Thanks for making my point. Your position (that the "worldwide preaching work" is an identifying mark of "God's organization") depends on today being part the Last Days. Stated another way, if today is not part of the Last Days, then the existence of a "worldwide preaching work" is just as irrelevant now as it was in the 1400s.
I'm well aware that your clergy (the WT Society) teaches that we're in the Last Days that began in 1914. If they're wrong, then the existence of a "worldwide preaching work" is irrelevant.
Hence, my point about the Catholic church in the 1400s. Don't you agree that if someone who, in 1400, figured out that some Catholic teachings were false, should have left the church, even if there was not another worldwide organization to join? Some did so, and were persecuted for it. I think they did the right thing, even though they did not join a big religious organization with a "worldwide preaching work." Why should today be any different?
