1 John 2:21-23

Revised Standard Version Catholic Edition

²¹ I write to you, not because you do not know the truth, but because you know it, and know that no lie is of the truth. ²² Who is the liar but he who denies that Jesus is the Christ? This is the antichrist, he who denies the Father and the Son. ²³ No one who denies the Son has the Father. He who confesses the Son has the Father also.
