We are saved not by our correct confession -- as important as that is -- but by our trust in the One in Whom we confess.
The importance of the Creed is that the Creed tells us the nature of the One we trust. And conversely, helps us not to trust in false gods.
A side issue to that is to avoid messing with the Creed. It's a constant temptation to imagine that people are bored with the Creed, that we've heard it enough, that we know everything there is to know.
We don't. But that's not the point. The Creed not only tells us about the nature of the One we are to trust, but about the nature of the world, the unity and diversity of reality, the source of creedal knowledge, the end of time, and eternity.
