In the Anglican Communion, the model of government is the 'Bishop in Synod', meaning that a diocese is governed by a bishop acting with the advice and consent of representatives of the clergy and laity of the diocese. In much of the Communion the body by which this representation is achieved is called the diocesan synod. (In the Episcopal Church in the US, the corresponding body is called a diocesan convention.)
The precise composition of a diocesan synod is subject to provincial and local canon and practice.
In the Church of England diocesan synods exist under the terms of the Synodical Government Measure 1969.[1]
A diocesan synod consists of three Houses, as follows:
Clergy and lay elected representatives are elected for a three-year term of office. The first diocesan synods met in 1970, and elections have been held every three years since, most recently in 2018. Election is by the members of the deanery synods of the diocese, and the number of representatives of each deanery is in proportion to the total number of 'members' of the churches in that deanery, compared with the diocese as a whole. The House of Clergy and the House of Laity should have approximately the same number of members. The method of election may be by simple plurality (i.e., first past the post) or by single transferable vote, and each diocesan synod may choose between these two.[2]
In general the three Houses of the diocesan synod meet together, debate together and vote together, and a majority is assumed to be a majority of each of the three Houses. However, a vote by Houses can be requested, and in certain cases is required. In a vote by Houses, the consent of each of the three Houses is required in order for the assent of the Synod to be given. In addition, the diocesan bishop may declare that the House of Bishops shall only be deemed to have assented if the assenting majority includes the bishop. This means that the diocesan bishop may exercise a veto over the diocesan synod if they so wish.
See main article: article and Anglican Church in Aotearoa, New Zealand and Polynesia. The governing bodies of Episcopal Units in the three-tikanga church are each referred to by names appropriate to their tikangas language: the New Zealand and Polynesia dioceses by diocesan synods, Te Pīhopatanga o Aotearoa by te rūnanganui ("great assembly") and the other pīhopatanga by hui amorangi. These smaller pīhopatangas hui amorangi ("governing bodies") are not exactly equivalent to diocesan synods in that they are not fully independent of te rūnanganui.[3]
