National Lutheran Council. Inter-Lutheran Consultation.

The Inter-Lutheran Consultation (ILC) was formed in 1963 by the National Lutheran Council (NLC) (an agency of the Lutheran Church in America and The American Lutheran Church), the Lutheran Church-Missouri Synod (LCMS), and the Synod of Evangelical Lutheran Churches to discuss the formation of a new agency in which the bodies could participate. Sub- Committees were established to discuss and plan the structure of the new agency as well as address the agency's role in specific areas of service. The ILC's efforts came to fruition on January 1, 1967 with the formation of the Lutheran Council in the U.S.A. (LCUSA).

As the successor agency to the NLC, the LCUSA had a membership which represented 95% of American Lutherans.
