In the established
Church of England, assistant bishops are usually retired (diocesan or
suffragan) bishops – in which case they are
honorary assistant bishops. Historically, non-retired bishops have been appointed to be assistant bishops – however, unlike a diocesan or suffragan they do not hold a see: they are not the "Bishop of Somewhere". Some honorary assistant bishops are bishops who have resigned their see and returned to a priestly ministry (vicar, rector, canon, archdeacon, dean etc.) in an English diocese. A recent example of this is
Jonathan Frost,
Dean of York, who was also an honorary assistant bishop of the
Diocese of York, with membership of the diocesan House of Bishops (i.e. sits and votes with the archbishop and bishops suffragan in Diocesan Synod).
Ex-colonials From the mid-19th to the mid-to-late 20th centuries, with the population growth of England, diocesan bishops sought out various levels of episcopal assistance. Suffragan bishops had been legally possible but never appointed for over two hundred years, and there were many ecclesiological, pragmatic and theological objections to their use. So Ordinaries took to appointing Englishmen who had been consecrated bishops for the colonies as
stipendiary assistant (or
coadjutor — without right of succession) bishops in their diocese, often with another post such as an especially notable (or lucrative) living. As this practice increased, it drew heavy criticism for depriving those colonies of 'their' bishop. The trends of 'returning' bishops slowly faded with the resumption of old and erection of new suffragan sees, which started in 1870 with
Dover and
Nottingham and continued steadily till
Brixworth in 1989. These bishops were titled quite inconsistently, and referred to as assistant bishops, coadjutor bishops, and even as suffragan bishops; the most stable forms were "Assistant Bishop of {Diocese}" and "Bishop {Surname}".
Recent stipendiaries From 1987 until 2016, there were two successions of assistant bishops who were active rather than retired: the
Assistant Bishop of Newcastle and the
Assistant Bishop of Leicester. In practice, they acted almost exactly like a
suffragan bishop (those dioceses had none), whereas they were actually
stipendiary assistant bishops. Following the passage of the Bishops and Priests (Consecration and Ordination of Women) Measure 2014 by
General Synod, further appointment to these roles was made untenable. Therefore, when their incumbents retired in 2016 and 2017 respectively, they were replaced with
suffragan bishops: the
Bishop of Berwick (a see abeyant since the 16th century) for the
Diocese of Newcastle, and the
Bishop of Loughborough (a newly erected see) for the
Diocese of Leicester. ==Anglican Church of Australia==
