Gambold was a beloved Moravian minister and bishop. In his youth, he was a hypochondriac, melancholic recluse, though always conscientious about his clerical duties. He purportedly found solice in the Moravian church. Together with James Hutton, he became the chief translator and editor of a series of literary defences of the Moravian church in England against attacks during the 1750s, though he remained anonymous. He also employed his editorial skills as a proofreader and editor for William Bowyer, the publisher. As a Moravian, Gambold had embraced poverty. He collected and wrote original hymns, in addition to a poem on Ignatius written in 1740, but not published until after his death.
