When a man takes an oath, Meg, he's holding his own self in his own hands. Like water. And if he opens his fingers then — he needn't hope to find him… - Robert Bolt

Roper: So now you’d give the Devil benefit of law?
More: Yes. What would you do? Cut a great road through the law to get after the Devil?
Roper: I’d cut down every law in England to do that!
More: Oh? And, when the last law was down, and the Devil turned round on you – where would you hide, Roper, the laws all being flat? This country’s planted thick with laws from coast to coast – man’s laws, not God’s – and, if you cut them down – and you’re just the man to do it – d’you really think you could stand upright in the winds that would blow then? Yes, I’d give the Devil benefit of law, for my own safety’s sake.

More: You want me to swear to the Act of Succession?
Margaret: "God more regards the thoughts of the heart than the words of the mouth." Or so you've always told me.
More: Yes.
Margaret: Then say the words of the oath and in your heart think otherwise.
More: What is an oath then but words we say to God?

Norfolk: I'm not a scholar, as Master Cromwell never tires of pointing out, and frankly I don't know whether the marriage was lawful or not. But damn it, Thomas, look at those names... You know those men! Can't you do what I did, and come with us for friendship?
More: And when we stand before God, and you are sent to Paradise for doing according to your conscience, and I am damned for not doing according to mine, will you come with me, for friendship?
Cranmer: So those of us whose names are there are damned, Sir Thomas?
More: I don't know, Your Grace. I have no window to look into another man's conscience. I condemn no one.
Cranmer: Then the matter is capable of question?
More: Certainly.
Cranmer: But that you owe obedience to your King is not capable of question. So weigh a doubt against a certainty — and sign.
More: Some men think the Earth is round, others think it flat; it is a matter capable of question. But if it is flat, will the King's command make it round? And if it is round, will the King's command flatten it? No, I will not sign.
