I'm not sure exactly how the Anglicans/Episcopalians view the Lord's Table, but I can summarize a few things that I know for certain many protestants believe.
1. Jesus instituted the Lord's supper as 1 of His 2 ordained sacraments (ordinances) for the church administer until He returns.
2. That as an ordinance, the Lord's supper is a visible sign of the gospel of Christ-
The bread represents His body which was given for His people.
The wine (fruit of the vine) represents His shed blood poured out for His people.
Each time we partake of the supper we see, touch, smell, and taste a representation of the gospel.
3. The bread and wine given in the supper remain just that, bread and wine, and undergo no change whatsoever. (*I know that Lutherans would disagree with that statement, being that they adhere to the consubstantion theory),
4. Although the bread and wine remain bread and wine, yet they are special because they were set apart by Christ for holy use. And because of this, only bread and wine (or grape juice) should be used in the supper, i.e. pizza and pepsi would not be acceptable.
5. Again, although the bread and wine remain just that, the fact that Jesus commands that we must eat of His flesh and drink of His blood reminds us that we are commanded to consume the gospel by faith, to eat it, to partake of it richly. Yet this is in the spiritual realm, not in the flesh.
6. We partake of the supper in remembrance of Christ, using it as a time to reflect on Him, His Word, and how He has impacted our lives by the cross.
7. The supper is not to be taken in a flippant or irreverant manner. Repentance is a necessary prerequisite by the command of the Apostle Paul.
Therefore the table is in no means to be taken by the non-believer, lest he heap up wrath upon himself. The same applies to unrepentant Christians engrossed in blatant sin.
8. Even with the extreme reverance that must be involved in the supper, yet still, all the more it is a time of rejoicing, knowing that Christ is our Passover Lamb.
9. The table is the Lord's table. Not the table of a particular church, a particular denomination, etc. It is His table. And when we dine at His table we are reminded that one day we will sit with Him at the greatest banquet of all, the marriage supper of the Lamb.
I'm sure there's plenty I left out.
I did not use Scripture quotations for the simple fact that they all would have come from the same passages in Matthew 26 and 1 Cor. 11.
Again, that by no means is all that the Lord's supper is, but I think it's a decent, although small summary.
Grace and peace.
