1 John 2:21-23

New Catholic Bible

²¹ I write to you
not because you do not know the truth
but because you do know it,
and because no lie can come from the truth.
²² Who is the liar
but the one who denies that Jesus is the Christ?
The antichrist is
anyone who denies both the Father and the Son.
²³ Whoever denies the Son
does not have the Father,
but whoever acknowledges the Son
has the Father also.
