As a result, the Lutheran Church in Mexico remained small throughout this period, numbering only 1,000 members in the 1910s.
[3] The Lutheran Church—Missouri Synod (LCMS) began German and English mission work in Mexico in 1922, though it was forced to abandon these efforts in 1931.
[4][5] The LCMS resumed its missionary efforts in 1940, this time in Spanish, under the name, "the Mexican Lutheran Conference of Missouri."
The first Lutheran missionaries focused their efforts in Mexico City, Monterrey, Nuevo León, and Torreón, Coahuila.
That same year, the ALC opened Casa Augsburgo, a small seminary in Mexico City.
[2][12] In 1969, the SLM became an independent sister church body of the LCMS, later joining the International Lutheran Council.
[16] As of 2019[update], it had 650 members, 6 pastors, 5 seminary students, 10 congregations, and 13 preaching stations.
A number of these congregations joined the Mexican Lutheran Church, though they were replaced by new mission plants in Puebla and Sonora.
In 1977, the remaining congregations were officially organized as the Lutheran Apostolic Alliance of Mexico (Spanish: Alianza Apostólica Luterana Mexicana or AALM).
[23] In addition to the three church bodies listed above, there are also several independent Lutheran congregations in Mexico.
