1 Thessalonians 5:1

For when they shall say, `Peace, 'and `All things are safe, 'then sudden destruction shall come upon them." Again, in the second epistle he addresses them with even greater earnestness: "Now I beseech you, brethren, by the coming of our Lord Jesus Christ, and by our gathering together unto Him, that ye be not soon shaken in mind, nor be troubled, either by spirit, or by word," that is, the word of false prophets, "or by letter," that is, the letter of false apostles, "as if from us, as that the day of the Lord is at hand.

"But concerning the times and the seasons, brethren, ye have no need that aught be written unto you. For yourselves know perfectly that the day of the Lord so cometh as a thief in the night." Nothing, as it seems, is so curious, and so fondly prone to pry into things obscure and concealed, as the nature of men. And this is wont to happen to it, when the mind is unsettled and in an imperfect state. Why has he not said that no one knows? why has he not said, that it is not revealed, instead of saying, "Ye have no need that aught be written unto you"? Because in that case he would have grieved them more, but by speaking thus he comforted them. For by the expression, "Ye have no need," as if it were both superfluous, and inexpedient, he suffers them not to enquire. For tell me, what would be the advantage? Let us suppose that the end would be after twenty or thirty or a hundred years, what is this to us? Is not the end of his own life the consummation to every individual? Why art thou curious, and travailest about the general end? But the case is the same with us in this, as in other things. For this reason Christ did not tell it, because it was not expedient. Hear Paul saying, "For yourselves know perfectly that the day of the Lord so cometh as a thief in the night." Not the general day only, but that of every individual. For the one resembles the other, is also akin to it. For what the one does collectively, that the other does partially. For the period of consummation took its beginning from Adam, and then is the end of the consummation; since even now one would not err in calling it a consummation.

It is superfluous and useless to know "the times and the seasons" of the end (Acts 1:7). Even to the apostles the Lord did not reveal this, when they, having approached, asked Him. But Paul, from the "unspeakable words" (2 Cor. 12:4), could perhaps have …

In what he had written before, Paul corrected them in matters which needed to be improved upon, and now he begins to instruct them concerning the future. He first gives them a warning and then provides a prayer with the words, may the God of …

The thing is certain that Christ will come, and there is a certain time appointed for his coming; but there was no need that the apostle should write about this, and therefore he had no revelation given him; nor should they or we enquire into this secret, which the Father has reserved in his own power.
