The Vikings often accepted the Christian God too along with their Gods.

The God Odin has parallels with the Christ crucifixion who was hanged on a tree and resurrected a few days later.

So those who think they are both a contradiction no they are not.

And for the record Norse pagans don't worship Gods.. at all.

They do not see it that way at all. They just believe in many co-creators.

But they don't pray to them all!!!! Nor ask for favours.
