Blake Bites: Why does William Blake say that All Religions are One?

In his first work in illuminated printing, Blake writes provocatively that "all religions are one". While this has been taken by some to mean that Blake believes all religions are the same, in fact it refers to his idea that all religions find their source in human imagination.

"Till a system was formed, which some took advantage of & enslav'd the vulgar by attempting to realize or abstract the mental deities from their objects; thus began Priesthood. Choosing forms of worship from poetic tales. And at length they pronounced that the gods had orderd such things."
-William Blake
