Ah, so we have arrived. I wondered how long it would take you to get to saying something like, "God can do whatever He wants to do."
I point out that what your earlier quote said went very, very far beyond what God Himself inspired in Scripture.
Now you have come back to the Words of Christ and stopped at one phrase.
Christ also said He was a door. If He wanted to turn Himself into a door, I guess by this argument, you will believe, right? He also said, I am the true vine. Guess you will believe He is really a vine, right?
There is an entire collection of inspired writings you must study to understand what was said and how the Apostles understood it. They were in the room, as you point out. Yet there is no evidence in Scripture that they ever had priests, ever turned bread and wine into body and blood. Never commanded. No example of this being replicated or believed.
I am always a bit astounded when someone turns their nose up at studying God's Word and happily substitutes the words of mortals. But then, that used to be me too!
The hour is so dark that the light of TRUTH is not seen by those whose pride in their ‘fidelity’ to their institution is all they know. You cannot reason such an one to open their spirit to GOD. They are lost to magic thinking: ‘god can do anything, so he does the magic our institution declares to us.’ Such a mind cannot discern truth.
Do you not believe what the angel Gabriel told Mary, that with God all things shall be possible? I do. I also believe what Jesus tells us. And Jesus did tell us that the bread He took and blessed was His body.
If you want to believe that He was being symbolic, by all means, go ahead. I believe He means it when He says the bread that is given us to eat is His body.
