Definition of "inassimilable"

I suggest that the allosemitism endemic to western Civilization is to a decisive extent the legacy of Christendom. The Christian Church's struggle with the inassimilable, yet indispensable modality of the Jews bequeathed to later ages two factors crucial to the emergence and self-perpetuation of allosemitism.
