7. In Isaiah also the Holy Spirit testifies this same thing concerning the Lord’s passion, saying, “Wherefore are Thy garments red, and Thy apparel as from the treading of the wine-press full and well trodden?” Can water make garments red? or is it water in the wine-press which is trodden by the feet, or pressed out by the press? Assuredly, therefore, mention is made of wine, that the Lord’s blood may be understood, and that which was afterwards manifested in the cup of the Lord might be foretold by the prophets who announced it. The treading also, and pressure of the wine-press, is repeatedly dwelt on; because just as the drinking of wine cannot be attained to unless the bunch of grapes be first trodden and pressed, so neither could we drink the blood of Christ unless Christ had first been trampled upon and pressed, and had first drunk the cup of which He should also give believers to drink.
