Think about it, there are some people that believe the "presence" of Christ is spiritually discerned in the Communion elements, and there are others that demand that Christ meant it "literally", they will go so far as to say anyone who refuses to believe he/she is LITERALLY consuming real flesh and blood of Jesus cannot be saved. What I find the most confusing about this entire argument, is the ones who hold to literal flesh and blood, will be the first to try to explain that the elements don't really change into flesh and blood, but they, instead, remain the "accidents" of bread and wine, while mystically becoming the actual body and blood of the Savior. Now, I don't claim to be a scholar, but that sure as heck sounds like "spiritually" and NOT "literally". If the bread and wine do not miraculously change into human flesh and blood but remain for all eyes STILL bread and wine, then the obvious conclusion is that it is a spiritual belief. Is it pure stubbornness or is it blind obeisance that prevents some from admitting this?
Here is a Scripture that goes with the point you are making:
There are some who believe Christ’s words in John 6 and Paul’s writings in Corinthians (namely Orthodox, Copts, Catholics, Armenians, Ethiopians, Assyrians, Anglicans, Lutherans) and there are those who do not believe in Christ’s words in John 6(Calvinists)
