The Apostle's Creed is like a map. It may be less real than the Bible, yet it does not diminish its usefulness anymore than the usefulness of a map is diminished by the reality of the terrain it depicts. On its own, the Apostle's Creed has no authority in and of itself. However the truths it declares are rooted and grounded in the reality of the Bible as the Spirit-inspired, Spirit-breathed Word of God. The Apostle's Creed points you to the Bible because the truths it confesses come from the Bible.
