Too much doctrinaire mish mash for me.
If you say so, but where is the "doctrinaire mishmash"? Or is simple comparison now "mishmash"?
If early Christian communities, where the sharing of, and pareclling-out, of common resources, is not socialism, then what is? It should not matter that socialism was not, at the time, a (half-)thought-out political doctrine, nor that the underlying motivation was religious rather than political or economic.
If the notion was presented to you free of the religious angle, would you recognize it as socialism in action?
