There are books that are outside the protestant canon that are inspired only for the wise that seek them out. They are apocrypha which means hidden from the wise of the world.
Jesus talking to the Sadducees who asked about resurrection.
Mathew 22 29 Jesus replied, “You are in error because you do not know the Scriptures or the power of God. 30 At the resurrection people will neither marry nor be given in marriage; they will be like the angels in heaven.
God talking to the fallen angels pre flood in 1 Enoch that left heaven, came down to earth, and married women
1 Enoch 15
But you originally existed as spirits, living forever,
and not dying for all the generations of eternity;
7 therefore I did not make women among you.’
The spirits of heaven, in heaven is their dwelling;
He calls 1 Enoch scripture, and Jude says "Enoch 7th from Adam" so Jude believed what he was quoting was written before Noahs flood, and not pseudepigrapha first written 300 BC, and backdated.
Jude, and 1 Enoch
The Sadducees stuff up a story from Tobit about the woman being married then demons killing her 7 husbands each night before the marriage too. They forgot to add she married successfully the 8th time. So Jesus is calling Tobit scripture too. That was written in the 700s, and 600s BC, 1 Enoch was written 4400-4000 BC after creation 5500 BC but before Noahs flood 3300 BC. There are a lot of other texts inspired apocrypha that are not pseudepigrapha for the wise only too. My summary list of the most important ones are 1 Enoch, Life of Adam, and Eve, Assumption of Moses, 1/2 Maccabees. For the NT Gospel of Nicodemus, History of Joseph the Carpenter, Proto James.
