I take exception to YOUR exception.
Scripture states clearly that it is both.
Therefore, because Jesus rose from the dead, and he laid his stamp of approval on it, being, you know, GOD, I believe it.
Don’t ask me how it’s true because I don’t know; I only know it is.
This is just illogical and inconsistent.
Jesus' Blood cannot have been shed at the Last Supper, then at Calvary, then at every instance of the Remembrance supper. It was shed once for all, as was His body given once for all. Read Hebrews 9:23-28 thru 10:14 again. If it doesn't sink in, again. And continue until you have confidence in your sin-debt being paid once for all time, forever, and go forward living in freedom from guilt as well as from the burden of erroneous interpretation of the Scriptures respecting this matter.
Believe me, I hate to have to say this, but you need to rethink your position on this affair, else we cannot have unity of thought in any dimension of the four ordinances particular to the Christ-centered disciple.
Reality shows that Jesus' inauguration of this memorial requires the emblems of the real consequences of His one-time suffering for our sins had to be symbolic, His words in figurative-literal meaning, not plain literal. Neither can you certify why you think they are not symbolic.
And why the disciples, trained in interpreting His parables, and not yet having experienced or imagined the events to shortly occur to the Messiah they thought was (but was not) about to establish His earthly Kingdom--why would they not clearly assume that this was symbolic in nature? Did they truly eat roasted flesh (no)? drink freshly drawn blood (no)? They would have spit it out if they thought it was human substance. Like the ritual of water baptism, they obviously must have thought that it was symbolic in nature.
Anything else would have been insane and enslaving, not intelligent and freedom-granting.
