Once he Entered in Portugal he used the name “Cornelio de San Patricio”
After First Vows Sent as Prefect of Studies to Irish College Lisbon
1626 Sent to the Azores as Professor of Moral Theology at San Miguel, Angra, quickly establishing a high reputation throughout Portugal. During the 1630 earthquake at San Miguel, he showed resourcefulness and courage in bringing help and consolation to those rendered homeless by the disaster.
1633-1639 Sent to Évora to teach Moral Theology. He had graduated MA - but unclear if this was in Spain or Portugal.
1639-1642 Sent to Irish College Lisbon to teach Moral Theology
1642 Operarius at the Professed House in Lisbon, where he died 28 February 1656
His celebrated book “Disputatio Apologetica et Manifestativa de Iure Regni Hiberniae pro Catholicia Hibernis adversus Haereticos Anglos ” possibly makes him considered as the first Irish “separatist” of modern times. This book was circulated in Lisbon, but bears the name of a non existent publisher in Frankfurt. The book was denounced by João IV of Portugal, an ally of England. O’Mahony proposed that the solution to Irelands problems might be the election of a King of old Irish stock, and also urged war to the death of all English Protestants in the country. The thesis of the book was used by the Confederation of Kilkenny to attack the position of Eoin Ruadh. It was a century and a half later, with Wolfe Tone and the United Irishmen before this thesis was proposed again. O’Mahony’s book was reissued in Dublin in 1826 by those who wished to raise anger against the Catholic Church and the Emancipation movement.

O'Mahony, Conor
by Tadhg Ó hAnnracháin
O'Mahony, Conor (1594–1656), Jesuit academic and author, was a native of Muskerry, west Co. Cork. Little of his early life is known until his entrance into the Irish College at Seville, probably in 1614, where he studied philosophy and theology for three and four years respectively, ultimately graduating as master of arts and doctor of divinity. He was admitted to minor orders on 7 June 1618 and was ordained a priest on 21 December 1619. The following year he was almost expelled from the college for unspecified misdemeanours. In 1621 he entered the novitiate of the Society of Jesus in Lisbon and took the name ‘Cornelius a Sancto Patricio’. In and around 1626 he went to the college of San Miguel in the Azores, where he was to spend seven years as professor of moral theology. He is also recorded as having performed great service to the victims of an earthquake and eruption at Ponta Delgada in 1630. O'Mahony held the chair of moral theology at the university of Evora (1633–5), and in 1636, the year of his final profession as a Jesuit, was transferred to Lisbon, where he became professor of dogmatic theology for five years.
The experience of living in Portugal during the Braganza revolt against the Spanish Habsburgs and, almost certainly, personal acquaintance with several of the Jesuit scholars who provided intellectual justification for the Braganza position, were of critical importance in conditioning his own reaction to rebellion in Ireland and the formation of the Confederate Catholic Association in 1642. In 1645 he published in Lisbon the text on which his historical reputation rests, the Disputatio apologetica de iure regni Hiberniae pro catholicis Hibernis adversus haereticos Anglos, a two-part work consisting of a ‘disputatio’ and an ‘exhortatio’.
O'Mahony's purpose was to demonstrate that the ‘Hiberni’, a generic term which he used to denote all the catholics of the island, had the right to reject the authority of the monarchs of England over Ireland. In the ‘disputatio’ he first rehearsed a series of arguments which might be advanced to legitimise English authority, and then proceeded to attack them. His arguments were intensely legalistic and the historical underpinning was somewhat weak. The second part of the ‘disputatio’ was relatively stronger. It adapted the work of Bellarmine, Suarez, and Molina to build a case that, even if English monarchs had once legitimately ruled over Ireland, the Irish retained the right to eliminate their authority because of the lapse into heresy of Charles I and his two predecessors. The ‘exhortatio’ that followed, drawing heavily on biblical example, urged the Irish people to choose a new catholic and native monarch and to eliminate all the remaining heretics in the island.
Although emotional resonances with O'Mahony's book can be detected in some manuscript material produced after the rebellion of 1641, it received almost no public support among the audience for which it was avowedly written, the Confederate Catholics of Ireland. The book ran counter to the dominant current in Irish catholic political ideology, which stressed the legitimacy of Stuart rule. In 1645, the year of its publication, even the clerical convocation, the most militant group within the association, dismissed out of hand the idea that Charles was not the confederates’ legitimate king. Radical catholics within the association opted to refer to the confederate oath of association to justify their objectives, rather than to O'Mahony's dangerously divisive argumentation. Moreover, the frank approbation in the ‘exhortatio’ for the killing of 150,000 protestants since the initial rebellion was particularly unwelcome to the great mass of the Confederate Catholic leadership, who wished to avoid any link to the alleged massacres of 1641. The confederate executive ordered that copies of the book should be burned by the common hangman, and evidence has survived that the city of Galway independently expressed its abhorrence for the book and its author. Peter Walsh (qv) is also said to have preached nine sermons against the book in Kilkenny.
Although it attracted little support in Ireland, O'Mahony's text did contribute to the divisions that racked the confederate association in the later years of the decade. It was feared in some quarters that his book was intended to provide the theoretical underpinning to an attempt by Owen Roe O'Neill (qv) to wrest the sovereignty of Ireland from the Stuart monarchy. O'Mahony's work also increased the difficulties of the papal nuncio Rinuccini (qv), who was suspected of plotting to establish papal suzerainty over Ireland and who was accused in Rome by Sir Kenelm Digby of tolerating the Disputatio apologetica. Rinuccini may also have refused to hand John Bane, a parish priest in Athlone, over to secular justice after he was discovered with a copy of the book in his possession. For his part the papal nuncio related some of the hysteria evoked by the text to the fears of secular landowners that O'Mahony's arguments might be used to delegitimise their continued possession of former monastic property. The divisive effect of the book seems to have been heightened by the general lack of knowledge concerning the true identity of its author. This may well have been a conscious decision on the part of O'Mahony, as the title page of the book gave a bogus place of publication. Alternatively, the reference to Frankfurt as the place of publication in the title imprint may have been a device to escape the attentions of the Portuguese censor.
As it transpired, the efforts of the English ambassador, Sir Henry Compton, resulted in two separate condemnations of the text in Portugal on 6 April and 5 December 1647, although no action seems to have been taken against O'Mahony. In the post-confederate period the Irish Jesuit did reveal himself as the text's author to Patrick Plunkett (qv), bishop of Ardagh. Having been in good health, he died suddenly 28 February 1656 at the Jesuit House in Lisbon.
After his decease, copies of the Disputatio were never common: the authors of the Commentarius Rinuccinianus, for instance, had never seen the text but it did enter into later Irish protestant mythology. In 1689 Richard Cox (qv) described it as ‘a most treasonable and scandalous book’ and observed that it was not publicly condemned by the congregation of catholic clergy in Dublin in 1666. A small number of copies of the work were reprinted, apparently in 1826, probably as part of the campaign against catholic emancipation.

Father Cornelius O’Mahony SJ 1594-1656
Constantine O’Mahony was born at Muskerry County Cork and became a Jesuit in 1621. When his formation was complete, he professed Philosophy at Lisbon.
In 1645 he published his “Disputatio Apologetica et Manifestiva de Iure Regni Hiberniae pro Catolicis Hibernis Adversus Hereticos Angles”. It was published under the pen name Constantine Marillus. The thesis of the book was that the supreme authority of a nation lies in the representatives of the people, the teaching of St Robert Bellarmine and Suarez. The book gave great offence to the Supreme Council at Kilkenny, and had the distinction of being publicly burnt in the market place of the same town. It was reprinted in Dublin in 1827, 100 copies. The book is singled out for special mention and attack by Hector McPherson in his book called “England’s Fight with the Papacy” in the chapter entitled “The Jesuits in History”. McPherson says that O’Mahony was regarded as “a great light in moral Theology in Lisbon, according to Roman Catholic circles”. Harris in his “Writers of Ireland (p121) describes O’Mahony as “a Jesuit of most virulent temper”. However, we are warned by Oliver and his colleagues, that Harris’ opinion of the author and his work must be received with caution – “much is heavily grounded on hearsay evidence”.
Fr O’Mahony was often called Cornelius a Santo Patricio. He was alive in 1650 at Lisbon, though very old
◆ George Oliver Towards Illustrating the Biography of the Scotch, English and Irish Members SJ
MAHONY, CONSTANTINE, born at Muskerry, in the County of Cork,and often called “Cornelius a Sancto Patritio” Harris, p. 121, Book I, of the writers of Ireland, describes him as “a Jesuit of a most virulent temper”, and says that he published a book under the feigned name of Constantine Marullus, entitled, “Disputatio Apologetica et Manifestiva de Jure Regni Hiberniae pro Catolicis Hibernis adversus Haereticos Anglos”, 4to. Frankfort, 1645. Harris’s character of the work and of its author must be read with caution : much is evidently grounded on the hearsay of enemies. One assertion, that Pope Gregory XIII, had granted to Owen Rowe O’Neil a Bull in 1642, “whereby all the actors in the bloody massacre of the foregoing year are blessed”, is the compound of the vilest absurdity and most atrocious falsehood. That good old Pope had been honestly dead and buried 57 years before the appearance of this Irish Bull. F. Mahony was still living in 1650, at Lisbon, but far advanced in years.
