1 John 2:7-9

New Revised Standard Version, Anglicised Catholic Edition

A New Commandment

⁷ Beloved, I am writing you no new commandment, but an old commandment that you have had from the beginning; the old commandment is the word that you have heard. ⁸ Yet I am writing you a new commandment that is true in him and in you, because^[a] the darkness is passing away and the true light is already shining. ⁹ Whoever says, ‘I am in the light’, while hating a brother or sister,^[b] is still in the darkness.
