Who is the liar, if it is not the one who denies that Jesus is the Christ? This is the antichrist, who denies the Father and the Son.
Textus Receptus (TR) - 1 John 2:22 >Τίς ἐστιν ὁ ψεύστης, εἰ μὴ ὁ ἀρνούμενος ὅτι Ἰησοῦς οὐκ ἔστιν ὁ Χριστός; Οὗτός ἐστιν ὁ ἀντίχριστος, ὁ ἀρνούμενος τὸν πατέρα καὶ τὸν υἱόν.
