paganism
UU well described in Phillipians:
17 Brothers and sisters,* join in imitating me, and observe those who live according to the example you have in us. 18For many live as enemies of the cross of Christ; I have often told you of them, and now I tell you even with tears. 19Their end is destruction; their god is the belly; and their glory is in their shame; their minds are set on earthly things. 20But our citizenship* is in heaven, and it is from there that we are expecting a Saviour, the Lord Jesus Christ. 21He will transform the body of our humiliation* so that it may be conformed to the body of his glory,* by the power that also enables him to make all things subject to himself.
paganism
U-Us do not refer to themselves as Christian, (or maybe some do) at least according to their somewhat vague FAQ.
