CLV(i)
8 Yet he who is doing sin is of the Adversary, for from the beginning is the Adversary sinning. For this was the Son of God manifested, that He should be annulling the acts of the Adversary."
9 Everyone who is begotten of God is not doing sin, for His seed is remaining in him, and he can not be sinning, for he is begotten of God."
10 In this are apparent the children of God and the children of the Adversary: everyone who is not doing righteousness is not of God, and who is not loving his brother."
