Christianity has two incomprehensibly profound Mysteries. The Blessed Trinity and the Most Holy Eucharist, Catholic Holy Communion, where Christ Himself is made “Truly, Really and Substanually Present; Body, Blood, Soul and Divinity… The COMPLETE Christ. The Theological term describing this act is “transubstanuation.”
This is PURELY and Solely a Godly Miracle.
From God the Father
Of God the Son
By God the Holy Spirit through by God’s choice, the hands of His Catholic priest. “Do this in memory of Me.”
What is often not understood in the “error of the deserters” John 6: verses 28,30,41-42, and 61. They assume in ERROR that Jesus was speaking of His Cardinal body. NO! Jesus speaks here of His Glorified, Risen and now Perfect Body. A body very real but at the same time Devine; able to pass through walls and locked doors.
As a FYI: this was clearly understood by Peter and the Apostles, who when Asked by Christ: ‘Do you wish to call me a liar and desert Me too” replied: John 6: 68-70 “ Then Jesus said to the twelve: Will you also go away?  And Simon Peter answered him: Lord, to whom shall we go? thou hast the words of eternal life.  And we have believed and have known, that thou art the Christ, the Son of God.”
This belief is born out in Matthew 26:26-28; Mark 14: 22-24; Luke 22:19-21 and Paul in 1st. Cor. 11: 23-29.
So we have the testimony of God Himself and FIVE authors of the Bible. Amen!
Genesis 1:29 where it was God ORIGINAL plan for humanity to not eat meat. This is changed by God after the Flood and the Burnt Offering Noah made to God of all “clean living animals”: Gen.9: 1-4 “And God blessed Noah and his sons, and said to them, “Be fruitful and multiply, and fill the earth. The fear of you and the dread of you shall be upon every beast of the earth, and upon every bird of the air, upon everything that creeps on the ground and all the fish of the sea; into your hand they are delivered. Every moving thing that lives shall be food for you; and as I gave you the green plants, I give you everything. Only you shall not eat flesh with its life, that is, its blood.”
God Bless you,
