Archibald Campbell (bishop)
Archibald Campbell (died 1744) was a clergyman of the Scottish Episcopal Church who served as Bishop of Aberdeen. He was the son of Lord Neill Campbell by his first wife Lady Vere Kerr; his grandfathers were Archibald Campbell, 1st Marquess of Argyll, and William Kerr, 1st Earl of Lothian. He was a student of the church fathers and the author of a book on the Middle State, in defense of prayer for the dead. He lived in England for many years and was an associate of English nonjurors including George Hickes, Thomas Brett, Thomas Deacon, and Roger  Laurence. In the usages controversy he was a staunch defender of the usages and wrote two pamphlets. When Brett engineered a reunion with the non-usager nonjurors in the early 1730s, Campbell, Laurence, and Deacon stood apart and constituted the extreme usager party. In mid-1733, after failing to find assistance from any English nonjuring or Episcopalian Bishops, Campbell proceeded to consecrate Laurence alone, and thereafter both consecrated Deacon. Due to the uncanonical nature of the consecration this breakaway group was never recognised by the regular nonjurors. The Orthodox British Church, as it became known, had congregations in London, Shrewsbury and  Manchester, the latter lasting into the first decade of the nineteenth century. Campbell died in London in June 1744.
