Dew was on the staff of Holy Cross College, Mosgiel, the New Zealand national seminary, from 1988 to 1991. He was director of a special programme focussing on human development and gave a general introduction to first year students on prayer, scripture and the Church. He also led small groups of students ("moderator groups") who met regularly for prayer and discussion.[5]
During his time at the seminary a major concern related to the selection of seminarians. In his 1991 First Year Moderators Report, Dew expressed a real sense of frustration at the unsuitability of many students. He pointed out that "we at the Seminary can work only with those who are sent to us." Many, he suggested, were sent with unresolved issues relating to identity, sexuality and alcohol. Such students placed a heavy burden on staff and had a negative impact upon other students and group dynamics. Dew urged that in the future, diocesan vocations directors pay particular attention to eight issues with evaluating prospective students: basic knowledge of the Catholic faith; familiarity with meditation, prayer and the scriptures; a reasonable comfort with affectivity; personal independence; social comfort; intellectual curiosity; generosity; and a genuine desire and free decision to enter the seminary.[5]
Parish priest
Dew studied spirituality at the Institute of St Anselm, Kent, England, from 1991 to 1992. Upon his return to New Zealand he was appointed the parish priest at St Anne's Parish, Newtown, a post he held from 1993 to 1995.[4]
Episcopal ministry
He was appointed as auxiliary bishop for the Wellington archdiocese on 31 May 1995 at the age of 47. The news of his appointment had been announced to a large congregation at the Chrism Mass on 12 April. "The news was greeted with prolonged and enthusiastic applause."[6] Because Sacred Heart Cathedral would not have held the expected congregation, he was consecrated bishop in the Wellington Town Hall which was filled to capacity. He took as his motto "Peace through Integrity".[7] He became the Secretary of the New Zealand Catholic Bishops' Conference and acted as New Zealand Bishops' Conference representative on the National Council for Young Catholics.[4]
Pope Francis accepted Dew's resignation on his 75th birthday, 5 May 2023 on which date he was succeeded by Paul Martin, his coadjutor archbishop.[12] His resignation as head of the Military Ordinate of New Zealand was accepted on 27 May.[13]
Recalling a few weeks later how he received the news he was being made a cardinal, he said: "Since then I have received nothing but love and support, messages of congratulation. By 7am, in my first radio interview for the day, I happened to say 'I am an ordinary Kiwibloke.' Since then the words have been repeated back to me often, but I [still] believe this to be true."[21]
Dew achieved some prominence at the Synod of Bishops on "The Eucharist: Source and Summit of the Life and Mission of the Church" at the Vatican in October 2005 when he proposed that divorced and remarried Catholics should be able to receive the Eucharist. He said that bishops have "a pastoral duty and an obligation before God to discuss and debate the question." He urged the assembly to reconsider the Church ban, referring to it as a "source of scandal", adding "Our Church would be enriched if we were able to invite dedicated Catholics, currently excluded from the Eucharist, to return to the Lord's Table."[9][25] After this 2005 speech, Dew discussed the issue with Cardinal Jorge Mario Bergoglio, the future Pope Francis.[19]
Welcoming and accepting
Dew has also said, "what's the point in judging people and condemning them, but to make it clear what the church says but in such a way that you are welcoming and accepting."[19] "When church teaching is explained in such a way that it says to people they’re intrinsically disordered or they’re living an evil life, people feel they can’t meet the mark rather than it being something helping, supportive and encouraging."[26]
Curia
In relation to Curia reform, Dew has said that he "would like to see ... local communities and diocesan bishops being able to dialogue with curial bishops in a way that truly reflects collegiality" and that the "Curia is to be at the service of the church and her people."[27]
Climate and trafficking
In February 2015, Dew said he and Soane Patita Paini Mafi of Tonga, who was soon to become a cardinal alongside him, wanted to highlight two issues: the effect of climate change on the countries of the South Pacific and the problem of human trafficking in that part of the world.[28]
LGBT community
Cardinal Dew responded in 2018 to the Faith and Belief in New Zealand survey, which found only a third of the country identifies as Christian, down from 43 percent in 2013 and 49 percent in 2006. The main reason given for a failure to engage with Christianity was Church teachings on homosexuality – mentioned by 47 percent of the respondents – with the doctrine of Hell closely following, at 45 percent. Dew said Church leaders have fallen short,
"especially with regards to particular groups in society, such as the LGBT community, who have felt a very real sense of rejection through the Church, or perhaps in falling short in fully meeting the needs of our recent migrant communities."[29]
