Thessalonians, Epistle to the, epistles of St. Paul to the Church at Thessalonica; of which there are two; the first written from Corinth about A.D. 53 to exhort them to beware of lapsing, and comforting them with the hope of the return of the Lord to judgment; the second, within a few months after the first, to correct a false impression produced by it in connection with the Lord's coming; they must not, he argued, neglect their ordinary avocations, as though the day of the Lord was close at hand; that day would not come till the powers of evil had wrought their worst, and the cup of their iniquity was full; this is the first purely dogmatic epistle of St. Paul.
