1 John 3:11 New English Translation

¹¹For^[a] this is the gospel^[b] message^[c] that you have heard from the beginning: that we should love one another,^[d]

1 John 3:11 tn It could be argued (1) that the ὅτι (hoti) at the beginning of 3:11 is grammatically subordinate to the preceding statement at the end of 3:10. As BDF §456.1 points out, however, “Subordination with ὅτι and διότι is often very loose…and must be translated ‘for.’” Thus (2) ὅτι assumes an inferential sense, standing at the beginning of a new sentence and drawing an inference based upon all that has preceded. This is confirmed by the structural parallel between the present verse and 1:5.
1 John 3:11 tn The word “gospel” is not in the Greek text but is supplied to clarify the meaning. See the notes on the words “gospel” and “message” in 1 John 1:5.
1 John 3:11 tn See the note on the word “message” in 1 John 1:5, where this same phrase occurs.
1 John 3:11 sn For this is the gospel message…that we should love one another. The structure of this verse is parallel to 1:5, indicating the beginning of a second major section of the letter.
