John Mason
Layman, martyr of the persecution in England
Who they were
The Roman Martyrology remembers him at London among the martyrs who suffered at Tyburn in the same year as Polydore Plasden and Eustace White, some for having entered England as priests and others for having helped them; the Acts of the Apostolic See list him among the one hundred and thirty-six English martyrs as a layman hanged at Tyburn on 10 December 1591. He was beatified by Pius XI on 15 December 1929.
The miracles
As a martyr he was raised to the altars without a miracle.
Why that counted as sanctity
He was put to death at Tyburn for helping priests.
