John 4:22

ὑμεῖς προσκυνεῖτε ὃ οὐκ οἴδατε. The distinction between Jewish and Samaritan worship lies not in the difference of place, but of the object of worship. The neuter refers abstractly to the object of worship. “You do not know the object of your worship;” suggested by the τῷ πατρί of the preceding clause. Cf. Acts 17:23. ἡμεῖς προσκυνοῦμεν ὃ οἴδαμεν. The Jews worshipped a God who had made Himself known to them in their history by His gracious and saving dealings with them. That it is this knowledge which is meant appears in the following clause: ὅτι ἡ σωτηρία ἐκ τῶν Ἰουδαίων ἐστίν, that is to say, God has manifested Himself as Saviour to the Jews, and through them to all. “A powerful repudiation of the theory which makes the author of this Gospel a Gentile of the second century with a Gnostic antipathy to Judaism and Jews,” Reynolds.
