But,
How can bread and wine become the flesh and blood of Jesus? Let us look at John 6:52-55, the Jews had a hard time believing Jesus' words as do non-Catholics.
(John 6:52-55) - The Jews therefore strove among themselves, saying, How can this man give us his flesh to eat? Then Jesus said unto them, verily, verily, I say unto you, Except ye eat the flesh of the Son of man, and drink his blood, ye have no life in you. Whoso eateth my flesh, and drinketh my blood, hath eternal life; and I will raise him up at the last day. For my flesh is meat indeed, and my blood is drink indeed.
(John 6:58), Jesus explains the importance of this bread, that He states that it is truly Himself. "This is that bread which came down from heaven; not as your fathers did eat manna and are dead: he that eateth of this bread shall live for ever." (This bread that Jesus speaks of, is the food that will give life)
In John 6:66 many of Jesus' disciples left Jesus because they could not believe in His words. Then Jesus says to His twelve apostles in John 6:67 "Will ye also go away?" It is clear what Jesus is stating, He does not take back His words and He does not say that it is another parable. He gives His apostles the opportunity to leave. Then Peter Simon, speaking for the 12 states in John 6:68, "Lord, to whom shall we go? Thou hast the words of eternal life.
Non-Catholics believe that John 6:53 is merely a symbol and not the actual presence of Christ. If Jesus were truly a symbol, then verse 27 through 29 in 1 Cor. 11 would not make sense. In this verse Paul states:

My priest also explained this last Sunday.(1 Cor. 11:27-29) "Wherefore whosoever shall eat this bread, and drink this cup of the Lord, unworthily, shall be guilty of the body and blood of the Lord." But let a man examine himself, and so let him eat of that bread, and drink of that cup. For he that eateth and drinketh unworthily, eateth and drinketh damnation to himself, not discerning the Lord's body.
Which goes to show, Mr. Coruscating, that you shouldn't butt into other people's expressions of faith if you don't know what religion your neighbor practices. Shame on you.
