A.T. Robertson Commentary 1 Corinthians 15:23

"But each in his own order: Christ the firstfruits; then they that are Christ`s, at his coming." — 1 Corinthians 15:23 (ASV)

Order (ταγματ). Old military term from τασσω, to arrange, here only in N.T. Each in his own division, troop, rank.

At his coming (εν τη παρουσια). The word παρουσια 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" (3:23; Galatians 5:24) and so says nothing about judgment (cf. 1 Thessalonians 2:19; 3:13; 4:15; 5:23).
