The historic episcopate

The historic episcopate is the claim that a church's bishops stand in an unbroken, traceable line of ordination reaching back to the apostles of Jesus, each bishop having been consecrated by other bishops themselves validly consecrated in the same chain, all the way back to the apostolic generation. Episcopacy itself, church government organized around the three offices of bishop, priest and deacon, became established in the main centers of Christianity by the second century, and the idea that a bishop's authority depends on standing in this kind of traceable succession from the apostles developed alongside it as a way of anchoring a bishop's teaching authority in continuity with the apostles' own teaching rather than in the bishop's personal claim alone. Roman Catholic, Eastern Orthodox and Anglican churches have all maintained versions of this claim, holding that their own bishops can be traced back through this chain of consecration, while treating a church that lacks bishops standing in the historic succession, most Protestant churches that emerged from the Reformation without retaining the office of bishop, as lacking something these traditions consider a mark of full ecclesial continuity, even where they otherwise recognize such churches as genuinely Christian.

The historic episcopate holds a distinctive and somewhat unsettled place within Anglicanism itself. The Church of England and the wider Anglican Communion retained bishops at the Reformation, unlike most continental Protestant churches, and Anglican bishops trace their own consecrations back through the pre-Reformation English church into the same claimed apostolic chain that Rome and Constantinople claim for their own bishops. The 1888 Lambeth Quadrilateral named the historic episcopate as one of four elements, alongside scripture, the Nicene Creed and the two dominical sacraments, that Anglicans proposed as the basis for reunion with other Christian traditions, giving it formal standing as a defining Anglican commitment. Anglicans have never been fully united, however, on exactly what kind of necessity the historic episcopate carries. Anglo-Catholic Anglicans have generally treated it as necessary to the church's very being, so that a church without bishops in valid apostolic succession lacks something essential to being a true church in the fullest sense. Other Anglicans, drawing on the tradition's more Protestant wing, have held it necessary only to the church's well-being, a valuable and apostolic pattern of order worth preserving but not something whose absence voids another church's genuine standing as Christian. That unresolved internal disagreement has shaped, and often complicated, Anglican ecumenical negotiations with other Protestant churches for well over a century.
