There is a group within the LCMS having some success in trying to make the LCMS like WELS, they call themselves steadfast lutherans. Each year LCMS has less members, perhaps the steadfast lutherans will succeed and its membership will be just like WELS. In the meantime there is a growing and new church growing out of the ashes of the ELCA, that of LCMC(Lutherans in MIssion for Christ).
My brothers church joined the LCMC when they finally fled the ELCA. The only issue I see with the LCMC is they are short on organization, governing documents, etc. The only common thread among them is most of their congregations are refugees from the ELCA. Hopefully they will evolve into a strong synod with well set out doctrinal standards to prevent a repeat of what happened in the ELCA.
