The following is taken from the Diocese of Bath and Wells website:
Diocesan Synod can be thought of as the ‘parliament’ of the diocese.
Diocesan Synod considers matters referred from General Synod, Deanery Synods, PCCs and from individual Synod members. It formulates diocesan policy on a wide range of issues, assists the Bishops and their staff to support and oversee the work of the diocese, approves the budget, and debates important local and national issues affecting the Church.
Synod has over 200 members, 160 of whom are elected from across the diocese. Meetings are held three times a year. This helps to provide a system of democratic representation and accountability.
Synod is comprised of three houses – bishops, clergy and laity – who meet together although on some issues they vote separately.
