Many traditions have copied parts of Christianity. When Constantine mandated Christianity one consequence was likely forcing these beliefs underground and a way to do that is to conform them. So, hard to say which occurs first. Greek and roman hermeneutics seem relativistic with respect to current events. Christian doctrines have been consistent throughout.
Good start though IMO he missed some rather important factors such as technological platforms and the extent to which intentional coordination occurs (ie bilderberg). He alludes to the impact of platform censorship but does not focus on sociotechnical as a major force. Most the talks at Davos etc focus on this more than $.
I also personally believe there's major spiritual forces at play too. Though, this is a whole separate discussion.
