“If He gave both on the cross, then there is no FLESH AND BLOOD left to give any more.”
Sure there is - He’s God and resurrected.
“Flesh and blood cannot inherit the kingdom of God.”
No, but we will have resurrected bodies in Heaven so obviously glorified flesh will be coupled with sanctified souls.
“The body Jesus has now is not a flesh and blood human body, the kind that is designed to live on earth, because that body cannot handle any environment outside of a narrow range of conditions even here on earth.’
It’s flesh - just glorified flesh.
“His blood was shed (past tense), poured out (past tense) for many, and is gone.”
Glorified, not gone.
“Whatever blood Catholics think they’re drinking, it isn’t Jesus’.”
Yes, it is - exactly as He told us.
You get an A for doggedness.
As far as theology that makes any sense, that’s a different story.
