I don't agree in some points with you, Roman Empire lasted in one form or the other, precisely due to religions. In the West due to Catholicism and it created the base for the western development . In the East it was the Ottoman Empire whose rulers till 1699 were titled Roman Emperors and they were de facto and de jure . Holy Roman emperors were not due to relinquishing those rights 478 ( by the pope and Augustul Romul).
The real destroyer of the natural order was Protestantism, it created chimera concept like egatelorism. In other words, it was esoteric Cult, esoteric cults are diametrically opposite of the set and codified belief. In there liyes a rabbit hole. All history of those ideas have suspicious origins, motivation etc . It is has always been closely associated with the " progres" or ' reason " and leads to the various types of superstitions and Atheism. Open faze lasts 230 years and we have come to the full circle. Now the people of " reason, egality, fraternity and liberty " stop believing that such thing as women is a tangible fact and they persecute " fanatics " who believe otherwise. Considering the nature of the things , it is not surprising. Powers to be always need lumpen proletariat.
Oh by the way The Emperor Julius Apostate , the last pagan Roman Emperor was a devout pagan in the classical sense .
Also one of the problems is so called modern Atheism, the old one knew if there is no God there is no much point in this world. But the new one , though admitting ,that the only true purposes are survival and multiplication gives itself pseudo moral and religious qualities. In other words, they want to be gods
Oh , one thing confuses me , why an amoeba which has the perfect survival and reproductional skill decided to evolve to something infinity more unsure like us?!
