1 John 2:22-24

New Catholic Bible

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.
²⁴ Let what you heard from the beginning
remain in you.
If what you heard from the beginning
remains in you,
then you will remain in the Son
    and in the Father
