The religions of the Occident were always less sophisticated on the surface than religions like buddhism. But Xtianity had a subtle core that drove the religion through its imperfect manifestations. The issues of Xtianity are somewhat hard to fathom: we spent two thousand years in Xtianity and will spend the next two thousand trying to figure it out. So the latter will be one aspect of the future.
As you note, it is easy to solve all these problems, but they won’t appeal to many.
Here my core objective is to see how a core Xtianity could assist in the transition to a new form of society. Historical materialism wasn’t up to the task, so we have to start over.
We too easily forget in the context of modern non-believers that even after we criticize religions like Xtianity it remains the case that they have a spiritual dimension. And that is complex.
One observation is that for all the confusions over theology the elusive spiritual guides didn’t care a jot, mostly: the secret behind Xtianity is that it worked just as well for confused persons.
In any case we can see sometimes the two levels, like my discussion of the Trinity and Samkhya.
If anyone with the skills to do so were to study Xtianity at close range, the muddle zone of the ‘born again’ phenomenon clearly shows a statistical reality of help asked for and help received. And Xtian populations didn’t have to worry about dark side comedians of the Aleister Crowley type: witchcraft and black magic were protected against, up to a point. We are beginning to see the resurgence of all these devils in the woodwork and people now don’t even consider it a problem to use magic against helpless people.
As the saying goes, you’ll be sorry. The text of the ‘three little pigs’ is relevant here.
