The WELS Constitution charters the Commission on Inter-Church Relations (CICR) to "serve under the Conference of Presidents by represending the synod in doctrinal disucssions with other church bodies who are, or are not, in fellowship with the synod in order to 'extend and conserve the true doctrine and practive of the Evangelical Lutheran Church.' "

To carry out our calling, the CICR meets regularly with representatives from various sister churches in the Confessional Evangelical Lutheran Conference for information sharing and mutual encouragement. The CIRC also assists individuals and churches that are seeking to take confessional Lutheran stances.

The CICR maintains a Lutheran churches periodical reading list and visits several conventions to stay abreast of happenings in the Lutheran world.
