Renting is a good choice for people who can’t immediately absorb big expenses. If your furnace quits, it can be really nice to phone the landlord and ask them to fix it. Homeowners have to have ready access to cash, and not everyone is in that situation - especially when they are starting out.
I am a lifelong atheist. I attend a very progressive christian church where I am open about my lack of belief. They seem to accept me, including the minister. I don’t try to convert them and they don’t try to convert me. I started going because I was lonely and I wanted some opportunities to do good. Their whole theology is about helping people and trying to change the world for the better. The two major precepts are “God is love” and “Jesus has no hands but yours.” They don’t talk about sin or redemption. We have a huge rainbow sign that says “All are welcome,” and we actually mean it. The minister talks about Jesus as a teacher, not as a saviour. We raise money and food for the local food bank, and provide community outreach to people, many of whom have disabilities. We sing. We eat cookies and drink absurd amounts of coffee. I suddenly have so many sweet old lady friends, and even a handful of friends my own age.
