Yes it should…because the New Testament teaches it and the early church made it a point upon which to err was grave heresy. Look again at what Ignatius of Antioch tells the church at Smyrna and the what St.Paul says in 1st Corinthians 11:23-30.
1st Corinthians 11:23-30
"23 For I have received of the Lord that which also I delivered unto you, that the Lord Jesus, the same night in which he was betrayed, took bread. 24 And giving thanks, broke, and said: Take ye, and eat: this is my body, which shall be delivered for you: this do for the commemoration of me. 25 In like manner also the chalice, after he had supped, saying: This chalice is the new testament in my blood: this do ye, as often as you shall drink, for the commemoration of me.
26 For as often as you shall eat this bread, and drink the chalice, you shall shew the death of the Lord, until he come. 27 Therefore whosoever shall eat this bread, or drink the chalice of the Lord unworthily, shall be guilty of the body and of the blood of the Lord. 28 But let a man prove himself: and so let him eat of that bread, and drink of the chalice. 29 For he that eateth and drinketh unworthily, eateth and drinketh judgment to himself, not discerning the body of the Lord. 30 Therefore are there many infirm and weak among you, and many sleep. "
If there is no real presence in the Eucharist, then how can St.Paul warn us not to take it unworthily lest we become guilty of the body and blood of the Lord? That “spiritualization” makes complete nonsense not only of the 6th chapter of John, but of 1st Corinthians 10:16-17 “16 The chalice of benediction, which we bless, is it not the communion of the blood of Christ? And the bread, which we break, is it not the partaking of the body of the Lord? 17 For we, being many, are one bread, one body, all that partake of one bread.”
Now, how can one become guilty of the body and blood of the Lord IF THAT BODY AND BLOOD OF THE LORD IS NOT REALLY THERE? Now if I make a symbol of a person and then I decide to do bad things to that symbol. I may indeed be guilty of abusing that symbol of the person, but am I guilty of his body and blood? Silly question…of course not! Why? BECAUSE THAT PERSON IS NOT REALLY PRESENT IN THAT SYMBOL is he?
