Transsubstantiation is straight from the gospel of Luke, see the supper at Emmaus episode.
In Luke 24, the Sovereign Lord chose to hide himself from their recognition and then reveal Himself as the Master of the meal. The spirit is wind, no one knowing from whence it comes. God does not need to hide the spirit in bread for us to consume it. If this life changing bread has the power you attribute to it by relating this story, why is Christ not effectual for ALL that receive the rcc host? I'm sorry, but Christ's call is effectual 100% of the time. Christ does not fail.
If Christ really wanted people to eat His flesh and drink His blood, don't you think the last supper would have been an ideal time for them to consume them?
He said, “do THIS” in memory of me. And what was He doing at the EXACT moment He said, “do THIS”? He was breaking bread and drinking wine. He made no indication that anything had been transformed. He was still man. His flesh was not separate from His body at that time, nor His blood. THAT experience was the ‘THIS’ He talked about. Now that the rcc pretends the bread and wine are actual flesh and blood of Jesus, they are not doing the ‘THIS’ anymore, but something different and NOT according to His instruction. By necessity then, the rcc misinterpretation that now ADDS some magical priest necessitating conversion of material.
Was the little metal cup the ‘New Covenant’ too?
