Unlike the Mennonites, Orthodox Judaism is not a good example of an undepraved community. Judaism has moral issues. But what Orthodox Judaism is a great example of is resisting modern culture. In fact I don't think any other community resists modern culture as effectively as Orthodox Judaism does.
Unlike with the Mennonites, I don't particularly recommend visiting an orthodox synagogue. You can if you want, but they will not be welcoming and they will not be honest with you, that is if you aren't racially jewish. Since I am racially jewish, I benefitted from attending orthodox synagogue for a year, attending weekly classes on judaism, and paying for weekly private classes with the rabbi. Based on this, I can recommend resources that I think are authentic.
To understand how Judaism is so effective at resisting modern culture, you have to realize that the survival of Judaism depended on resisting assimilation, and that this began with the Babylonian conquest of Judah 2600 years ago. Since that time Judaism has existed in exile by resisting assimilation.
Now we can consider what we can learn from this example. The points most worth considering are those things that are common to both Orthodox Judaism and the Mennonites. So I will enumerate these. First, electronic entertainment is seriously restricted in both groups, particularly for children. Both groups organize schools for their children and never send their children to public school. Both groups have strict rules of modesty. Both groups separate men and women in religious service. Both groups have strict rules for dating. I think that any successful undepraved community would follow these things.
I will also discuss what they have in common in terms of religious organization, but how this would apply to Undepraved isn't obvious and I will discuss these issues separately in other posts. Both Orthodox Judaism and the Mennonites are organized into groups of churches/synagogues that share rules and religious detail. There is no central authority over these groups. Both religions freely allow innovation in religion which allows them to adapt to new threats like electronic entertainment. Innovation in religion is a complicated topic that I will cover in another post. Both groups have strict rules for membership which, if violated, can result in expulsion.
There are also significant differences between Orthodox Judaism and the Mennonites. In particular, how they deal with the outside world. The Mennonites are required to basically love everyone. They are honest in business and are non-violent. With such high standards of dealing with people, they can't really survive in populated areas where the depraved population would take advantage of them and destroy them. In contrast, Orthodox Judaism views non-jews as basically animals to whom no moral obligation exists. This allows Orthodox Judaism to thrive in populated areas. But this approach violates the morals of any moral religion, so it won't work for Undepraved. I think the solution lies in between these two approaches, and I will discuss this in another post.
I hope you have time to watch the three videos I linked to above. Then you can post your thoughts to this thread.
