Protestant I suppose, but don't think it's just a symbol. Can I steal the rest of my answer from Martin Luther:
What is the Sacrament of the Altar?
It is the true body and blood of our Lord Jesus Christ, under the bread and wine, for us Christians to eat and to drink, instituted by Christ Himself.
Where is this written?
The holy Evangelists, Matthew, Mark, Luke, and St. Paul, write thus:
Our Lord Jesus Christ, the same night in which He was betrayed, took bread: and when He had given thanks, He brake it, and gave it to His disciples, and said, Take, eat; this is My body, which is given for you. This do in remembrance of Me.
After the same manner also He took the cup, when He had supped, gave thanks, and gave it to them, saying, Take, drink ye all of it. This cup is the new testament in My blood, which is shed for you for the remission of sins. This do ye, as oft as ye drink it, in remembrance of Me.
What is the benefit of such eating and drinking?
That is shown us in these words: Given, and shed for you, for the remission of sins; namely, that in the Sacrament forgiveness of sins, life, and salvation are given us through these words. For where there is forgiveness of sins, there is also life and salvation.
How can bodily eating and drinking do such great things?
It is not the eating and drinking, indeed, that does them, but the words which stand here, namely: Given, and shed for you, for the remission of sins. Which words are, beside the bodily eating and drinking, as the chief thing in the Sacrament; and he that believes these words has what they say and express, namely, the forgiveness of sins.
