I don't know about all brands of Lutherans, but I know some of them are astonishingly conservative. The Church of the Lutheran Confession, for example, doesn't allow women to preach, teach, or vote; doesn't allow nonmembers to take communion; doesn't allow its members to join fraternal organizations (including the Boy Scouts!); and doesn't allow any kind of cooperative activity between CLC churches and non-CLC churches or organizations.

My ex-wife was a member until she was formally excommunicated because she told the pastor she didn't believe some of their doctrines.

The Lutherans that sponsor Holden Village, on the other hand, are quite liberal. I think they even use Catholic hymnals!
