1 Corinthians 10:17

seeing that we, who are many, are one bread, one body: for we are all partake of the one bread.

'we' -Christians universally.

'are one bread' -'Since there is one bread, we who are many are one body' (NASV)

Points to Note:

1. Paul isn't saying that you can only use "one piece" of bread on the Lord's Table. The "one bread" under consideration was shared in by all Christians in all areas. Paul said, "we who are many..for WE ALL PARTAKE OF THE ONE BREAD". Paul includes himself with the Corinthians as partaking of the 'one bread', and yet Paul wasn't. member at Corinth when he wrote this letter!

2. Paul's point is that all Christians partake of these same elements, especially the bread. This participation in the Lord's Table, demonstrates that you belong to the "one body". Note: Partaking of the Lord's Supper doesn't add you to the body of Christ, faith and baptism accomplish that. (1 Corinthians 12:13)

3. Again, all of this is being said to set up Paul's argument in verses 19-22. The Corinthians were trying to draw. false distinction between "participation" and "fellowship". They were arguing that they could participate in the temple feasts, without having "fellowship" with the false religion being celebrated. Paul says, does that make sense?
