What could Satan possible gain by even proclaiming such a message?
Satan gains the sowing of tares into the real church through the gospel of tare sowing! But, not to be overly concerned about it, the Lord intends to burn them.
The problem codie is raising any human messege to inspired status.
Remember Satan in the garden only "slightly" misquoted God.Error does not have to be 100% evil to be error or cause you not to look at the Christ of the Bible ..it only has to vary slightly .In this case Christ lives in me...the bible tells me that.
John 14:20 At that day ye shall know that I [am] in my Father, and ye in me, and I in you.
I do not need to go to communion to united with Christ.."a small misstatement" but important error IMHO
