I am not after a punch up on this: but go and read the oath itself.
I'll give you the English, rather than the original Latin text:
The OATH.
"Ye shall swear to bear your Faith, Truth, and Obedience, alonely to the King's Majesty, and to the Heirs of his Body, according to the Limitation and Rehearsal within this Statute of Succession above specified, and not to any other within this Realm, nor foreign Authority, Prince, or Potentate; and in case any Oath be made, or hath been made, b y you, to any other Persdon or Persons, that then you to repute the same as vain and annihilate; and that to your Cunning, Wit, and uttermost of your Power, without Guile, Fraud, or other undue Means, ye shall observe, keep, maintain, and defend, this Act above specified, and all the whole Contents and Effectxs thereof, and all other Acts and Statutes made since the Beginning of this present Parliament, in Confirmation or for due Execution of the same, or of any thing therein contained; and thus ye shall do against all Manner of Persons, of what Estate, Dignity, Degree, or Condition soever they be, and in no wise do or attempt, nor to your Power suffer to be done or attempted, directly or indirectly, any Thing or Things, privily or apertly, to the Let, Hindrance, Damage, or Derogation thereof, or of any Part of the same, by any Manner of Means, or for any Manner of Pretence or Cause.
So help you God and all Saints."
It's basically saying that you can't have two masters; if you live and work and serve in England, you can't owe loyalty to foreign powers.
As far as that goes, while there might be reasons to say that's a problem, calling it "demonic" seems a far stretch.
The king clearly sets himself as supreme over all matters spiritual and ecclesiastical: in short making himself the arbiter of truth in matters of doctrine. Yet Henry 8 was never ordained and certainly not in succession, so how can he claim to know or to be arbiter of truth? I can find references in the bible to defend the popes and apostolic succession claim to that power "the power to bind and loose" given to apostolic successors jointly, but also Peter alone.
You can't sidestep the long tradition of the godly Prince, and of the authority of various emperors etc. exercised in the church, though. Remember that this is a time where there is no such thing as separation of church and state. Henry is reasserting an older position - generally somewhat eroded by his time - of the role of the civil ruler in church affairs. You might disagree with him, but if we look back to things like the investiture controversy, or indeed the role Constantine played in church governance, we can see that this tension is much older and more complicated than just Henry claiming to be "arbiter of truth."
i think the bible anglicans use contain the apocrypha books
We do generally read the deuterocanon. However, from our Articles of Religion: "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."
