I never knew why the WTS emphasized the Memorial, especially for non-anointed people. Non-anointed jws were not even invited and made to feel they had to or should be there since they were not in a "covenant arrangement" with Jesus. 1925 95,000+ 1928 44,000+ (or 23,000+ depending on the quote) In fact the WTS believed that the "great crowd" also called "great company" or "great multitude" would go to heaven. https://www.jwfacts.com/watchtower/great-crowd-other-sheep.php This was changed over time by the WTS to the great crowd only living on earth and not anointed. "No Scripture states that either the Great Crowd or Other Sheep are on earth. Christians understand the Great Crowd have a heavenly hope, as did Pastor Russell, and even Rutherford for many years.
"Does the Great Company receive life direct from God on the spirit plane? Answer -- Yes, they receive life direct in that they have been begotten of the Holy Spirit, and when they are begotten they are just the same way as the little flock, because we are called in the one hope of our calling. They do not make their calling and election sure, but not being worthy of second death, they therefore receive life on the spirit plane." What Pastor Russell Saidp.297
