Probably, there will be some review but I doubt there would be a complete Catechism. That was not my case, at all but then I went through Catechism before the American Lutheran Church became part of the ELCA.
Please contact your nearest LCMS. We did and couldn't be happier. This also seems to be the prevailing attitude of those former ELCA members who have gone to LCMS.
Thanks for your information. I, too, had Catechism under the American Lutheran Church before all the name changes began to float by.
However, I don’t think I’ll look into changing as long as Mom is alive.
