[2] In 1959, the Lutheran Church – Missouri Synod (LCMS) had responded favorably to an invitation to discuss the formation of a new inter-Lutheran organization, with meetings in 1960 and 1961 leading to agreement to form LCUSA.
This represented a change in the LCMS's position in that it had previously required full doctrinal agreement to be established before joining an organization like this.
It did so only with the agreement that all members of LCUSA participate in doctrinal discussions.
[2] The group of congregations that had supported Seminex and left the LCMS formed the Association of Evangelical Lutheran Churches (AELC) in 1976 and subsequently joined LCUSA.
[4] The 1988 merger of the ALC, the AELC, and the LCA to form the Evangelical Lutheran Church in America made LCUSA unnecessary and it was dissolved.
