Protestant ministers have no apostolic authority, they simply oversea a mimicking of the Sacrament of Communion not the sacramental representation of the one time sacrifice of Jesus Christ that can only occur with valid apostolic authority through the laying of hands by those who have received that authority to do so.
Since in a protestant gathering it can only remain a piece of bread, anybody should be able to grab a piece..except for a Catholic or Orthodox Christian who understand St. Paul's admonition:
For I received from the Lord what I also handed on to you, that the Lord Jesus, on the night he was handed over, took bread, 24
and, after he had given thanks, broke it and said, "This is my body that is for you. Do this in remembrance of me." 25
In the same way also the cup, after supper, saying, "This cup is the new covenant in my blood. Do this, as often as you drink it, in remembrance of me." 26
For as often as you eat this bread and drink the cup, you proclaim the death of the Lord until he comes. 27
Therefore whoever eats the bread or drinks the cup of the Lord unworthily will have to answer for the body and blood of the Lord. 12 28
A person should examine himself, 13 and so eat the bread and drink the cup. 29
For anyone who eats and drinks without discerning the body, eats and drinks judgment 14 on himself.
In the same way also the cup, after supper, saying, "This cup is the new covenant in my blood. Do this, as often as you drink it, in remembrance of me." 26
Read the words you wrote....
THIS is my body; THIS cup is the new covenant.
Specific items that the Lord handled. Unless you claim any bread or wine can be used? But in that case are we not ignoring the words of the Lord by using the wrong items, the wrong ingredients? If it is to be literal, then make it completely literal. Otherwise it is symbolic.
Read more: Do this in remembrance of me. The Lord's OWN WORDS are to repeat as He did to REMEMBER Him. We are not given power or command to transubstantiate the host or the wine; we are commanded to repeat the sharing of bread and wine to REMEMBER His sacrifice to us.
The words you quote define this, in extremely plain and clear language. Remembrance - it's even stated during each mass. It is a reflection, not an action.
The Anglican/Episcopal churches at least, and I think also the Lutherans, claim valid apostolic succession, and I believe that this is recognized by Rome.
