John Chrysostom — as excerpted in the Catena Aurea on John 4:19-24

“(Hom. xxxiii. 1) There was no necessity for Christ to shew why the fathers worshipped in the mountain, and the Jews in Jerusalem. He therefore was silent on that question; but nevertheless asserted the religious superiority of the Jews on another ground, the ground not of place, but, of knowledge; Ye worship ye know not what, we know what we worship; for salvation if of the Jews.”
