I did a google on churches in Gorham, ME and there are quite a few.

I didn't realize there were different types of Lutheran churches however I guess I should have thought of that since there are different types of Baptist churches. My husband is Lutheran and I have a bro in law who is a Lutheran pastor but I believe all the Lutheran churches in my area are of the MO Synod affiliation. This area is mostly Catholic and Lutheran and the town has schools of both affiliations as well.
You do have a MO Synod Lutheran church in Gorham .... Redeemer Lutheran Church...........this is their mission statement and they have sermons to listen to as well http://www.forministry.com/USMELUCMSRRRRR/MissionStatement.dsp

Maybe God wants you to step outside of the box. Pray about it, visit around and look for a Bible believing church that delves into the word and not just a "feel good" message.
