This correspondence of language and imagery suggests that Paul viewed the anticipated resurrection, transformation, and assumption of those who are Christ's to occur "at the last trumpet of God" (1 Thess 4:16; 1 Cor 15:52) upon Christ's descent from heaven (Phil 3:20; 1 Thess 4:16). Further, it appears that Paul viewed this transformation and assumption as the actual means by which Christ will rescue or save believers from the coming wrath (1 Thess 1:10; 5:9). In the Old Testament, the sounding of the trumpet is always pictured as preceding the period of judgment known as the Day of the Lord (Joel 2:1; cf. Jer 4:5, 19, 21) - Dr. Michael Svigel, The Fathers on the Future, p. 203
