Dakin was ordained deacon in 1993 and priest in 1994. His first appointment was as Principal of the Church Army training college in Nairobi, during which time he was also an assistant curate at All Saints' Cathedral, Nairobi. He took up his appointment as General Secretary of the Church Mission Society in 2000. During this time, he was also an honorary curate of St James the Great, Ruscombe in the Diocese of Oxford, Church of England.
In January 2014, it was announced that the Channel Islands would be temporarily removed from the oversight of the Bishop of Winchester for the first time for 500 years, after relations between Dakin and the Deanery of Jersey broke down over the handling of alleged abuse, and the suspension of the Dean of Jersey. The Deaneries of Jersey and Guernsey were transferred to the direct oversight of the Archbishop of Canterbury, and the Dean of Jersey was reinstated, with Archbishop Justin Welby subsequently issuing an apology to the Dean and his wife "for the hurt and the treatment that they had received”. Dakin commissioned a report in 2013, which found that there should be no disciplinary action against any Channel Islands clergy. The full content of the report has never been published. In the face of continued poor relations, the Archbishop of Canterbury formed a special Commission in June 2018, under the chairmanship of former Bishop of LondonRichard Chartres, to decide on a way forward. The Commission issued conclusions in October 2019, stating of Dakin's original handling of the case that “The suspension of the Dean came as a seismic shock to the civic authorities and churchpeople in Jersey, and triggered a breakdown in trust between the Church and people in both Islands, and Winchester. Questions were immediately raised as to the propriety, and indeed legality, of the Bishop’s actions.” The final decision of the Commission was that the Channel Islands should not return to the episcopal oversight of the Bishop of Winchester, but should instead be incorporated into the neighbouring Diocese of Salisbury, as a new permanent arrangement for episcopal care. The new arrangement is for both Jersey and Guernsey Deaneries, as relations had broken down across all the Channel Islands. In a report prepared for a visiting delegation during the Commission process, the Standing Committee of the Deanery of Guernsey wrote of its relationship with Bishop Dakin: “While the handling of the Jersey safeguarding issue may have been the trigger for the current position, it is not the only matter which has so seriously strained the relationship."
Views
Dakin is a committee member of the Evangelical Group of the General Synod of the Church of England. In March 2014, the group sent an email to its members about the introduction of same-sex marriage in England and Wales, saying that the committee members believed that "appropriate sacramental discipline should apply to those who choose to enter into any sexual relationship other than within marriage between a man and a woman".
