Joseph Alan Johnston Campbell was a Northern Irish Pentecostal pastor and Orangeman from Belfast. He founded and served as pastor and director of the Restored Open Bible Ministries in Northern Ireland. He was an author on Bible studies, a lecturer in the British Israel movement and an advocate of white supremacy. Strongly opposed to Catholicism, Campbell published anti-Catholic literature and argued that the white Celto Anglo Saxon peoples of the world represent the lost tribes of the northern kingdom of Israel. He was known in Historicist circles due to his denial of the Westminster Confession of Faith, while Fundamentalist Protestants rejected his teachings as not being biblical.
Although not a leading figure, Campbell was unapologetically loyalist and racist in his views. He was connected to activities by loyalists, including terrorism, from the early days of the Troubles. Although not named, Campbell was often referred to as “The Pastor”. He had a strong association with prominent paedophiles John McKeague and William McGrath. Later he was friends with convicted loyalist paramilitaries Clifford Peeples, in particular, and Kenny McClinton.
