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

“(Hom. xxxiii. 1) The Jewish worship then was far higher than the Samaritan; but even it shall be abolished; The hour cometh, and now is, when, the true worshippers shall worship the Father in spirit and in truth. He says, and now is, to shew that this was not a prediction, like those of the ancient Prophets, to be fulfilled in the course of ages. The event, He says, is now at hand, it is approaching your very doors. The words, true worshippers, are by way of distinction: for there are false worshippers who pray for temporal and frail benefits, or whose actions are ever contradicting their prayers.”
