Order (tagmati). Old military term from tassw, to arrange, here only in N.T. Each in his own division, troop, rank. At his coming (en th parousiai). The word parousia was the technical word "for the arrival or visit of the king or emperor" and can be traced from the Ptolemaic period into the second century A.D. (Deissmann, Light from the Ancient East, p. 368). "Advent-coins were struck after a parousia of the emperor." Paul is only discussing "those that are Christ's" ( Romans 3:23 ; Galatians 5:24 ) and so says nothing about judgment (cf. 1 Thessalonians 2:19 ; 1 Thessalonians 3:13 ; 1 Thessalonians 4:15 ; 1 Thessalonians 5:23 ).
