1 John 2:10-11

2:10 The one who loves his fellow Christian ¹  resides in the light, and there is no cause for stumbling in him. ²  2:11 But the one who hates his fellow Christian ³  is in the darkness, walks in the darkness, and does not know where he is going, because the darkness has blinded his eyes. ⁴ 

[2:10]  ¹ tn See note on the term “fellow Christian” in 2:9.

[2:10]  ² tn The third person pronoun αὐτῷ (autw) could refer either (1) to the person who loves his brother or (2) to the light itself which has no cause for stumbling “in it.” The following verse (2:11) views darkness as operative within a person, and the analogy with Ps 119:165, which says that the person who loves God’s law does not stumble, expresses a similar concept in relation to an individual. This evidence suggests that the person is the referent here.

[2:11]  ³ sn The one who hates his fellow Christian. The author’s paradigm for the opponents portrays them as those who show hatred for fellow Christians (Grk “brothers,” but not referring to one’s physical siblings). This charge will be much more fully developed in chap. 3, where the author will compare the opponents to Cain (who is the model for one who hates a brother, since he ultimately murdered his own brother). In 1 John 3:17 the specific charge against the opponents will be failing to give material aid to a brother in need.

[2:11]  ⁴ sn 1 John 2:3-11. The section 2:3-11 contains three claims to intimate knowledge of God, each introduced by the phrase the one who says (participles in the Greek text) in 2:4, 6, and 9. As with the three claims beginning with “if” in the previous section (1:6, 8, 10), these indirectly reflect the claims of the opponents. Each claim is followed by the author’s evaluation and its implications.
