1 John 2:6-8 New Revised Standard Version Catholic Edition (NRSVCE)
6 whoever says, “I abide in him,” ought to walk just as he walked.
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.
