He returned to Ireland in 1989, serving as a curate in Tullamore and lecturing in moral theology at St Patrick's College, Maynooth. While continuing to lecture in moral theology, Farrell was appointed executive assistant to the president of the university in 1990. He was subsequently appointed vice-president on 13 October 1993 and president on 9 December 1996, following the sudden death of his predecessor, Matthew O'Donnell.[2][3]
Following the creation of the National University of Ireland from the separation of the faculties of Arts, Celtic Studies and Philosophy and Science from St Patrick's College by the Universities Act, 1997, Farrell remained president of the pontifical university, presiding over the revision of the formation programme Pastores Dabo Vobis and supervising the renovation of its heritage buildings.[3]
Following media reports in 2002 surrounding the resignation of his predecessor, Micheál Ledwith, in 1994, Farrell made public the circumstances of Ledwith's departure, that he had been accused of sexually abusing a minor and reached a confidential financial settlement with his accuser.[4]
Following the invitation of controversial American theologian, Charles Curran, to speak at a conference sponsored by the university in 2006, Farrell stated that he had been neither consulted about, nor informed of, the invitation.[5]
Return to pastoral ministry
Farrell retired as President of St Patrick's College in 2007 and returned to pastoral ministry in the Diocese of Meath, when he was appointed parish priest in Dunboyne. He was appointed vicar general of the diocese in 2009.[6]
In 2021 when it came to same-sex blessings, he said that such situations should be dealt with “individually and pastorally”, lamenting that such blessings "are very often misconstrued as marriage".[15]
Following the release of Fiducia Supplicans, Farrell said couples in so-called irregular unions cannot be refused a blessing. He stated “prudence and attention to the ecclesial context and to the local culture” could allow for different forms of blessing, but not for “a total or definitive denial”.[16]
In 2024 Farrell said that until the sexual abuse crisis is fully addressed, there will not be “authentic, enduring renewal and reform” in the Church. Speaking at Saint Mary’s Pro-Cathedral he spoke of a “culture of denial” with respect to sexual abuse.[17]
