² tn BDAG 50 s.v. ἁμαρτία 1 defines this term as “a departure fr. either human or divine standards of uprightness” (see 1 John 5:17 where ἁμαρτία [Jamartia] and ἀδικία [adikia] are related). This word occurs 17 times in 1 John, of which 11 are singular and 6 are plural.

¹ tn There is a play on words in Greek, but this is difficult to express adequately in English. The verb ἀδικέω (adikew) as a passive means “to suffer harm,” or “to suffer an injustice.” The noun ἀδικία (adikia) means “unrighteousness.” Since the Greek verb has a wider field of meaning than the English, to translate it as suffer an injustice is unwarranted, for it implicitly attributes evil to God. As R. Bauckham notes, “in English it is impossible to translate ἀδικούμενοι as a morally neutral term and ἀδικίας with a morally pejorative term, while retaining the play on words” (Jude, 2 Peter [WBC], 265).

¹ tn The meaning of ἀδικία (adikia) here is “unrighteousness” (BDAG 20 s.v. 2). It refers to the opposite of that which is δίκαιος (dikaios, “right, just, righteous”) which is used by the author to describe both God and Jesus Christ (1 John 1:9; 2:2, 29). Here, having implied that sins committed by believers (sins “not to death”) may be prayed for and forgiven, the author does not want to leave the impression that such sin is insignificant, because this could be viewed as a concession to the views of the opponents (who as moral indifferentists have downplayed the significance of sin in the Christian’s life).
