2. Delahogue was Professor in Dublin where his theological works were published in several volumes in 1829. The type of instruction then given in an Irish seminary to students of Roman theology may be understood from the fact that Delahogue asserts that the doctrine that the Roman Pontiff, even when he speaks ex cathedra, is possessed of the gift of inerrancy or is superior to General Councils may be denied without loss of faith or risk of heresy or schism.
To justify this position appeal is made among others to Cardinal Perron who, although himself a supporter of the doctrine of papal inerrancy, assured King James I. that the question was not a hindrance to Ecclesiastical Reunion; since whichever view his Majesty might adopt he would none the less on either side be recognised as Catholic.
Delahogue appealed also to the fact that no reference to Papal Infallibility occurs in the Creed of Pius IV. Bossuet's famous exposition affirmed that matters disputed in the schools of theology, and invidiously brought forward by Calvinistic doctors, were no part of the Catholic Faith; and Bossuet's Exposition was endorsed by a brief of Innocent XI. Delahogue also pointed out that inferences from the figurative comparison of the relation between the Pope and the Church to that between the human head and body must be drawn with discretion. The effect of decapitation upon the human body differs from that of the death of a Pope upon the Church. Indeed the latter is essentially the same in spite of a long interregnum, or a schism, or a doubtful succession of forty years. Similarly, it does not follow that an ex cathedra fallacious utterance would be the Church's ruin.
