smiddy3,2
"Even casting Satan down to earth" is no comparison to Disfellowship because "earth is the footstool of Jehovah." (Isaiah 66:1; Mathew 5:35)
And also, since Jesus traced all evil's source to the human's heart (Mark 7:21-23) Satan should be understood figuratively (can't be a literal person) as old Bible Translations (such as KJV) puts "the whole world lieth in wickedness." (1/1JN.5.19.KJV) The same word is used for "bad fruits" (Mathew 7:17) and for eyes that are distracted (Mathew 6:22, 23)
