Notice that the WTBTS (and all of what is called Christianity" has established rules and regulations that THEY use to define who and what you are in relation to God and Christ! Christ did not establish any of these rules and regulations.
In fact, it was from such that Jesus freed his first 12 disciples from. He called them out of the domineering Jewish religious system of the day to himself as his disciples. (John 8:31-32)
What we see today is a reversion back to "law keeping." This time, men have established their own unique set of "rules, regulations and decorum" and enslaving men and women by them. There is no freedom of worship to the Most High God "without" following a set of rules and regulations. If one does not follow those rules - such as missing meetings or not putting so many hours each month in field service - one is somehow inadequate. This is from men!
It is really too bad that so many people have bought into the notion that they MUST belong to a system of religion to get to God or to please him. Jesus said something quite different at John 14:6. It would not be "through" other humans or their agencies that one would get to God, it would be ONLY by him.
Thus, our membership (discipleship) and attachment should not be to religious organizations, but to the "person" of Jesus Christ who is "The Way, The Truth and the Life."
And no other name has been given by God as to who it is we should be listening to and following. (Luke 9:35)
