They are not considered scripture and are thus not canon. From Article VI: "And the other books (as Hierome saith) the Church doth read for example of life and instruction of manners; but yet doth it not apply them to establish any doctrine. Such are these following:
The Third Book of Esdras.
The Fourth Book of Esdras.
The Book of Tobias.
The Book of Judith.
The rest of the Book of Esther.
The Book of Wisdom.
Jesus the Son of Sirach.
Baruch the Prophet.
The Song of the Three Children.
The Story of Susanna.
Of Bel and the Dragon.
The Prayer of Manasses.
The First Book of Maccabees.
The Second Book of Maccabees.
"Any edition that only includes part of the KJV is abridged. That's the definition of abridged - parts of the original complete text are deliberately omitted."
What was omitted was never considered Scripture. So, it is not abridged scripture.
The original criteria for what was considered canonical was whether a book was read publicly in worship - hence the Articles' need to retain some ambiguity.
What was omitted was never considered Scripture.
Ah, but it was - by many. And regardless, the KJV as a complete published work included the deuterocanonicals. Any version that deliberately removes part of that work is an abridged version, by definition. This is like saying that an edition of the Federalist that leaves out the parts that were superseded by subsequent Constitutional amendments is not abridged because it has subsequently been decided by persons who are not the original editors that these portions are no longer relevant.
