The Real Presence is not a “minor point”.
If you take the Bible at its word, it says that the Body and Blood is Christ is in Communion.
Now we can argue till the day is done about how, but it is very difficult to say one believes in what the Word says and then disregard it when it doesn’t fit our sense of logic. Bad things happen then.
I say it is minor because communion is not required for salvation. Is partaking in communion required to enter the presence of God?
