Satan even knows that the statements made in the Nicene Creed and the Apostles Creed are correct. I can imagine he says yea, I believe that too.
Yep. As long as the GOSPEL is left out, it doesn’t matter what else is included. Satan can read them all and say “yes, correct, I know that, I believe that” and be on his way. It’s the Gospel that makes a creed worth anything.
