Ezek 3:1-3 "Then he said to me, 'Son of man, eat what you find; eat this scroll, and go, speak to the house of Israel.' So I opened my mouth, and He fed me this scroll. And He said to me, 'Son of man, feed your stomach, and fill your body with this scroll which I am giving you.' Then I ate it, and it was sweet as honey in my mouth.
Jesus is the fulfillment of the OT, the only Word which gives life. The one sacrifice that takes away the sins of the world.
All that came before Him was in preparation for Him.
Just as He came truly in the flesh, flesh which suffered for our redemption, He is truly in the Eucharist.
“Man does not LIVE by bread alone, but by every word which proceeds from the mouth of God.”
Jesus is the Word which is the Bread of Life.
These are the mysteries of our faith. We cannot know how God has done these things, but we trust in Him who created all things and in whom all things continue to exist.
