Whether it was the writer’s intention it not, that episode was a perfect a analogy to a cold, lifeless Communist dictatorship. Landru was not a god, but a cult of personality, just like fat boy in North Korea.
E PLEBNISTA!
The Landru society, I think was ST’s version of Christianity. “The body” was the clue for me. I love TOS, but I think this one is glaringly obvious. Roddenberry was no Christian.
