To this rule of knowing no one after the flesh Paul can admit no exception. Not even Christ is excepted. "Even though we have known Christ after the flesh, yet now we know Him so no more." This is a difficult saying, and has been very variously interpreted. The English reader inevitably supposes that Paul _had_ known Christ "after the flesh," but had outgrown that kind of knowledge; and that he is intimating these two facts. But it is quite possible to take the words[48] as purely hypothetical: "Supposing us to have known even Christ after the flesh--a case which in point of fact was never ours--yet now we know Him so no more." Grammar does not favour this last rendering, though it does not preclude it; and however the matter may be settled, the bare supposition, as much as the fact, requires us to give a definite meaning to the words about knowing Christ after the flesh, and ceasing so to know Him.
Some have inferred from them that when Paul became a Christian, and for some time after, his conception of Christ had resembled that of the persons whom he is here controverting: his Christ had been to all intents and purposes a Jewish Messiah, and he had only been able by degrees to overcome, though he had at last overcome, the narrowness and nationalism of his early years as a disciple. To know Christ after the flesh would be to know Him in the character of a deliverer of the Jews: His Jewish descent, His circumcision, His observance of the Temple worship, His limitation of His ministry to the Holy Land, would be matters of great significance; and Jewish descent might naturally be supposed to establish a prerogative in relation to the Messiah for Jews as opposed to Gentiles. Probably there were Christians whose original conception of the Saviour was of this kind, and it is a fair enough description to say that this amounts only to a knowing of Christ after the flesh; but Paul can hardly have been one of them. His Christian knowledge of Christ dates from his vision of the Risen Lord on the way to Damascus, and in that appearance there was no room for anything that could be called "flesh." It was an appearance of the Lord of Glory. It determined all Paul's thoughts thenceforth. Nothing is more remarkable in his Epistles than the strong sense that what he calls his Gospel is one, unchanged, and unchangeable. It is not Yes and No. Neither man nor angel may modify it by preaching another Jesus than he preaches. He is quite unconscious of any such transformation of his Christology as is indicated above; and in the absence of any trace elsewhere of a change so important, it is impossible to read it into the verse before us.
