Augustine of Hippo, on Luke 5:33

“And they said to him: Why do the disciples of John fast often, and make prayers, and the disciples of the Pharisees in like manner; but thine eat and drink?”

“(ubi sup.) Or else, The gift of the Holy Spirit being received, there is a kind of fast, which is of joy, which they who are already renewed to a spiritual life most seasonably celebrate. Before they receive this gift, He says they are as old garments, to which a new piece of cloth is most unsuitably sewed on, i. e. any part of the doctrine which relates to the soberness of the new life; for if this takes place, the very doctrine itself also is in a measure divided, for it teaches a general fast not from pleasant food only, but from all delight in temporal pleasures, the part of which that appertains to food He said ought not to be given to men still devoted to their old habits, for therein seems to be a rent, and it agreeth not with the old. He says also, that they are like to old skins, as it follows, And no one putteth wine into old skins.”
