It is not an organism confined to a cardiovascular-pulmonary-nervous-musculo-skeletal system stuck at 98.6oF. and limited to limbs, sense organs, genitals, hair, ears and all the other outward physical features constituting Jesus' biological limits. What It is, is His REAL, Resurrected Body, without limits and not just a symbol.
After the Consecration, it retains the appearance of bread and wine, but it IS, in truth, Himself: the same Body that was a tiny zygote in the womb of His Virgin Mother; the same Body that died on the cross, was laid in the tomb, and rose on the Third Day; the same Body that is seated at the right hand of the Father in Glory. Unlike before the crucifixion, His body is now transformed and limitless.
When you consume the Eucharist, you are consuming His real flesh and blood: you receive Him in the fullest way imaginable, and beyond what the mind of man can imagine. I repeat: absolutely limitless.
He says "This is My Body."
I say "Amen."
That about sums it up.
Later; after it was all over; dogs were at the foot of the cross; lapping up the blood and water.
