Coming in late, but wanted to comment:
Q11) To which laws do Christ's subjects submit themselves?
11 Just as prospective citizens of a country abide by the laws of their new land, Christ's subjects submit themselves to "the law of the Christ" by harmonizing their lives with all that Jesus taught and commanded. (Galatians 6:2) In particular, they loyally live by "the kingly law" of love. (James 2:8) What do these laws involve? prospective citizens
When does the WTS teach that JWs become full-fledged citizens; the anointed upon death and resurrection to heaven, the rest not until the end of the 1,000 year reign.
Good point. So, in actuality, JWs don't receive "everlasting life on a paradise earth" for obeying the Org. They receive a reprieve during Armaggeddon, but are still on trial for their lives until the final destruction of disobedient ones at the end of the Millenium.
Q12, 13) How do we loyally submit to "the law of the Christ"?
12) ... "If anyone has a cause for complaint against another," Christians loyally apply the law of the Christ by "putting up with one another and forgiving one another freely." Obeying this law helps them to keep overlooking imperfections and to find reasons to love one another...
The wording seems to be geared toward allowing the Society to call any sin it commits nothing more than "a cause for complaint". (i.e., if you complain about it, than it's something you could overlook if you were really forgiving.) Matthew 18:15-17 only applies to the R&F, I suppose. Try and apply it to the Org, and you violate the "principle" of "loyal submission."
