 Carew took pains during this period to distance himself from the Roman Catholic upbringing he had in the household of the Marquess of Exeter and openly supported Protestant groups who had fled to Calais after persecution elsewhere in Europe.His stance on this issue brought admiration from several contemporaries, including John Foxe.Carew was with the deputation which met Anne of Cleves in December 1539 and the following year he was briefly arrested and questioned in relation to a plan to hand Rysbank over to the French, a plot in which Lisle was implicated but Carew apparently was not.
