Luke 22:70

‘And they all said, “Are you then the Son of God?” And he said to them, “You say that I am.” '

This claim that He would sit at the right hand of God in such a way could only mean one thing to them and that was that He was claiming to be more than just the Messiah. He was claiming a divine Messiahship. So they ‘all' questioned Him further. (This is not the High Priest dunning Him). Was He then claiming to be  the  Son of God? This does not just mean the Messiah. To claim to be the Messiah was not in itself blasphemy. It was the claim that He would be literally exalted and seated at God's right hand that was seen as the blasphemy. They rightly recognised within it a claim to some kind of divinity. Jesus reply was simple. ‘It is you who have said that I am.' It was an admission made in all humility. He would accept their verdict on what He had said, but wanted them to understand that He did not necessarily accept what they had said on their terms, for He had little regard for their understanding.
