By its very nature, the Christian state is incapable of emancipating the Jew; but, adds Bauer, by his very nature the Jew cannot be emancipated. So long as the state is Christian and the Jew is Jewish, the one is as incapable of granting emancipation as the other is of receiving it.
The Christian state can behave towards the Jew only in the way characteristic of the Christian state – that is, by granting privileges, by permitting the separation of the Jew from the other subjects, but making him feel the pressure of all the other separate spheres of society, and feel it all the more intensely because he is in religious opposition to the dominant religion. But the Jew, too, can behave towards the state only in a Jewish way – that is, by treating it as something alien to him, by counterposing his imaginary nationality to the real nationality, by counterposing his illusory law to the real law, by deeming himself justified in separating himself from mankind, by abstaining on principle from taking part in the historical movement, by putting his trust in a future which has nothing in common with the future of mankind in general, and by seeing himself as a member of the Jewish people, and the Jewish people as the chosen people.

The most rigid form of the opposition between the Jew and the Christian is the religious opposition. How is an opposition resolved? By making it impossible. How is religious opposition made impossible? By abolishing religion. As soon as Jew and Christian recognize that their respective religions are no more than different stages in the development of the human mind, different snake skins cast off by history, and that man is the snake who sloughed them, the relation of Jew and Christian is no longer religious but is only a critical, scientific, and human relation. Science, then, constitutes their unity. But, contradictions in science are resolved by science itself.
From Karl Marx – On the Jewish Question
