From what I hear there are a lot more people that show up for the so-called letter writing and telephone witnessing parties than Saturday morning field circus. You pretend to make a few calls and write a few letters you’ll never put in the mail, eat cake and drink coffee while talking loudly with your group. It’s basically the new book study and it is causing more cohesion to the organization as a result.
They may have lucked themselves into the best situation to stop the bleed at least temporarily and become a more mainstream accepted religion, they’ve long been de-emphasizing the craziest parts (blood, 1914, Armageddon) and becoming a boring regular Christian religion.
COVID gives them a good excuse to get rid of many of the extremist Rutherfordian and Franzian practices, including the vaccination policy they are promoting which now gives them a chance to pivot to a more mainstream view on abortion, blood and other medical practices. COVID vaccination production, had it happened ca 1980, if you read the blood brochure and other medical instructions until the early 2000s, would have been considered a violation of all sorts of biblical interpretations of theirs, I clearly remember the elders giving us a list of approved and non-approved vaccines because they used humane or animal blood or aborted fetus in their production, it even listed why we rejected a particular medicine, but the current COVID vaccines all did one or more of those things and they’re just ignoring that fact.
