Sure, you can do that...But you can't stop there...You have to look in the context of those verses you state...
Joh 6:33 For the bread of God is he which cometh down from heaven, and giveth life unto the world.
So the wafer and wine you eat/drink at your church gives life to the world??? Is that the salvation Jesus offered???
And compare
Joh 6:35 And Jesus said unto them, I am the bread of life: he that cometh to me shall never hunger; and he that believeth on me shall never thirst.
Are you saying you no longer hunger or thirst??? That's the context...
Here's some more context...
Joh 6:40 And this is the will of him that sent me, that every one which seeth the Son, and believeth on him, may have everlasting life: and I will raise him up at the last day.
Have you ever seen Jesus??? Do you see Jesus when your priest turns that little cookie into Jesus??? It says here all you have to do is look at Jesus and believe on him and you'll be raised up in the last day...You don't have to eat the cracker...What a contradiction is this???
But you take one or two verses, totally ignore the context and build a Religion and a Magisterium on it...
and then report back with what you believe you have read.
I know what I read...And I know what you didn't read...
Joh 6:58 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 forever.
Interesting verse...But what Jesus DID NOT SAY is; This is that bread which came down from heaven: not as manna, but what He said was not as your fathers eat...>p>
Jesus is the spiritual manna...
Joh 6:63 It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life.
