The result of all these changes on the Church communities of Small Heath was of course dramatic with congregations in each of the parishes falling to very small numbers.
Discussions took place as early as the 1970's about bringing the parishes of St Aidan, St Oswald, St Gregory and St Andrew together and for a period from the mid 1980's they became a Group of parishes.
However the effects of the changes continued, St Andrew's church was demolished and its area divided between St Martin in the Bull Ring and St Aidan.
In 1992 the remaining three parishes were amalgamated into a single parish, though still with three church buildings.
On 17th November 1992 the amalgamation of St Aidan, St Gregory and St Oswald was confirmed at the Court of Buckingham Palace.
From 1994 decisions were taken that there was need for only one set of buildings and a very extensive process of analysis and consultation was undertaken by the parish to determine the Way Forward.
The outcome was a radical set of decisions:
- To be involved in four new ways in the community together with other local Churches and community organisations
- To close and sell St Gregory the Great and its vicarage
- To close and sell the church, hall and vicarage at St Oswald of Worcester
- To redevelop the St Aidan site
- To rename the parish as All Saints
- To bring into the parish the remainder of the former St Andrew's parish, now known as Bordesley Village
- To purchase a new Vicarage in Bordesley Village
Each of these required very extensive legal, consultative and financial proceedings, which were largely completed by the end of 1998.
The decision to redevelop St Aidan's was based on its location in the parish and its potential for redevelopment.
The changes involved reversing the direction of worship, making the former baptistery into a sanctuary, and creating new entrances and community facilities.
These proposals were supported by several advisory bodies but opposed by others, leading to a Consistory Court case in 1998.
The Chancellor granted a faculty and criticised the Victorian Society’s opposition.
In August 1999 the former vicarage was converted into a community centre.
The redevelopment (1999–2001) included reversing the interior layout, creating new spaces, upgrading infrastructure, and improving access and facilities.
The old hall behind the church was demolished and replaced with a new clergy house and garden area.
The new Clergy House is now occupied by the current parish priest of All Saints.
