Little to no political influence, except where relevant.
Small handfuls of worship buildings scattered throughout the world.
Mostly populated with home practices and small study groups.
Religious clergy and institutions being completely optional.
Do you think it would make it better in terms of minimizing potential civil, religious, and political abuses and power grabs? Or would it make everything worse trying to track them down?
Excellent questions! I expect this to be a very fun and thoughtful thread.
Just to give context, I don't push organized religion. It's not for everyone.
I would also preface this by saying that small groups are just as organized as large groups. Meeting in a home is not the same thing as disorganized religion. If you share a common creed, a common set of ethics, and common practices, that IS organized religion, no matter how small one's group.
That said, to answer your question, without organized religion, there would be no soup kitchens, no non-profit hospitals, because those kinds of charities require the organized coordination of many. That's to start with.
But there is more. People who are involved in religious communities statistically speaking have better health and well being. For reasons scientists are simply unsure of, other forms of community just don't get the same results. The relevant factors have yet to be identified.
It is also worth mentioning that evolutionary biologists are now proposing that religion is adaptive in that it helps to form cooperative groups. But for that to happen, you have to have a common religion either in the culture at large, or in your subgroup, and common religions tend to only occur in an organized fashion.
Finally, I would say I have a personal preference for religions that have educated clergy. I realize that sects such as the LDS and Friends do not have paid pastors -- they minister to one another and it seems to work fine for them. But I simply do prefer to have someone who is well educated in my religion doing the teaching. I don't think Judaism could even function without highly educated rabbis who are experts in Jewish law. I mean what if a question came up about a law, and no one knew the answer, and you got 10 different opinions?
As to would eliminating organized religion lead to less abuse of religion? I really don't know. You are basically asking me to guess without any real evidence one way or the other. Well my guess is that it would have no effect. The reason I say that is because I don't think those abuses are due to religion, organized or disorganized. I think those abuses occur because of the evil in men's hearts.
I *do* however, strongly advocate for a separation of church and state. When I look at history, when the church BECOMES the state, tyranny results. Look at Calvin's Geneva and be afraid.
