The Cult of Moloch drives out all others.
The established Modern Cosmopolitan Cult is the Cult of No Cults. It is the Cult of Nothing. Only a Cult of Nothing could risk much room within its temenos for other cults – the Christian, the pagan, the Mohammedan, and so forth. For, all those other cults have positive principals, each of whom with his worshippers would be at odds with the others, contesting for dominance over the hearts and acts of the cosmopolitans, until one of them achieved the victory and established his own cult. Were any of them established, they would make no such room for their competitors within their own precincts. So all such positive cults will tend to engender a state of affairs in which they may be established and their competitors driven out.
