David Hilliard's God's Gentlemen, originally published in 1978, remains the only detached and detailed historical analysis of the work of the Melanesian Mission. Starting with its New Zealand beginnings and its Norfolk Island years (1867-1920), the work follows the Mission's shift of headquarters to the Solomon Islands and on until the beginning of the Second World War. The Mission, which grew out of the personal vision of the first Church of England Bishop of New Zealand, George Selwyn, formally defined its field of work as 'the Islands of Melanesia' although its activities were confined almost entirely to the island groups that now make up Vanuatu and the Solomon Islands. The Diocese of Melanesia was a fully constituent diocese of the Anglican Church of New Zealand from its formation in 1861 until the creation of the autonomous Church of the Province of Melanesia in 1975. Based on a wide range of sources, God's Gentleman is the inner history of the slow growth of an important and genuinely Melanesian church.

George Brown (1835-1917) was many things during his long life; leader in the Wesleyan Methodist Church in Australasia, explorer, linguist, political activist, apologist for the missionary enterprise, amateur anthropologist, writer, constant traveller, collector of artefacts, photographer and stirrer. He saw himself, at heart, as a missionary. The islands of the Pacific Ocean were the scene of his endeavours, with extended periods lived in Samoa and the New Britain region of todays Papua New Guinea, followed by repeated visits to Tonga, Fiji, the Milne Bay region of Papua New Guinea and the Solomon Islands. It could be argued that while he was a missionary in the Pacific region he was not a pacific missionary. Brown gained unwanted notoriety for involvement in a violent confrontation at one point in his career, and lived through conflict in many contexts but he also frequently worked as a peace maker. Policies he helped shape on issues such as church union, indigenous leadership, representation by lay people and a wider role for women continue to influence Uniting Church in Australia and churches in the Pacific region. His name is still remembered with honour in several parts of the Pacific. Browns marriage to Sarah Lydia Wallis, daughter of pioneer missionaries to New Zealand, was long and rich. Each strengthened the other and they stand side by side in this account.
