“Or we could just say I believe God’s Word. That covers everything. The creeds leave out so much.”
Sure, we can “just say I believe God’s Word.” But nearly any member of any Christian denomination can say that (and mean it). So can Mormons, Jehovah’s Witnesses, and Christian Scientists.
Of course the Creeds don’t cover everything. They were meant to cover only those Scriptural teachings about which there had been controversy up to the particular time they were formulated. Read history.
Some claim if you don’t believe the creeds you’re damned. That’s the problem with the creeds. To some they supersede the Word itself.
