Franciscus Kenninck served as the eighteenth Archbishop of Utrecht from 1920 to 1937.
Following the death of Gerardus Gul, Archbishop of Utrecht, in 1920, Kenninck was consecrated by Bishop Henricus Johannes Theodorus van Vlijmen of Haarlem, Bishop Edward Herzog of Bern, and Bishop Georg Moog of Bonn.
As Archbishop of Utrecht, Kenninck appointed a commission that led to the recognition of Anglican orders by the Old Catholic Church on 2 June 1925, thus clearing a path toward restored communion between the Old Catholic Church and the Church of England.
In 1930, he was the first Archbishop of Utrecht to visit England, where, at the seventh Lambeth Conference of Anglican bishops, he declared that the Old Catholic Church recognized Anglican baptism, confirmation and communion as well.
Kenninck is also remembered for abolishing compulsory clerical celibacy within the Old Catholic Church in 1922, and for making the constitutions of the Old Catholic Church more democratic.
