John 4:21

Everywhere, beloved, we have need of faith, faith the mother of blessings, the medicine of salvation; and without this it is impossible to possess any one of the great doctrines. Without this, men are like to those who attempt to cross the open sea without a ship, who for a little way hold out by swimming, using both hands and feet, but when they have advanced farther, are quickly swamped by the waves: in like manner they who use their own reasonings, before they have learnt anything, suffer shipwreck; as also Paul saith, "Who concerning faith have made shipwreck." (1 Tim. i. 19.) That this be not our case, let us hold fast the sacred anchor by which Christ bringeth over the Samaritan woman now.

An exceedingly great doctrine He revealed to her, and one which He did not mention either to Nicodemus or Nathanael. She was eager to prove her own privileges more honorable than those of the Jews; and this she subtly argued from the Fathers, but Christ met not this question. For it was for the time distracting to speak on the matter, and to show why the Fathers worshiped in the mountain, and why the Jews at Jerusalem. Wherefore on this point He was silent, and having taken away from both places priority in dignity, rouses her soul by showing that neither Jews nor Samaritans possessed anything great in comparison with that which was to be given; and then He introduceth the difference. Yet even thus He declared that the Jews were more honorable, not preferring place to place, but giving them the precedence because of their intention. As though He had said, "About the 'place' of worship ye have no need henceforth to dispute, but in the 'manner' the Jews have an advantage over you Samaritans, for 'ye,' He saith, 'worship ye know not what; we know what we worship.'"

How then did the Samaritans "know not" what they worshiped? Because they thought that God was local and partial; so at least they served Him, and so they sent to the Persians, and reported that "the God of this place is wroth with us" (2 Kings xxvi.), in this respect forming no higher opinion of Him than of their idols. Wherefore they continued to serve both Him and devils, joining things which ought not to be joined. The Jews, on the contrary, were free from this supposition, at least the greater part of them, and knew that He was God of the world. Therefore He saith, "Ye worship ye know not what; we know what we worship." Do not wonder that He numbereth Himself among Jews, for He speaketh to the woman's opinion of Him as though He were a Jewish Prophet, and therefore He putteth, "we worship." For that He is of the objects of worship is clear to every one, because to worship belongs to the creature, but to be worshiped to the Lord of the creature. But for a time He speaketh as a Jew; and the expression "we" in this place meaneth "we Jews." Having then exalted what was Jewish, He next maketh Himself credible, and persuadeth the woman to give the greater heed to His words, by rendering His discourse above suspicion, and showing that He doth not exalt what belongs to them by reason of relationship to those of His own tribe. For it is clear, that one who had made these declarations concerning the place on which the Jews most prided themselves, and thought that they were superior to all, and who had taken away their high claims, would not after this speak to get favor of any, but with truth and prophetic power. When therefore He had for a while removed her from such reasonings, saying, "Woman, believe Me," and what follows, then He addeth...

"For salvation is of the Jews." What He saith is of this kind: neither, that blessings to the world came from them, (for to know God and condemn idols had its beginning, from them, and with you the very act of worship, although ye do it not rightly, yet received its origin from them,) or else, He speaketh of His own Coming. Or rather, one would not be wrong in calling both these things "salvation" which He said was "of the Jews"; which Paul implied when he said, "Of whom is Christ according to the flesh, who is God over all." (Rom. ix. 5.) Seest thou how He commendeth the old Covenant, and showeth that it is the root of blessings, and that He is throughout not opposed to the Law, since He maketh the groundwork of all good things to come from the Jews?

(Tr. xv. c. 24) Believe Me, our Lord says with fitness, as the husband is now present. For now there is one in thee that believes, thou hast begun to be present in the understanding; but if ye will not believe, surely ye shall not be established. (Isa. 7:9)
