If He can be known it will be by self-revelation on His part, not speculation on ours. We, therefore, look for Him where it is claimed that He has revealed Himself by miracle, by inspired teachers, by enjoined ritual. The traditions conflict, yet the longer and more sympathetically we study them the more we become aware of a common element in many of them: the theme of sacrifice, of mystical communion through the shed blood, of death and rebirth, of redemption, it is too clear to escape notice. We are fully entitled to use moral and intellectual criticism. What we are not, in my opinion, entitled to do is simply to abstract the ethical element and set that up as a religion on its own. Rather in that tradition which is at once more completely ethical and most transcends me your ethics…we may still most reasonably believe that we have the consummation of all religion, the fullest message from the wholly other, the living creator, who, if He is at all, must be the God not only of the philosophers, but of mystics and savages, not only of the head and heart, but also of the primitive emotions in the spiritual heights beyond all emotion. We may…attach ourselves to the Church, to the only concrete organization which has preserved down to this present time the core of all the messages, pagan and perhaps pre-pagan, that have ever come from beyond the world, and begin to practise the only religion which rests not upon some selection of certain supposedly ’higher’ elements in our nature, but on the shattering and rebuilding, the death and rebirth, of that nature in every part: neither Greek nor Jew nor barbarian, but a new creation.
