This is the reason that I said (I think it was in the second hour of these lectures) something about which l have often been asked in the meantime, and which I want to repeat now, in order to say what I believe IS the criterion of the REALLY ultimate.^e We cannot have the really ultimate as something which we can grasp---then it wouldn't be ultimate at all. Ultimacy^f includes transcendence beyond anything relative, and our language, and everything we would say about the ultimate, IS relative. Therefore I said: the ONLY real ultimate is that finite which sacrifices itself AS finite.^g I referred this to the Messiah who, against all expectations, instead of bringing a new period of history, was crucified by the OLD period of history. Then I got from many of you the question, "Now there are so MANY martyrs; self-sacrifice^h canNOT be a criterion, because in every very idolatrousⁱ or quasi-religious movement, there are people who sacrifice themselves." Now this was a misunderstanding, for which I am responsible, and therefore I am glad that
