The primitive church read the book of Enoch; the people of Israel always read it, and, in fact, it is mentioned in the scriptures.
When Athanasius constituted the Bible, he left Enoch out, but that does not mean it is not a book of God or that it would not be mentioned in the Bible.
Enoch was translated to heaven to be a witness against a perverse generation. The holiness of Enoch stands before the divine court to testify against the wickedness of the world.
The word “witness” is a title given to someone in court to judge or defend someone. The holiness of Noah condemned the world.
The heroes of faith are witnesses; their level of faith contributed to a level of holiness, and this level of holiness, when they are taken to heaven, makes them witnesses.
