Yeah, like how opiates today still have very valid medical uses, but their application has become so widespread that they've left the realm of medical tools (for many people) and entered the realm of escapism.

When people aren't turning to religion because of their total fear of destruction and destitution by capitalism, and the churches themselves begin to take on a more community organized and driven structure, you'll see the "true" form of religion emerge and over time the need for that religion will fade as the needs that were sated by religion becomes sated by the community as a whole.

Or at least the religion begins to take on the form of the socialized society that it exists in as opposed to impressing it's own hierarchical structure on the society that seems it out.
