Today in 1551 Edward VI’s Lord Chancellor Richard Rich visited Edward’s Half sister Mary to tell her she needed to stop celebrating the Catholic Mass. This was a constant thorn in the side of Edward. Mary was his half sister - the daughter of Henry VIII and Catherine of Aragon, and she would remain staunchly Catholic. This was a problem for Edward, who was raised by Protestant tutors, and was trying to rework the country into a Protestant one. It didn’t work for him to have his sister openly flaunting the laws of the country, Princess or not.
