 In 1609 he published "Tortura Torti", a learned work which grew out of the Gunpowder Plot controversy and was written in answer to Bellarmine's "Matthaeus Tortus", which attacked James I's book on the oath of allegiance.After moving to Ely (his election to that See was confirmed on 22 September), he again controverted Bellarmine in the "Responsio ad Apologiam".In 1617 he accompanied James I to Scotland with a view to persuading the Scots that Episcopacy was preferable to Presbyterianism.
