Michael Treharne Davies (13 March 1936 – 25 September 2004^[1]) was a British teacher andtraditionalist Catholic writer of many books about the Catholic Church following theSecond Vatican Council. From 1992 to 2004 he was the president of the international traditionalist Catholic organisationFoederatio Internationalis Una Voce and was responsible for the unification ofUna Voce America.^[2]

Davies was born to Cyril and Annie (née Garnworthy) Davies. His father, aWelshman, was aBaptist, and his mother, who wasEnglish, was anAnglican. Davies was brought up inYeovil, Somerset,^[3] but proud of hisWelsh descent. He served as a regular soldier in theSomerset Light Infantry during theMalayan Emergency, theSuez Crisis, and theEOKA campaign inCyprus.^[4]

Davies was aBaptist who converted to Catholicism while still a student in the 1950s.^[5][6] While initially a supporter of theSecond Vatican Council,^[7] Davies became critical of the liturgical changes that followed in its wake, which he argued were a result of distortions and misreadings of the Council's mandates forliturgical reform.^[8]Davies later supported the French ArchbishopMarcel Lefebvre, founder of theSociety of St. Pius X (SSPX), writing a three-volume series titledApologia Pro Marcel Lefebvre in which he defended Lefebvre against accusations of disobedience and schism for refusing to celebrate theMass of Paul VI.^[9] Although Davies opposed Lefebvre'scanonically-illicit consecration of four SSPX bishops in 1988 against the wishes ofPope John Paul II,^{[citation needed]} he continued to support Lefebvre's defence of theTridentine Mass and traditional Church teachings publicly.

William D. Dinges, Professor of Religion and Culture atThe Catholic University of America, described Davies as "[i]nternationally, one of the most prolific traditionalist apologists".^[10]

Davies was a critic of thealleged apparitions of theBlessed Virgin atMedjugorje, which he believed to be false.^[11] His unfinished book on the subject,Medjugorje: The First Twenty-One Years, was finally published in 2023 by Arouca Press; it includes a reminiscence from his son Adrian.

Davies died on 25 September 2004, aged 68, following a battle with cancer and was buried in the churchyard ofSt. Mary's, Chislehurst, Kent. He was survived by his wife, Marija, one daughter and two sons,^[12] one of whom is the barrister Adrian Davies.
