Catena Aurea · Lukasevangelium 7
And all the people that heard him, and the Publicans, justified God, being baptized with the baptism of John. But the Pharisees and Lawyers rejected the counsel of God against themselves, being not baptized of him. And the Lord said, Whereunto then shall I liken the men of this generation? and to what are they like? They are like unto children sitting in the marketplace, and calling one to another, and saying, We have piped unto you, and ye have not danced; we have mourned to you, and ye have not wept. For John the Baptist came neither eating bread nor drinking wine; and ye say, He hath a devil. The Son of man is come eating and drinking; and ye say, Behold a gluttonous man, and a winebibber, a friend of Publicans and sinners! But wisdom is justified of all her children.
(Hom. 6. in Eccl.) But singing and lamentation are nothing else but the breaking forth, the one indeed of joy, the other of sorrow. Now at the sound of a tune played upon a musical instrument, man by the concordant beating of his feet, and motion of his body, pourtrays his inward feelings. Hence he says, We have sung, and ye have not danced; we have mourned to you, and ye have not wept.
