[1:8] 1 tn Grk “say we do not have sin.” The use of ἔχω + ἁμαρτία (ecw + Jamartia) is an expression limited to John and 1 John in the NT. On the analogy with other constructions where ἔχω governs an abstract noun (e.g., 1 John 1:3, 6, 7; 2:28; 3:3, 15, 21; 4:16, 17; 5:12-13), it indicates that a state is involved, which in the case of ἁμαρτία would refer to a state of sin. The four times the expression ἔχω + ἁμαρτία occurs in the Gospel of John (9:41; 15:22, 24; 19:11) all refer to situations where a wrong action has been committed or a wrong attitude has already existed, resulting in a state of sin, and then something else happens which further emphasizes the evil of that action or attitude. Here in 1 John 1:8 the sense is the same. The author is addressing people who have sinned (resulting in a state of sin), warning them that they cannot claim to be free from the guilt of that sin. The context of 1 John does not imply libertinism (where sins are flaunted as a way of demonstrating one’s “liberty”) on the part of the opponents, since the author makes no explicit charges of immoral behavior against his opponents. The worst the author explicitly says is that they have failed to love the brethren (1 John 3:17). It seems more likely that the opponents were saying that things a believer did after conversion were not significant enough to be “sins” that could challenge one’s intimate relationship with God (a relationship the author denies that the opponents have to begin with).
[3:5] 2 tn Grk “that one.” The context makes it clear that this is a reference to Jesus, because the reader is told “he was revealed in order that he might take away sins.” The connection with Jesus as the Lamb of God who takes away the sin of the world in John 1:29 provides additional confirmation that the previous use of ἐκεῖνος (ekeinos) in 3:3b should also be understood as a reference to Jesus, as 2:6 was.
[3:5] 3 tn The ἵνα (Jina) clause gives the purpose of Jesus’ self-revelation as he manifested himself to the disciples and to the world during his earthly life and ministry: It was “to take away sins.”
