I found it really helpful to understand the history behind various religions ( )

A quick look at the major religions of the world, how they evolved and what they have in common. Also contains information on how Christianity adopted pagan beliefs as their own, and therefore contributed to following traditions of men.

This has been a fine look into other religions outside Christianity. And, yet, it also traced the deviation (apostasy) from the Christianity that the founder, Christ, had originally established. Like a history detective this publications gets to roots of the religions of the world. As time goes by perhaps an update will follow as new discoveries are made in archeology and other studies of humanity in general. ( )
