Why do you ask this? (although I have nothing to hide, are you just curious or what?)
As far as transubstantiation, no of course not. John 6 does not teach that either. As far as the Gospel accounts – Jesus held up the bread and said This is my body given up for you (He didn’t make bread to have you eat your way to Heaven) do this (now He is referring to the bread) in remembrance of me.
Same as in Mattrhew’s account where they were repremanded by the Pharisees – for picking up and eating the grain – Jesus said that the food enters and gos through to the other end – it has no bearing in defiling anyone. It is from within that does that. So do you think that food which cannot defile a person can then make him, more righteous? NO!
