc. which mark, seemingly, is nothing else than the guilt or stain. Since then in many persons the guilt or stain of many sins is blotted out by grace, it would seem that one cannot read in one's conscience all the sins one has committed: and thus the same conclusion follows as before.

❌ Objection 3 : Further, the greater the cause the greater the effect. Now the cause which makes us grieve for the sins which we recall to memory is charity. Since then charity is perfect in the saints after the resurrection, they will grieve exceedingly for their sins, if they recall them to memory: yet this is impossible, seeing that according to Apoc. 21:4, "Sorrow and mourning shall flee away from them." [*The quotation is from Is. 35:10. The text of the Apocalypse has: "Nor mourning, nor crying, nor sorrow shall be any more."] Therefore they will not recall their own sins to memory.

❌ Objection 4 : Further, at the resurrection the damned will be to the good they once did as the blessed to the sins they once committed. Now seemingly the damned after rising again will have no knowledge of the good they once did, since this would alleviate their pain considerably. Neither therefore will the blessed have any knowledge of the sins they had committed.
