Another Ignored Truth About Christianity - Mark Directed His Gospel at those ALREADY ESTABLISHED AS JEWISH PROSELYTES Rather Than 'The Gentiles'

You have to read the following with some sensitivity. The Marcionites (Aram = 'those of Mark') knew that the gospel was directed against those WHO HAD ALREADY COME OVER to Judaism. It was the Catholici who thought that the apostles directed their message at the Gentiles.

Refuted however on the [apostolic] vocation of the gentiles, you now turn back to proselytes. You ask who they are from among the gentiles, that are passing over to the Creator, when those specifically mentioned by the prophet are proselytes, of a different condition, separate, by
themselves: Behold, Isaiah says, proselytes by me shall come near unto thee,a showing that even proselytes were to come to God through Christ. Also the gentiles, which we are, likewise had their own mention, as people that were hoping in Christ: And in his name, he says, shall the gentiles hope.b Proselytes however, whom you interpolate into the prophecy concerning the gentiles, do not as a rule hope in Christ's name, but in Moses' law, from which their instruction comes: whereas the promotion of the gentiles has come about in these last days. In those very words Isaiah says, And it shall come to pass in the last days that the mountain of the Lord shall be manifest, namely, the majesty of God, and the temple of God above the top of the mountains, meaning Christ, the catholic temple of God, in whom God is worshipped, established above all the eminences of virtues and powers: and all the nations shall come to it, and many shall go and say, Come ye, let us go up into the mountain of the Lord, and into the house of the God of Jacob, and he will announce to us his way, and we will walk in it: for out of Sion shall go forth a law, and the word of the Lord out of Jerusalem. This way must be the gospel of the new law, and of the new word in Christ, no longer in Moses. And he will judge among the nations, in respect of their error: and he shall confute a large people, in the first instance that of the Jews and their proselytes. [Tertullian Against Marcion iii.21]

Who was right? Clearly the Marcionites. How could ignorant Gentiles understand the sophisticated underpinning of the gospel? How could these people understand the writings of the Apostle? Christianity can only make sense to those who are already grounded in the Old. Only those who thought that making sense of Christianity WASN'T IMPORTANT, that it didn't have to be approached rationally could have thought otherwise.
