Eucharist/communion/Shulchan Adonai is
very important. It is also indissolubly linked to Passover.
In the Passover Seder, we are to consider
ourselves as being present in the liberation from Egyptian slavery. In communion, we consider ourselves to have died and risen with the Lord.
Being bread and wine, it is a covenant meal - meaning that those who partake together have a certain spiritual linkage together. Indeed, IMO many misinterpret this verse:
1 Corinthians 11:27
Therefore whoever eats the bread or drinks the cup of the Lord in an unworthy manner, shall be guilty of the body and the blood of the Lord.
We think of that as dealing with personal sins, and that is all well and good; but actually does not fit the greater context of the epistle. In the very next chapter we read this:
1 Corinthians 12:27
Now you are Christ’s body, and individually members of it.
"Communion" (koinonia) means to have things in common. I submit that the "body" Paul wrote about was the local body of believers, and the sins that made communion taking "unworthy" was unresolved hurts and disputes.
So if we look at the Passover symbology - we are part of a great throng coming from bondage to freedom. If we look to the New Covenant symbology - we are covenanting ourselves with our fellow believers to walk out the New Covenant. Either way it is NOT an individual thing.
