In the series 'The Tudors' which I know is pretty dire but I confess I have seen

when Thomas More resigns the Chancellorship he promises Henry that he will not speak about Henry's Great Matter. I think that is fact? However he also promises that he will not write anything against it either. I know that he did write, a lot, and as I can't imagine him as the king's good servant breaking a promise, is that part true? Did he in fact promise not to write against it?
