Having said that, the spiritual motivation must be positive. Getting back to the land to get away from Clownworld will not suffice. More is needed.
What the “more” is depends on the individual, but I suspect it will have to involve confirming or challenging one’s deepest metaphysical assumptions.
Those holding traditional/conventional Christian metaphysical assumptions will inevitably work to reconstruct some earlier Christian feudal/agrarian society centered around a church. All I can say to Christians who are thus motivated is this: Good luck with that! Drop me a postcard in a few years to let me know how it is going.
Those holding more unconventional/adventurous/creative Christian metaphysical assumptions will – hopefully – find themselves in an undiscovered country where their deepest metaphysical assumptions will be confirmed – provided their motivations to confirm such assumptions remain sincere.
Of course, confirming such assumptions does not require self-sufficiency or getting back to the land. The undiscovered country is accessible everywhere, including mundane subdivisions, dreary apartment blocks, or elegant gated community manors – provided the motivations remain sincere.
