Third Berlin Lecture

I myself must confess: the question of why Judas' betrayal was necessary, why it is seriously necessary that someone who could know from among the disciples, through the Judas kiss as if pointing to them with his fingers: “This is the one!”, that actually always seemed a strange message, until I knew that it was really impossible to know which of them it was, because he could speak through anyone; so that even if he was among them in the flesh, you could not recognize it by the body. For each one could be mistaken for him, depending on whether he spoke through one or the other. And each one spoke! It was only when one who knew, when the Christ Jesus was really in the body among them, told the Jews: This is he! — only then could he be seized.
