In terms of biblical references, there are many, starting back in the OT- from the Pascal Lamb/Passover in Egypt and the manna in Exodus; a few more elsewhere that escape me right now.
The tough passage is John Chapter 6, roughly verse 35 to the end of the chapter. Jesus said “unless you eat my body and drink my blood you cannot have life within you”. Jesus let many disciples walk away; even asked Peter “will you leave also?”...
Pretty strong stuff. Jesus was pretty clear, as he said the same thing several times.
Luke 22:19 is the Last Supper; where Jesus gives Himself to the apostles under the form of bread and wine, and tells them to do likewise. It's in the other gospels also.
Catholics believe that Jesus loves us so much that He wanted to remain with us until the end of the world. He would have remained suspended on that cross to stay with us, but would have then been limited to one dark corner of the planet. In the Eucharist, He is where we are, all over the world. Reminds one of the multiplication of the loaves and fish, another prophecy of the Eucharist.
Jesus let those people go because He knew no matter what He said, they wouldn't believe Him...
Joh 6:64 But there are some of you that believe not. For Jesus knew from the beginning who they were that believed not, and who should betray him.
Catholics believe that Jesus loves us so much that He wanted to remain with us until the end of the world.
With all due respect, Jesus gave Himself to us in the form of the Holy Spirit to be with us til He comes again to take us home...
Joh 14:16 And I will pray the Father, and he shall give you another Comforter, that he may abide with you forever;
He would have remained suspended on that cross to stay with us, but would have then been limited to one dark corner of the planet. In the Eucharist, He is where we are, all over the world.
Jesus objective was to be Resurrected...No, he wouldn't have stayed on the Cross for Catholics to gather and worship His dead, broken body...
That's the difference between believing the propoganda your church puts out and what God told us in the scriptures...
It doesn't matter to me what you people believe but scripture means nothing to you guys...
All you can do is cut and paste the propoganda and selected bible passages that your church demands you use...You can't respond to scripture other than what your church has programmed into you...
