Whether, by Penance, man is restored to his former dignity?

Objections

Objection 1 : It would seem that man is not restored by Penance to his former dignity: because a gloss on Amos 5:2, "The virgin of Israel is cast down," observes: "It is not said that she cannot rise up, but that the virgin of Israel shall not rise; because the sheep that has once strayed, although the shepherd bring it back on his shoulder, has not the same glory as if it had never strayed." Therefore man does not, through Penance, recover his former dignity.
Objection 2 : Further, Jerome says: "Whoever fail to preserve the dignity of the sacred order, must be content with saving their souls; for it is a difficult thing to return to their former degree." Again, Pope Innocent I says (Ep. vi ad Agapit.) that "the canons framed at the council of Nicaea exclude penitents from even the lowest orders of clerics." Therefore man does not, through Penance, recover his former dignity.
Objection 3 : Further, before sinning a man can advance to a higher sacred order. But this is not permitted to a penitent after his sin, for it is written (Ezech. 44:10,13): "The Levites that went away . . . from Me . . . shall never [Vulg.: 'not'] come near to Me, to do the office of priest": and as laid down in the Decretals (Dist. 1, ch. 52), and taken from the council of Lerida: "If those who serve at the Holy Altar fall suddenly into some deplorable weakness of the flesh, and by God's mercy do proper penance, let them return to their duties, yet so as not to receive further promotion." Therefore Penance does not restore man to his former dignity.
