Although the issue of wine in the Lord’s supper is a contentious and complicated one, I believe we can cut through all the hot air and make a compelling case for wine, in just 3 lines:
- To the best of our ability, we should conduct the Lord’s supper in the manner instituted by Jesus.
- Jesus instituted the Lord’s supper with bread and grape wine.
- Therefore, to the best of our ability, we should conduct the Lord’s supper with bread and grape wine.
(2) is a matter of historical fact, so the only premise to push back on here is (1). But how? Certainly we can say there is some fuzziness in the extent of the referent for “do this in remembrance of me”. But fuzziness in defining the outer limits of the sacrament doesn’t affect clarity in defining its inner limits. In terms of the minimal constituents, obviously two of them are unleavened bread being broken, and grape wine being drunk.
Btw, notice the logical corollary of (3):
- To the best of our ability, we should not conduct the Lord’s supper without bread and grape wine.
