Why did Hugh Latimer say Play the man Master Ridley we shall this day light such a candle by God's grace in England as I trust shall never be put out?

Hugh Latimer was bishop to both the Worchester (before the reformation) as well as a bishop of the Church of England and Chaplain to King Edward VI. Latimer was burned at the stake for his beliefs and teachings under the reign of Mary I and Nicholas Ridley was his executioner. He is believed to have made this quote prior to his death.
