The only way the Greek language can express “eternal,” apart from textual considerations, is by using the noun form of aionios (aion) in the plural (“ages” [e.g., Luke 1:33; Hebrews 13:8]), or by using aion twice in the plural (“unto the ‘ages [aionas]’ of the ‘ages [aionon]’” [e.g., Revelation 1:6, 18; 4:9, 10; 5:13, 14; 7:12; 10:6; 11:15; 14:11; 15:7; 19:3; 20:10; 22:5]).
