Transubstantiation, now that shows diversity among denominations.
There is only one problem,Jesus Christ Himself had no intention of being the body and blood in physical form for this sacrament.
Christ used wine and bread,he did not cut himself or offer his flesh.
That happened one time only during his being Crucified.
Bible verse is clear :
Luke: 22. 17. And he took the cup, and gave thanks, and said, Take this, and divide it among yourselves: 18. For I say unto you, I will not drink of the fruit of the vine, until the kingdom of God shall come. 19. And he took bread, and gave thanks, and brake it, and gave unto them, saying, This is my body which is given for you: this do in remembrance of me. 20. Likewise also the cup after supper, saying, This cup is the new testament in my blood, which is shed for you.
He used bread and wine and said do this in remembrance of me.
He also washed the Apostles feet,are we to think He would be washing our feet?
There are Churches who practice the foot washing as well.
We are cleansed from our sin through Christ blood,with out his blood there would be no remission of sin.
Now look at God's law old and New Testament.
We are to abstain from drinking Blood.
Acts: 21. 25. As touching the Gentiles which believe, we have written and concluded that they observe no such thing, save only that they keep themselves from things offered to idols, and from blood, and from strangled, and from fornication.
