Hi His Excellency,
I'm envious of anyone who communicates in more than his / her native language. I along with everyone on this forum are very proud to hear such an eloquent new one. Welcome.
Until you tell us more about yourself it's hard to put the pieces together. But that's okay. I gather, however, that you are more seasoned than new as far as JW's go. You are exploring (finding answers) and not limiting yourself to Watchtower publications.
I did that same thing some 35 years ago and have never regretted it. That without the help of the internet. I explored and found answers then but it was tough at times.
Nowadays I love it when they call. I always get a chance to divulge the fact that I studied with them many years ago. Not a lie -- I simply don't expose the fact that I then became a MS, an elder, then developed a bothered conscience that resulted in disfellowshipping.
Their inevitable question -- "Why did you stop studying?" -- is the perfect lead to my introduction to The Great Watchtower Contradiction, an 11 minute read designed for new ones but which poses questions on topics that the most seasoned JW would cringe at.
Contradiction contains a table handout that you can snip for purse or billfold. I always keep my billfold handy.
I wish you the very best.
Len
