In various threads on this sub-forum we read of certain “essentials” required in order to properly call oneself a “Christian”; i.e. belief in the Trinity, the bodily resurrection of Jesus, etc. Outside of the Catholic and Orthodox churches, with the exception of possibly some Lutheran and Anglican communities, the Eucharist is not even on the list.
I bring this up because for Catholics and Orthodox, the Eucharist, properly defined as the true presence of the body, blood, soul and divinity of Christ, is the “source and summit” of our faith. To say it is an “essential” belief is an understatement. If there was no Eucharist, there would be no Catholic Church and therefore no Protestant communities as well.
So the question: Is the Eucharist essential to Christianity? If not, why?
