I answer that, This sacrament can only be performed with wine from the grape. First of all on account of Christ’s institution, since He instituted this sacrament in wine from the grape, as is evident from His own words, in instituting this sacrament (Matthew 26:29): “I will not drink from henceforth of this fruit of the vine.” Secondly, because, as stated above (3), that is adopted as the matter of the sacraments which is properly and universally considered as such. Now that is properly called wine, which is drawn from the grape, whereas other liquors are called wine from resemblance to the wine of the grape. Thirdly, because the wine from the grape is more in keeping with the effect of this sacrament, which is spiritual; because it is written (Psalm 103:15): "That wine may cheer the heart of man."
