⁵ tn The key to understanding the first major section of 1 John, 1:5-3:10, is found in the statement in v. 5: “God is light and in him there is no darkness at all.” The idea of “proclamation” – the apostolic proclamation of eyewitness testimony which the prologue introduces (1:2, 3) – is picked up in 1:5 by the use of the noun ἀγγελία (angelia) and the verb ἀναγγέλλομεν (anangellomen), cognate to the verb in 1:3. The content of this proclamation is given by the ὅτι (Joti) clause in 1:5 as the assertion that God is light, so this statement should be understood as the author’s formulation of the apostolic eyewitness testimony introduced in the prologue. (This corresponds to the apostolic preaching elsewhere referred to as κήρυγμα [khrugma], although the term the Apostle John uses here is ἀγγελία.)
