Origen
Catena Aurea · Lukasevangelium 3
And many other things in his exhortation preached he unto the people. But Herod the tetrarch, being reproved by him for Herodias his brother Philip’s wife, and for all the evils which Herod had done, Added yet this above all, that he shut up John in prison.
And as in the Gospel according to St. John it is related of Christ that He spoke many other things, so also in this place we must understand Luke to say the same of John the Baptist, since certain things are announced by John too great to be entrusted to writing. But we marvel at John, because among them that are born of women there was not a greater than he, for by his good deeds he had been exalted to so high a fame for virtue, that by many he was supposed to be Christ. But what is much more marvellous he feared not Herod, nor dreaded death, as it follows, But Herod the tetrarch being reproved by him.
