I could be Mr. Green and, due to mistrust considering the times and what is happening, study with the JWs as Mr. Brown.
Get baptized as Mr. Brown.
Become one of their congregation elders as Mr. Brown.
Etc. Etc. Etc.
All this since I am not required to provide any signature and/or document to identify myself as Mr. Brown.
Are they complying with human law? But which law?
Honestly, the more I think about it, the less I understand this aspect...
