The Archdiocesan Synod in 2026 is the next step in the ongoing process of Church renewal.

The Synod provides assistance to the Archbishop in his ministry and leadership for the good of the whole Archdiocesan community. This is achieved by the participation of representatives of the faithful, lay and ordained, of the Archdiocese of Adelaide in ecclesial discernment of communion, participation and mission, to progress the pastoral priorities identified in recent Diocesan Assemblies.

The requirement for a Diocesan Synod was a decree of the Plenary Council that all diocese hold a synod within 5 years of the close of the Plenary Council.
