  Three months later, having returned to Berlin in October of 1913, Rosenzweig reversed his decision, this as a result of a new conception of Judaism which would remain central to his thought for the rest of his life. Through its mission of neighborly love, Rosenzweig continued to maintain, Christianity carries out the redemptive realization of unity in the world. But Judaism also has a vital role to play in the world’s redemption. The Jewish people lives in large part closed off from the rest of the world; but in its insular communal life, Rosenzweig now claims, it anticipates the ultimate redemption, and thereby represents to the rest of the world the goal they must ever pursue. Having arrived at a manner of grasping the reconciliation of the self and the world in history that was common to Christianity and Judaism, Rosenzweig no longer saw himself compelled to convert, and instead committed himself to a return to the Judaism that was his by birth.
