On the morning of 19 May 1935 in St. Peter's Basilica, this Solemn Proclamation was made by Pope Pius XI:
"In honour of the Undivided Trinity, for the exaltation of the Catholic Faith and the increase of the Christian religion, by the authority of Our Lord Jesus Christ, of the Holy Apostles Peter and Paul, and our own, after mature deliberation and imploring the divine assistance, by the advice of our Venerable Brethen the Cardinals of the Holy Roman Church, the Patriarchs, Archbishops and Bishops present in the city, We decree and define as Saints, and inscribe in the Catalogue of the Saints, Blessed John Fisher and Thomas More, and that their memory shall be celebrated in the Universal Church on the anniversaries of their heavenly birth."
Although St. Thomas More was martyred on 1 July, two weeks after St. John Fisher, their respective feast days have been joined together and are celebrated on 22 June.
O God, who didst raise up amongst the English people thy blessed Martyrs John and Thomas to be defenders of the faith and to witness to the primacy of the Roman Church: grant by their merits and prayers; that in the profession of one faith we may all be made one in Christ, and in him continue to be at one with one another; through the same Jesus Christ thy Son our Lord, who liveth and reigneth with thee, in the unity of the Holy Spirit, ever one God, world without end. Amen.
