Eucharist and Statues

Protestants reject the Eucharist as being actually substantially Christ's body and blood and opt for a symbolic view on the basis that eating blood and flesh of man is forbidden by the laws of Moses, therefore it would be "unclean" for Christ to actually do this. 

However, Protestants generally make another argue that's unrelated about statues and images. They say the Laws of Moses forbid making statues and graven images in Exodus 20 in the 10 commandments, then say it does not matter that Exodus 25 has God ordering Moses to make a statue of angels on the ark, since its an exception and God specifically gave him orders to build it, so its ok for Moses.

Now, if we are to apply this reasoning to the Eucharistic debate their logic backfires on them.  They would have to admit that despite God prohibiting eating flesh and blood in the Law, that if God (in the person of Christ) instructs people to eat His flesh and Blood, then it is lawful and must be done, since orders were given to do precisely that. So the Protestant's symbolic view of the Eucharist on the basis of prohibition of blood backfires on them and shows they have a double standard.

Thou shalt not make unto thee a graven image, nor any manner of likeness, of any thing that is in heaven above, or that is in the earth beneath--Exodus 20:3

And thou shalt make two cherubim of gold; of beaten work shalt thou make them, at the two ends of the ark-cover. --Exodus 25:18

But be sure you do not eat the blood, because the blood is the life, and you must not eat the life with the meat.--Deuteronomy 12:23

 unless you eat the flesh of the Son of Man and drink His blood, you have no life in yourselves.--John 6:53

Law                                                                                      God's "special instruction"
Don't drink blood (Deuteronomy 12:23)                             "Drink my blood" (John 6:53)
Don't make a graven images (Exodus 20:3)                        "make two cherubim of gold"(Exodus 25:18)

Furthermore, the law explains why not to "eat" the blood, because the "blood is the life" and Jesus said you must drink His blood to have life!

Also, some explain the commandment to drink His blood as a symbol that they are no longer bound to the laws of Moses but under a new covenant with new promises.

*Also Acts states:

avoid pollution from idols, unlawful marriage, the meat of strangled animals, and blood--Acts 15:20 (some debate if drinking blood is alluded to here at all, some believe its an expression for violence)

Regardless, if we are to accept the Protestant reasoning that a specific commandment may be an exception to a general rule, then even if Acts 15:20 addresses drinking blood, it does not matter since a specific command was given to do it in a special case with Christ.
