St Thomas only believed in the Resurrection when he touched the Body of Christ: maybe this Eucharistic miracle will turn out to be your own touching of His sacred body.
May you be so blessed. Truly.
For most, but not all, the path to belief comes from Christ's words. There can be no doubt that He offers us His Body and Blood.
For instance:
I am the living bread which came down from heaven: if any man eat of this bread, he shall live for ever: and the bread that I will give is my flesh, which I will give for the life of the world.
Truly, truly, I say to you, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you.
Whoso eateth my flesh, and drinketh my blood, hath eternal life; and I will raise him up at the last day.
For my flesh is meat indeed, and my blood is drink indeed. He that eateth my flesh, and drinketh my blood, dwelleth in me, and I in him.
Christ the Son of God instituted the sacrament of the Eucharist - the Bread and Wine becoming His Body and Blood - at the Last Supper.
And he took bread, and when he had given thanks, he broke it and gave it to them, saying, “This is my body, which is given for you. Do this in remembrance of me.” And likewise the cup after they had eaten, saying, “This cup that is poured out for you is the new covenant in my blood."
If any corroborating evidence were needed, St Paul speaks about the Eucharist in Corinthians.
And when he had given thanks, he broke it, and said, “This is my body which is for you. Do this in remembrance of me.” In the same way also he took the cup, after supper, saying, “This cup is the new covenant in my blood. Do this, as often as you drink it, in remembrance of me.”
For as often as you eat this bread and drink the cup, you proclaim the Lord's death until he comes. Whoever, therefore, eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty concerning the body and blood of the Lord.
Many of us have read these words, and been given the marvelous grace to behold the Body of Christ through faith.
'Blessed are they that have not seen, but yet believe' isn't a throw-away line, but a roadmap of why God approaches us through faith, rather than just overwhelming our senses by His presence.
You said it yourself: He could appear visible to the naked eye at every Mass.
But He chooses not to. This matter is difficult for speech, but I believe He is growing our faith. Asking God to show that He is God is a temptation. It is a wicked generation that asks for a sign, and so on.
God leaves our free will free - to grow towards him in faith. He doesn't break the bruised reed. He uses the lightest of touches to move our hearts toward Him.
But nevertheless: God is God. He is free not to hide His majesty.
And today He is showing you His sacred body truly present in the Eucharist. On the other side of the world and through the lens of churchmanship that you have no taste for - but He is there.
May God bless us, and lead us into all truth.
It’s not flesh.
It’s not blood.
If, on rare occasion, a miracle occurs where it is - then it is rarely, and the rest of the time it isn’t.
Obviously it’s symbolic, because it’s not actually & always not.
