Inkpin was born in England. She completed a PhD in theology at Durham University in 1996, with a thesis titled "Combatting the 'Sin of Self-Sacrifice'?: Christian Feminism in the Women's Suffrage Struggle: 1903–1918".[2][3]
Inkpin taught history and theology at Oxford University.[2] She was ordained a deacon in 1986 and a priest in 1987.[4] She has noted that the role of priest allowed her to "exist in a way between sexes – in previous centuries they called it the third sex".[1]
Inkpin and her wife Penny served in the Church of England before moving to Australia.[5]
Inkpin made a public statement in July 2017 announcing her transition.[6] At this time she was aged in her fifties and had felt that she was a woman for many years.[7] She chose the name "Josephine" in honour of Josephine Butler, an Anglican saint and theologian.[4]
In March 2021, Inkpin was inducted at Pitt Street Uniting Church, Sydney. This made her the first openly transgender person appointed within a mainstream church in Australia.[5][9][10][11][12] On 4 May 2021, local member of parliament Alex Greenwich issued a community recognition statement congratulating Inkpin on her appointment, noting that Inkpin and Jones were passionate, welcoming and focused on inclusion within the church.[13]
Inkpin was the co-chair of the Anglican Church Southern Queensland Reconciliation Action Plan Working Group. She was also coordinator of the Rainbow Faith project.[4]
Inkpin is married to Penny Jones, also an Anglican priest.[1] They met in the early 1980s while they were both studying theology at Ripon College, Cuddesdon. They have twin daughters and are also grandparents. In July 2020 they celebrated their 35th wedding anniversary and reaffirmed their vows at St John's Cathedral, Brisbane.[4]
