How that they told you there should be mockers in the last time, who should walk after their own ungodly lusts.

in the last time: That statement, and similar expressions that are to be found in Scripture do not enable us to know the exact length of time. For they are not intended to indicate a short length of time, but to signify the last state of the world, which is the last age of all, and it is not stated definitely how long this will last. Thus neither is fixed duration appointed to old age, which is the last age of man, since sometimes it is seen to last as long as or even longer than all the previous ages, as Augustine remarks (Qq. 83, qu. 58). Hence also the Apostle in 2 Thess. 2:2 disclaims the false signification which some had given to his words, by believing that the day of the Lord was already at hand. (St. Thomas Aquinas Sum Theo 3.88.3. r3)
