Truly Jesus Himself shall extinguish by His presence that last persecution which is to be made by Antichrist. For so it is written, that "He shall slay him with the breath of His mouth, and empty him with the brightness of His presence."[613] It is customary to ask, When shall that be? But this is quite unreasonable. For had it been profitable for us to know this, by whom could it better have been told than by God Himself, the Master, when the disciples questioned Him? For they were not silent when with Him, but inquired of Him, saying, "Lord, wilt Thou at this time present the kingdom to Israel, or when?"[614] But He said, "It is not for you to know the times, which the Father hath put in His own power." When they got that answer, they had not at all questioned Him about the hour, or day, or year, but about the time. In vain, then, do we attempt to compute definitely the years that may remain to this world, when we may hear from the mouth of the Truth that it is not for us to know this. Yet some have said that four hundred, some five hundred, others a thousand years, may be completed from the ascension of the Lord up to His final coming. But to point out how each of them supports his own opinion would take too long, and is not necessary; for indeed they use human conjectures, and bring forward nothing certain from the authority of the canonical Scriptures. But on this subject He puts aside the figures of the calculators, and orders silence, who says, "It is not for you to know the times, which the Father hath put in His own power."
