@Teary: The interpretation of JW's of those scriptures is far different (far more extremist) and very much out of context than most scholars and even the historical first century Christians.
Read the whole book and then tell me, to whom was this written to, who was he talking about and also take into context similar verses in other books and does that match the description that current-day JW's give to EVERYONE that is NOT ACTIVE IN AND NOT IN FULL AGREEMENT WITH EVERYTHING the WT organization and the Governing Body (not the Faithful & Discreet Slave) says?
The bold parts are important as that is what JW's think an apostate against Christ is. Were there not disagreements in the 1st century? Were there not different substreams in the Christian congregations? Was there ANY evidence of a CENTRAL GOVERNING BODY going over EVERY SINGLE DETAIL of the faith and doctrine?
