Here are a few simple resources for someone asking “What’s out there already in the way of intentional Christian communal living?”
A network of catholic/anabaptist communities. Jonathan Wilson Hartgrove, Shane Claiborne
My own church’s membership covenant which my wife and I signed
Reba Place Fellowship, over fifty and still very influential
I’m intentionally keeping this list small. There are many more. If you want to visit a community don’t just show up. Do your homework. Arrange a formal visit. Be prepared to ask good questions and talk about yourself. That would make it a good experience.
