Personally, I am filled with awe every time I witness the miracle to which I assume you refer. It is actually a double miracle. The first is that the bread and wine are transformed into the body, blood, soul and divinity of Jesus Christ. The second miracle is that the Body of Christ and the Precious Blood retain the appearances of bread and wine so that we will be able to receive them comfortably. Thank you Jesus!
The “Eucharistic miracles” wherein the host actually displays the characteristics of human flesh (always heart muscle, blood type AB positive), or the Precious Blood displays the characteristics of human blood (again always type AB +) are really only half a miracle. The second half of the miracle is withheld, for whatever reason the Lord has determined.
This is only one of the miracles this Catholic has experienced. Another is my son’s miraculous conversion from atheism to Catholicism that completely changed his life. Again, thank you Jesus!! I love you more than I can say!!
God bless,
Paul
