not to be quickly shaken in your mind, nor yet be troubled, either by spirit, or by word, or by letter as from us, saying that the day of Christ had come.
Nor by letter - Either the one which he had before written to them - the First Epistle to the Thessalonians - or one which had been forged in his name. “As from us.” That is, Paul, Silas, and Timothy, who are united in writing the two epistles 1 Thessalonians 1:1; 2 Thessalonians 1:1, and in whose names a letter would be forged, if one of this description were sent to them. It has been made a question, whether the apostle refers here to the former epistle which he had sent to them, or to a forged letter; and on this question critics have been about equally divided. The reasons for the former opinion may be seen in Paley’s Herin Paulinae, in loc. The question is not very important, and perhaps cannot be easily settled. There are two or three circumstances, however, which seem to make it probable that he refers to an epistle which had been forged, and which had been pretended to be received from him. (1.) one is found in the expression “as from us.” If he had referred to his own former letter, it seems to me that the allusion would have been more distinct, and that the particle “as” (ὡς hōs) would not have been used. This is such an expression as would have been employed if the reference were to such a forged letter.
