How does the Gospel of Mark support statements in the Nicene Creed?

None. Nicene Creed was composed by a Saulinist committee. Mark did not exist.

It and them do not. Jesus (Yahushuwah) explained the Almighty Father to be the only true God. And by the way, God actually means Almighty.

Now how many Almightys can there be?

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
