That is a good example of your failure to navigate or actually understand the scriptures. Here is what is really true--full of symbols, and breaking all "literal fleshly, worldly" bonds:Manna from heaven is not symbolic; it’s literal fleshy, worldly, food for the sustainable of people her and now on Earth (at the time it was given.
Then Jesus said to them, “Most assuredly, I say to you, unless you eat the flesh of the Son of Man and drink His blood, you have no life in you. Whoever eats My flesh and drinks My blood has eternal life, and I will raise him up at the last day. For My flesh is food indeed, and My blood is drink indeed. He who eats My flesh and drinks My blood abides in Me, and I in him. As the living Father sent Me, and I live because of the Father, so he who feeds on Me will live because of Me. This is the bread which came down from heaven—not as your fathers ate the manna, and are dead. He who eats this bread will live forever.” John 6:53-58
...And if you noticed--He altered the meaning of manna to a "higher spiritual meaning."
