Bede the Venerable
Catena Aurea · Lukasevangelium 9
And it came to pass, as he was alone praying, his disciples were with him: and he asked them, saying, Whom say the people that I am? They answering said, John the Baptist; but some say, Elias; and others say, that one of the old prophets is risen again. He said unto them, But whom say ye that I am? Peter answering said, The Christ of God. And he straitly charged them, and commanded them to tell no man that thing; Saying, The Son of man must suffer many things, and be rejected of the elders and Chief Priests and Scribes, and be slain, and be raised the third day.
Rightly does our Lord, when about to enquire into the faith of the disciples, first inquire into the opinion of the multitudes, lest their confession should appear not to be determined by their knowledge, but to be formed by the opinion of the generality, and they should be considered not to believe from experience, but like Herod to be perplexed by different reports which they heard.
