Can a Church use more than one cup and still show communion?

Some large assembly gatherings use more than one cup. Is this scriptural or should this practice change?

The significance of the "one cup" is that it is "the communion of the blood of Christ" (1 Corinthians 10:16). When we partake of it, we are professing that the one ground of our fellowship with God is the precious blood of Christ. The "one loaf" of 1 Corinthians 10: is the emblem of the oneness of assembly fellowship. This is the greatest chapter in the New Testament dealing with the fellowship of an assembly. Verse 17 very likely means that the "one body" is the Corinthian assembly rather than the large aspect of the Body (Eph 1:22-23). In the three Gospel records of the institution of the supper and in the two passages in 1 Corinthians 10:16 and 11:25, it is important that "cup" is singular. Individual cups can never be construed as being a "cup of ... the communion of the blood of Christ." In Acts 2:41 and 4:4 as many as 3,000 and later 5,000 met together to break bread. I have never heard anyone explain how such a company could use only one cup in their remembrance of the Lord. "One cup" is most significant and we should maintain this principle to the best of our ability. When necessity demands that several cups are needed, we should not let this deteriorate into individual cups. It should still be "a cup of communion" or a common cup.
