At one time the word hell was not in the "Apostle's" creed.<quoted text>
No date provided on the inclusion of "hell".
404 AD in the Creed of Rufinus shows the line "He descended to hell."
The Apostles Creed circa AD 700 reads in it's present form.
So, the Apostles Creed, so named, has always included the reference to Christ having descended to the dead/hell.
That means the first authors didn't receive information from on high that a hell existed.
That word "hell" was added later by other authors.
