Mmm, not essentially.
My God (The Christian God) is pretty much the same God in a lot of faiths.
(Judaism, Muslim, Catholicism etc)
And I've brushed up a fair bit on the others, And decided that they were not for me.
However, the other religions who have different God/s I have not even begun to look at them, So I suppose it's a lack of education about them that keeps me from them.
But no, I don't dismiss other Gods, In fact, I prefer to think we all worship the same God, Just in different ways and with different names.
(This is a personal thought, Not really shared with other religions/Christians)
