18 But others mocking said, They are full of new wine, and they spoke truly though in mockery. For in truth the wine was new, even the grace of the New Testament; but this new wine was from a spiritual Vine, which had oftentimes ere this borne fruit in Prophets, and had budded in the New Testament. For as in things sensible, the vine ever remains the same, but bears new fruits in its seasons, so also the self-same Spirit continuing what He is, as He had often wrought in Prophets, now manifested a new and marvellous work. For though His grace had come before to the Fathers also, yet here it came exuberantly; for formerly men only partook of the Holy Ghost, but now they were baptized completely.
