Each of this church's expressions—congregations, synods and the churchwide organization—has a constitution.
Each churchwide assembly has amended the constitutions.
It is recommended that ELCA congregations and synods review the adopted amendments for their constitutions as soon as possible after each churchwide assembly to incorporate the required changes and to consider the recommended changes.
The churchwide assembly meets every three years. Amendments to any synod constitution are approved by the synod assembly. Amendments to any congregation constitution are approved by the congregation at its regular meeting. These meetings are governed by parliamentary procedure. Basic information on parliamentary procedure can be found here.
