The first part of Sir Thomas' letter asks Margaret to pass along his love and blessing to the rest of the family, so I will only include the second half of it - where he addresses Margaret herself and says his final farewell.
"I cumber you, good Margaret, much, but I would be sorry if it should be any longer than to-morrow, for it is St. Thomas's even, and the utas of St. Peter; and therefore, to-morrow long I to go to God. It were a day very meet and convenient for me.
I can't imagine being poor Margaret and receiving this last letter from my father - especially after all I have read about them, and learning about how close they really were. This was an extraordinarily difficult time for the More family, though Sir Thomas seemed to be content with death. He knew he would be dying as a Catholic martyr, right on the heels of his close friend and fellow staunch Catholic, Bishop Fisher, who's head was at this time mounted on a spike on Tower Bridge. What a bloody and terrifying time. This letter certainly makes me feel for the people and families that were affected by Henry VIII's cruel punishments, but it also shows the bravery and overwhelming faith that lived on in the soon-to-be-sainted Thomas More.
