ONLY the eternal love of God would drive and sustain Epikopos to take as much abuse as you guys dish out to him.
NO, Episkopos is an example of HOW MUCH ABUSE one must take from "so called believers" WHEN you truly LOVE GOD WITH ALL YOUR HEART, ALL YOUR MIND, AND ALL YOUR SOUL. And why does Episkopos take the time to explain so patiently over ALL these years knowing the abuse he'll receive?? ...because God put him here, because he has come to love and care for you knowing what awaits you and him if he doesn't speak up (think watchman), because God gives him all the "hard cases", since he himself was a "hard case." God knew that IF it was only ever christains Epi met, Episkopos would NEVER have become one. But WHEN Epi cried out to the Lord initially, GOD translated him into His kingdom, His eternal realm for 3 days until Epi wanted out...he (his self) couldn't take it. So, Epi also understands why you have a hard time hearing what he HAS to say.
His "superior teachings" (your words), actually come from his hours of time spent before the Lord. ...that's WHY you can't find them in any or all of the books you site. They are not from any books, they are from time spent before the Lord and what the Lord has given him. Yes, Epikopos IS INTENSE, but GOD EVEN MORE SO!
Abuse him IF you must, but you will answer to God for it. Matt 25:40 "And the King shall answer and say unto them, Verily I say unto you, Inasmuch as ye have done it unto one of the least of these my brethren, ye have done it unto me."
IF, even for a moment, you could "see" from another perspective (not your own) .... isn't that what the Lord gives us? ...a different way of seeing...everything becomes new...and our hearts are enlarged to be able to love as Jesus loves...no longer protecting SELF...
May the Lord bless you.
