Martyrs of England Crowned by Christ.
"Almighty God, who in our country raised up martyrs from every walk of life to vindicate the authority of your Church in teaching and worship, grant through their intercession, we pray, that all our people may be gathered one again to celebrate the same sacraments under the one Shepherd, Jesus Christ your Son. Amen." – Collect for the Feast of the English Martyrs. Stained glass roundel by Margaret Rope from the Martyrs Crypt in Tyburn Convent, London.
