Remigius of Auxerre
Catena Aurea · Matthäusevangelium 14
But when Herod’s birthday was kept, the daughter of Herodias danced before them, and pleased Herod. Whereupon he promised with an oath to give her whatsoever she would ask. And she, being before instructed of her mother, said, Give me here John Baptist’s head in a charger. And the king was sorry: nevertheless for the oath’s sake, and them which sat with him at meat, he commanded it to be given her. And he sent, and beheaded John in the prison. And his head was brought in a charger, and given to the damsel: and she brought it to her mother. And his disciples came, and took up the body, and buried it, and went and told Jesus.
Otherwise; The beheading of John marks the increase of that fame which Christ has among the people, as the exaltation of the Lord upon the cross marks the progress of the faith; whence John had said, He must increase, but I must decrease. (John 3:30.)
