Whether the time of the future judgment is unknown?

Objections

Objection 1 : It would seem that the time of the future judgment is not unknown. For just as the holy Fathers looked forward to the first coming, so do we look forward to the second. But the holy Fathers knew the time of the first coming, as proved by the number of weeks mentioned in Daniel 9: wherefore the Jews are reproached for not knowing the time of Christ's coming (Lk. 12:56): "You hypocrites, you know how to discern the face of the heaven and of the earth, but how is it that you do not discern this time?" Therefore it would seem that the time of the second coming when God will come to judgment should also be certified to us.
Objection 2 : Further, we arrive by means of signs at the knowledge of the things signified. Now many signs of the coming judgment are declared to us in Scripture (Mt. 24, Mk. 13, Lk. 21). Therefore we can arrive at the knowledge of that time.
Objection 3 : Further, the Apostle says (1 Cor. 10:11): "It is on us [*'These things . . . are written for our correction, upon whom the ends of the world are come'] that the ends of the world are come," and (1 Jn. 2:18): "Little children, it is the last hour," etc. Since then it is a long time since these things were said, it would seem that now at least we can know that the last judgment is nigh.
Objection 4 : Further, there is no need for the time of the judgment to be hidden, except that each one may be careful to prepare himself for judgment, being in ignorance of the appointed time. Yet the same care would still be necessary even were the time known for certain, because each one is uncertain about the time of his death, of which Augustine says (Ep. ad Hesych. cxcix) that "as each one's last day finds him, so will the world's last day find him." Therefore there is no necessity for the time of the judgment to be uncertain.
