How many cups should an assembly use at the Lord's Supper?

Is it not as much a departure from the scriptural practice to use two or so cups at the Lord’s table, as it would be to use fifty-two?

Though the unity of the cup is not insisted upon in the Scriptures in the same way as that of the loaf, which in 1 Corinthians 10: represents the one indivisible Body of Christ, nevertheless it is always “the cup” that is spoken of—the unique receptacle of that which represents the blood of Christ. But even in the case of the loaf, as each member present partakes, the outward unity of the loaf is not preserved. Indeed, even before that, as the brother who gives thanks, breaks the loaf, and for convenience places the portions on different plates, the figure of the unity of the body is in no way affected, as it would be were the loaf originally cut up in in bits. No more would the unity of the cup be, even though it stood on the same ground as the loaf, by being poured into different glasses or cups, for convenience of distribution. It is still “the cup,” each being filled from the one original receptacle. But by the introduction of what is called “the individual cup” for each “communicant,” the receptacles are multiplied and the identity of the wine in them is completely lost and the thought of fellowship hindered. As we practise it, though there be two or more cups, for purposes of distribution, all are filled from the original receptacle and still constitute “the cup”—the communion of the blood of Christ.
