Whether the punishment of Christians is brought to an end by the mercy of God?

Objections

Objection 1 : It would seem that at least the punishment of Christians is brought to an end by the mercy of God. "For he that believeth and is baptized shall be saved" (Mk. 16:16). Now this applies to every Christian. Therefore all Christians will at length be saved.
Objection 2 : Further, it is written (Jn. 6:55): "He that eateth My body and drinketh My blood hath eternal life." Now this is the meat and drink whereof Christians partake in common. Therefore all Christians will be saved at length.
Objection 3 : Further, "If any man's work burn, he shall suffer loss: but he himself shall be saved, yet so as by fire" (1 Cor. 3:15), where it is a question of those who have the foundation of the Christian faith. Therefore all such persons will be saved in the end.
