100% AMEN.........It is amazing how ignorance runs deep and people whine and cry like a 2 year old while judging "FRUIT" in error.....it is not unbiblical to call a spade a spade, use sarcasm, heat and or pointed derogatory names when identifying those that peddle false dogmas and error that leads to hell.....
It is not unbiblical to share the truth of God's Word and to go to a brother in private and share with him his fault between you and him alone in the spirit of meekness and love and prayer.
You have done neither except to call those who do not believe the same as you Satanic. What if you were the one in error and someone spoke to you this way. How would you feel and would you listen to those talking this way to you?
