It gets even better if you proceed and read Aphorism 8 in full knowledge of all the context of what Nietzsche thinks about Christianity (seeing it as a religion of weakness, slave morality and nihilism) after reading The Antichrist.
>But you understand this not? You have no eyes for a force which has taken two thousand years to achieve victory?—There is nothing wonderful in this: all lengthy processes are hard to see and to realise. But this is what took place: from the trunk of that tree of revenge and hate, Jewish hate,—that most profound and sublime hate, which creates ideals and changes old values to new creations, the like of which has never been on earth,—there grew a phenomenon which was equally incomparable, a new love, the most profound and sublime of all kinds of love;—and from what other trunk could it have grown? But beware of supposing that this love has soared on its upward growth, as in any way a real negation of that thirst for revenge, as an antithesis to the Jewish hate! No, the contrary is the truth! This love grew out of that hate, as its crown, as its triumphant crown, circling wider and wider amid the clarity and fulness of the sun, and pursuing in the very kingdom of light and height its goal of hatred, its victory, its spoil, its strategy,[Pg 32] with the same intensity with which the roots of that tree of hate sank into everything which was deep and evil with increasing stability and increasing desire. This Jesus of Nazareth, the incarnate gospel of love, this "Redeemer" bringing salvation and victory to the poor, the sick, the sinful—was he not really temptation in its most sinister and irresistible form, temptation to take the tortuous path to those very Jewish values and those very Jewish ideals? Has not Israel really obtained the final goal of its sublime revenge, by the tortuous paths of this "Redeemer," for all that he might pose as Israel's adversary and Israel's destroyer? Is it not due to the black magic of a really great policy of revenge, of a far-seeing, burrowing revenge, both acting and calculating with slowness, that Israel himself must repudiate before all the world the actual instrument of his own revenge and nail it to the cross, so that all the world—that is, all the enemies of Israel—could nibble without suspicion at this very bait? Could, moreover, any human mind with all its elaborate ingenuity invent a bait that was more truly dangerous? Anything that was even equivalent in the power of its seductive, intoxicating, defiling, and corrupting influence to that symbol of the holy cross, to that awful paradox of a "god on the cross," to that mystery of the unthinkable, supreme, and utter horror of the self-crucifixion of a god for the salvation of man? It is at least certain that sub hoc signo Israel, with its revenge and transvaluation of all values, has up to the present always triumphed again over[Pg 33] all other ideals, over all more aristocratic ideals.
