I see you fancy yourself a fisher of men...
1 Do you now reject all of the wts teachings and doctrines?
I reject all teachings I judge as being bullshit. That would mean most of the WBTS teachings as well as many generally Christian teachings and teachings of other religions. At this point, I daily consider "Do what thou Wilt shall be the whole of the Law, Love is the Law, Love under Will" as primary.
2 What doctrines do you still believe in?
Doctrinally? Practically nothing. And I only say practically because nothing comes to mind, but there could be something, somewhere. I don't intend on putting too much thought to it.
3 What doctrines have you stopped believing in?
See 2.
4 What doctrines are you not sure about?
Again, see 2.
What are you trying to accomplish here?
