And of course, JWs are programmed to point to the "governing body" in Acts 15. Several points are noteworthy.
1) Paul is clearly not a member of the gb, yet more of his writings are preserved than any of the others.
2) The proceedings and debate are recorded for all to read with testimony and opinions presented by many different people. Why would the WT organization deviate from the early "organization" by keeping all their meetings private?
3) While the entire issue revolved around circumcision, the conclusion doesn't even mention the word. Rather, it leaves it to personal decision, specifically saying, "adding no further burden to you." When has the WT GB ever backed down from adding further burdens? (Get a degree... die at armageddon.) The decision was evidently so obscure that Paul, who had previously opposed circumcising Gentile Christians, in Acts 15 takes Timothy's penis in hand and circumcised him. That is some messed up leadership right there.
4) In that decision handed down in 49CE was the clear statement "... abstaining from things sacrificed to idols...." While WT today focuses on "blood" in the following part of the statement, what do we find about the seriousness of the word "abstaining"? 1 Cor. 10:25-30, Paul explains that eatting things sacrificed to idols is a conscience matter. Basically, he went against the "abstain" command and reduced it to "don't ask, don't tell." Could you imagine if a DO, CO, or elder wrote you a letter contradicting the GB, saying, "it's okay to take blood, just don't let anyone weak in faith find out."
When WT tries to point to a first century organization, it's all fiction. The conformity and clergy/laity structure didn't appear until the Church appeared. The organization WT is trying to emulate is the Catholic Church.
