What if there is no wine?

Here is what John Broadus thought:

"Well, suppose you want to observe the Lord's Supper and there is no wine to be had - a thing much more likely to happen than that there should be no water, and which I once knew to happen in a country neighborhood - why not take some other beverage, and let that represent to us the same thing as wine? We should all unite in raising two objections. First, our Lord told us to eat bread and drink wine; if circumstances really prevent our doing that, let us do nothing, feeling that we are providentially hindered. Second, while any liquid, as water, might in some sort represent the blood of our dear Lord, yet it is obvious that wine much more clearly and strikingly represents it. Even if we did not perceive this, we ought to do just what he said; and much more when we do perceive it."
