Could you please show me where the Nicene Creed is in the Bible I can"t find it in scriptures?
It is Doctrine, not Scripture. The point is, it is the centuries old canon of the Church and is a simple summation of the ESSENTIALS of the Christian faith. Theologically, doctrinally, and ecclesiologically speaking, if you do not accept the tenets of the Creeds, you are a SECT or CULT.
You can whine all day about what is or isn't specifically in Scripture. That isn't the point. It is about doctrine, tradition, and belief.Most of what Mormons believe not only isn't in Scripture, it isn't even in good science fiction.
