We have, in The West, experienced a couple of centuries of high level critique and rejection of Christianity - perhaps most famously/ influentially by Nietzsche, who blamed in-practice Christianity for that attitude of passivity, guilt, self-hatred, and covert suicide that now dominates The West (even though it is several generations since Christianity was excluded from all significant public discourse in The West).
The implication is that either we go back to pre-modern 'traditional' Christianity - along with everything that might entail such as monarchy, top-down rule by the church, agrarian societies etc.
Or else we re-make the philosophy of Christianity - which entails making a distinction between actual Christianity and all traditional attempts to describe, explain, instantiate and implement it. It means re-examining the assumptions of that Greek-Roman philosophy within-which traditional Christianity is explained. It means re-examining the assumption that Christianity be church-led and church-controlled. Re-examining the usually historical understanding of Christianity; the several assumptions underling the assertion of of the primacy of scripture; and very idea of tradition itself...
In other words; the choices are traditional Christianity (in some version or another) and re-making the medieval world; or else Romantic Christianity (in one form or another) and using this as the basis of an unknown and unknowable future.
But if we conclude that the traditional path is both (overall) undesirable and (actually) impossible* - then there is only one choice: Romantic Christianity.
*I shall not attempt to persuade anybody of this; but I tried for several years to think through the implications - honestly - and found the project to be literally impossible; as well as harmful to embark upon. This despite my being perfectly clear that the Medieval Traditional world was objectively better - more God-aligned, more good, more motivated to be in accord with divine creation than is the world in 2021. Much better. Until you understand how these two convictions (better - and also bad/ impossible) are simultaneously possible, then you do not understand the point I am making (whether or not you agree with it is another matter!)
