There has been quite a bit of discussion about who owns the real estate and other assets - the local church, the diocese/synod/? or who...
I leave it to individuals to look after their own souls, hopefully with the help of a good pastor. I tend to be more than a bit cynical around here because I have been called a lot of things for refusing to leave the ELCA.
My wife and I left the ELCA a year ago for the LCMS. We still have friends in our old congregation and would never presume them less than faithful for staying with the ELCA.
One must follow one's conscience in all matters. The only caution I raise to them, and you, is be ever diligent in your beliefs and interaction with others. It is very easy to become lax and allow doubts or seemingly cohesive arguments creep in to ones beliefs. The heads of the ELCA have allowed Satan to play in their lot.
