Why is the Creed included in morning prayers? Isn't it rather just a statement of belief? It is a statement of belief, of course...but when we speak it in the presence of God who has made us His own children in Baptism and has made our bodies into His temple, then it is our prayer as well. We are simply saying back to Him in summary what He has said to us; and our confession of what He has said to us is a plea that He keep us in this faith - since it is not of our own invention but of His revealing.
