Are there any Christian sects that allow for the existence of other "God" claims? Are there any Christian sects that allow for the existence of other "God" claims?  That is, allow for claims that are (semi-)polytheistic in nature.  I'm excluding claims that the Trinity is polytheistic for purposes of this question.

I may have just found my answer. It turns out Mormonism allows for the existence of other "Gods" – their afterlife claims include the belief that they become "Gods".  Correct me if I'm wrong.  

Are there any other Christian sects that allow for multiple "God" claims?
I suppose some would consider Unitarian Universalists to be a Christian sect, and they certainly allow for belief in other gods.
