Sixty-two percent of islanders are Christians. After the death of the first chaplain Rev G. H. Nobbs in 1884, a Methodist church was formed and in 1891 a Seventh-day Adventist congregation led by one of Nobbs' sons. Some unhappiness with G. H. Nobbs, the more organised and formal ritual of the Church of England service arising from the influence of the Melanesian Mission, decline in spirituality, the influence of visiting American whalers, literature sent by Christians overseas impressed by the Pitcairn story, and the adoption of Seventh-day Adventism by the descendants of the mutineers still on Pitcairn, all contributed to these developments. The Roman Catholic Church began work in 1957 and in the late 1990s a group left the former Methodist (then Uniting Church) and formed a charismatic fellowship. In 2011, 34 percent of the ordinary residents identified as Anglican, 13 percent as Uniting Church, 12 percent as Roman Catholic and three percent as Seventh-day Adventist. Nine percent were from other religions. Twenty four percent had no religion, and seven percent did not indicate a religion. Typical ordinary congregations in any church do not exceed 30 local residents as of 2010[update]. The three older denominations have good facilities. Ministers are usually short-term visitors.
