Cromwell: The King's a man of conscience and he wants either Sir Thomas More to bless his marriage or Sir Thomas More destroyed. Rich: They seem odd … - Robert Bolt

Cromwell: You brought yourself to where you are now.
More: Yes. Still, in another sense, I was brought.

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.

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 himself again.
