Ndigila,
Hope you are aware of Mythra. Would you compare and contrast the religious traditions, worship methods, philosophies, and general doctrines of this ancient religion with the practices of Christian Church at around 150AD onwards?
bible history mysteries oddities and fascinating facts has some nice materials on origin of some philosophies that were adopted by the church.
I'll bring some specific objects of belief in Mythra and ask why such beliefs warranted borrowing by the church.
