Lev (Léon) Shestov, a Russian Jew who later became a French Jew and even converted to Catholicism, defined God not by His power to create the laws of universe, but His ability to break them at will - the capacity for miracles. God could cancel the past! For instance, God could decide retrospectively, that Socrates was never poisoned... Assimilation demanded a miracle: that you stop having been somebody else before... But only God can do it.
