Lecture XI
And now Christ Jesus asks: What is it that must come to men through my impulse?—It is the life-giving, Spirit-principle from above! Thus a distinction must be made between the Son of Man who has grown upwards from below the Son of God, the Son of the living God, who comes down from above. But the difficulty of this question for the disciples will be apparent to you when you realise that they were the very first to receive what the simplest of men since the time of Christ Jesus have received through the Gospels. It was only the living forces of Christ Jesus that enabled the disciples to assimilate all this teaching. The faculties they had already developed were not capable of answering the question: Of whom am I myself the representative? The Gospel then records that one of the disciples, Peter by name, gave the answer: ‘Thou art the Christ, the Son of the living God!’ At the moment of its utterance, this was an answer that did not issue from Peter's normal spiritual faculties.
