"Christianity, by those doctrinal aspects that we have just emphasized as well as by others, brought something absolutely new into the world. Its concept of salvation is not merely novel in comparison with that of those religions in existence at the time of its birth. It is a unique phenomenon in the religious history of mankind.For what do we witness outside Christianity whenever a religious movement rises above the domain of sense and effectively transcends the limit of nationality? In every case, though appearances may differ considerably, the basis is the same—an individualist doctrine of escape. It was this that inspired ancient mysticism, whether it sought to escape the vicissitudes of the sub-lunary world or to pass over the outer circle of the cosmos and to penetrate into the realm of intelligible Essences or even beyond."
