Ronald Owen Hall CMG MC* (Chinese: 何明華; Jyutping: Ho Ming Wah; pinyin: Hé Mínghuá; 22 July 1895 in Newcastle upon Tyne – 22 April 1975 in Lewknor, Oxfordshire) was an English Anglican missionary bishop in Hong Kong and China in the mid 20th century.

As an emergency measure during the Second World War, with China under Japanese occupation, he ordained Florence Li Tim-Oi as the first woman priest in the Anglican Communion.

[8] He was transferred to 15th (Nottingham) Battalion, Sherwood Foresters on 9 July 1915, and subsequently to the General List with the same date, having been appointed a staff captain.

He became friends with young Chinese Christian leaders, including the evangelist T. Z. Koo (Gu Ziren) and Y. T. Wu, the founder of the Three-Self Patriotic Movement in China.

[4] Before World War II, Hall established an orphanage in Tai Po,[27] Hong Kong, which later became the St Christopher's Home.

Florence Li Tim-Oi had already been made a deaconess in Macau by Hall and had been authorised by him and his assistant to give the sacraments to the Anglicans in these extenuating circumstances.

[31] The Archbishop of Canterbury at the time, William Temple, confided to others his conflicting views but he felt compelled to take a public stand against it.

At the provincial synod of the Chung Hua Sheng Kung Hui in Shanghai in 1947, Hall tried but failed to receive retroactive approval in canon law for Li's ordination.

[39] For example, the governor of Hong Kong Alexander Grantham (1947–57) commented that one of the Hall's foundations, Bishop's Worker Schools, was "completely communist-dominated and centres of communist and anti-British indoctrination.
