Read some... skimmed some... apologies if I repeat what has been said.
To a large extent I think Roddenberry was ahead of his time/a bit too early with his views on religion. He himself may not have seen, thought about or felt/agreed with the complete outworking of his philosophy. He married Majel in a traditional Buddhist-Shinto ceremony. For him to do this tells me he wasn't COMPLETELY against religion. I conclude from this and his Star Trek writings that he viewed religion as something that helps establish ritual and custom in our lives; that religion should be fluffy and decorative. Perhaps he even agreed that religion has been a necessary advocate in basic human morality such as love of neighbor, thou shall not kill, etc...
The world of the 1960s definitely wasn't ready for a completely anti-religious show. Hence we have TOS implying a favorable view of Christianity (Bread and Circuses, Dagger of the Mind, Gem) and other non-Christian religions highlighted in TNG, as noted above.
Here is what Roddenberry said:
We must question the story logic of having an all-knowing all-powerful God, who creates faulty Humans, and then blames them for his own mistakes
A lot of people have reached this conclusion based on the evidence at hand. Unfortunately the evidence is biased and skewed. God did not create faulty Humans and then blame them for their own mistakes. God made perfect Humans that chose to exercise their free will.
It's obvious from history and all the evidence at hand that FALSE religion is to blame for a lot of man's woes. The emphasis here though is on the word FALSE. All of the problems everyone here has pointed to in regards religion can be traced back to the failure of the religious leaders to follow their own holy scriptures.
For example, we don't view the United States or United States laws as being wrong or evil simply because many US citizens choose to commit crimes. Nor do we ignore the United States laws and regulations simply because we see corruption among the leaders. The laws are sound. The US is a great country to live in; we simply know better than to trust or follow government leaders or prominent citizens (athletes, community pillars, etc...) when we see them violate the law. When this happens we choose different leaders, we don't totally reject the country.
The same standard should be held in regards religion. When the leaders do wrong, commit evil, abuse or mistreat the flock; when prominent, upstanding members of the Church get caught in obvious in wrongs; then it's time to reassess the direction we're heading and find leaders that will take us where we want to go.
I agree with you! But unfortunately it's going to take a lot longer than a couple of thousand years to work religion out of society. Look at us still today...some humans are terribly repressed by religion and we're still fighting over who's God is the right God. We don't learn from our past so we're bound to relive it. It's very sad really....but I agree that one day there will be no religion -- we are just waaaaaaaay ahead of our time!
Actually, we're much closer than you think. I firmly believe we'll see such a move within your lifetime. The fact we're having such open debates about this subject, the fact we see comments critical of religion in daily episodic television and movies, the fact we see billboards promoting the anti-religion belief strongly point to the conclusion Religion is on the way out. Can you imagine such debates taking place 1,000 years ago? 100 years ago? 50 years ago?
It might take another 5, 10 or 20 years. Heck it might take 50 more years but we're very close to all of this coming to pass.
False Religion is a snare and a racket.
