Lk 9:18-22
Now it happened that he was praying alone, and his disciples came to him and he put this question to them, ‘Who do the crowds say I am?’ And they answered, ‘Some say John the Baptist; others Elijah; others again one of the ancient prophets come back to life.’ ‘But you,’ he said to them, ‘who do you say I am?’ It was Peter who spoke up. ‘The Christ of God,’ he said.
