Chapter 18 — Part II: The Sacraments — The Holy Eucharist
Section 37. That in the institution of this Sacrament our Lord and Saviour made use of wine has beep at all times the doctrine of the Catholic Church, for He Himself said: I will not drink from henceforth of this fruit of the vine until that day. On this passage Chrysostom observes: He says, "Of the fruit of the vine," which certainly produced wine not water; as if he had it in view, even at so early a period, to uproot the heresy which asserted that in these mysteries water alone is to be used.
