If God is gender-less, then it should be that both male and female could be assigned, particularly as creator female, would be more appropriate.
Well its not without its proof texts I.e. Deut. 32:18 “You forget the rock who begot you, unmindful of the God who gave birth to you”
Anyway, to get back to the OP, there are big doctrinal differences between mainstream Christian groups but many similarities, it's when we include the spin off Christian groups like the JWs that this exercise becomes difficult, but this is largely because many Christian cults intentionally reject mainstream Christian doctrine in order to separate themselves. It shouldn't be a surprise to find few similarities between groups that are trying to avoid similarities.
