St John Houghton is remembered as the first Catholic Englishman to have been executed for refusing to take the oath prescribed by King Henry VIII’s Act of Supremacy.

Houghton was born around 1487 and is believed to have been educated at Cambridge, becoming ordained around 1511 before he entered the London Charterhouse in 1515 or 1516. By 1523, he held the position of sacristan and in 1528 that of procurator before, in 1531, he was transferred to Beauvale Priory in Nottinghamshire to serve as its prior.
But he returned to London in November that same year when he was unanimously elected Prior of the London Charterhouse. The following year was named Visitor of the English Province for the Carthusian Order.
When the King’s agents visited in April, 1534, requiring the community to take an oath as required under the 1534 Act of Succession (which excluded Katherine of Aragon’s daughter Mary in favour of Anne Boleyn’s daughter, Elizabeth), Houghton asked that the community be exempted.
Such a request was not looked upon kindly and Houghton, along with his procurator, Humphrey Middlemore, was arrested and taken to the Tower of London. Subsequently convinced that the oath was consistent with their Catholic faith by fellow clerics, the two returned to the Charterhouse in May, and there, in the presence of an armed force, the whole community eventually took the oath.
But in 1535, the community was again required to take an oath – this time recognising King Henry VIII as the Supreme Head of the Church of England as required by the 1534 Act of Supremacy. But Houghton, along with the heads of the other two English Carthusian houses – Robert Lawrence, Prior of Beauvale, and Augustine Webster, Prior of Axholme – sought an audience with Thomas Cromwell and asked for an exemption. All three were sent to the Tower.
The three men were interrogated by Cromwell on 26th April and then, a few days later, were called before a special commission and sentenced to death.
Houghton was among five clerics – along with the other two Carthusian priors as well as Bridgettine monk Richard Reynolds and John Haile, the parish priest of Isleworth – who were dragged through the streets to Tyburn on 4th May. There, Houghton – wearing his religious habit – is said to have embraced his executioner as he recited the words of the 31st Psalm before he was the first to be hanged, drawn and quartered.
Catholic tradition says that when Houghton’s body was cut open to remove his heart, he said to have prayed: “O Jesus, what wouldst thou do with my heart?”
Pieces of Houghton’s body were then displayed around London – his head was displayed above London Bridge and his arm was nailed to the gate of the Charterhouse,
Houghton was beatified on 9th December, 1886, and canonised in 25th December, 1970. He is considered one of the 40 Catholic Martyrs of England and Wales, all of whom were executed between 1535 and 1679 during the English Reformation.
