Deuteronomy 8:3
So He humbled you, allowed you to hunger, and fed you with manna which you did not know nor did your fathers know, that He might make you know that man shall not live by bread alone; but man lives by every word that proceeds from the mouth of the Lord.

Communion is one of those mysteries of God that I am willing to keep as a mystery. BUT - the focus on the physical eating of the bread (or the physical eating of Jesus’s body) is not the main point IMHO.
Just as in the Lord’s Prayer - “Give us this day our daily bread” is not about eating bread at all. It is the presence and word of Jesus in our lives.
And if you wish to keep it as a mystery that Jesus ordained as necessary for us, so be it.
It’s not about the eating of bread - as Jesus clearly repeatedly said, it’s about the eating of His body - a mystery no doubt. He calls it spiritual sustenance analogous to how manna was sustenance
