Freud and Religion

I think it would be interesting to see how Freud's views on religion would play out with a focus on a non-Christian religion.  A lot of his argument focuses on God as a benevolent paternal father figure and the way that that's expressing the way that children revere their parents when their young.  What about Old Testament portrayals of God, or in religions where there is no benevolent father figure?  Or is there always a patriarch?  After all, there's Zeus in the Greek pantheon, but (outside of Disney) I wouldn't necessarily refer to him as a benevolent father figure...
