Oliver Plunkett
Irish archbishop, martyr and saint; (1629-1681)
Feast: 1 July (not on the universal Roman calendar; kept in the Roman Martyrology or local calendars)
Who they were
Oliver Plunkett was born at Loughcrew, Co. Meath, on 1 November 1625. In 1647 he was sent to Rome, where he stayed for twenty-two years: he studied at the Irish College, was ordained a priest in 1654, and taught at the College of Propaganda Fide.
Appointed Archbishop of Armagh and Primate of All Ireland in 1669, he spent twelve years preaching, teaching the young, building up Catholic schools and caring for his clergy. Arrested in Dublin in December 1679 and falsely accused of plotting a French invasion, he was tried for high treason at Westminster Hall in London and hanged, drawn and quartered at Tyburn on 1 July 1681. On the scaffold he forgave everyone who had a hand in his death. His head is kept in St Peter's Church, Drogheda.
The miracles
Giovanna Martiriggiano — Naples, Italy — 1958
An Italian mother was at the point of death. Through the night her husband prayed beside her with Sister Cabrini Quigley of the Medical Missionaries of Mary, asking Blessed Oliver's intercession. Against all expectation she revived and recovered fully without further treatment. Her surname, fittingly, comes from the Italian word for martyr.
As a martyr, Oliver Plunkett was beatified without a miracle: the Church holds that dying for the faith is itself the proof. The miracle above was the one required for his canonisation, which made him the first new Irish saint in almost seven hundred years.
Why that counted as sanctity
Beatification followed on 23 May 1920 by Benedict XV. The case of Giovanna Martiriggiano was examined by the Church's doctors and theologians and approved as a miracle, opening the way to canonisation. Canonisation followed on 12 October 1975 by Paul VI.
