An incident occurring in Kikuyu, British East Africa, 1913. The Anglican Bishops of Mombasa and Uganda participated in a communion service with Presbyterian missionaries and otherwise compromised the traditional Anglican position. Doctor Frank Weston, Anglican Bishop of Zanzibar, an extreme "Anglo-Catholic," protested in an open letter to the Archbishop of Canterbury, denouncing these bishops as guilty of heresy and demanding their trial. The incident created a wide stir in ecclesiastical circles and threatened for a time to disrupt relations between high and low Churchmen in all parts of the world.
