Gettysburg College's Lutheran affiliation was mentioned in a Dec. 19 Inside Higher Ed article.

Interviewing at Church-Related Colleges
If you get an interview at the American Historical Association or another meeting with a church-related college, you need to do your homework. What kind of church-related college is it? A good place to start is Robert Benne's Quality With Soul. Benne identifies four different types of church-related colleges. I have charted my own course in this post, but have relied on some of Benne's classifications.
There are many schools that have historic connections with Protestant denominations. This, of course, does not mean that those connections will have any bearing on the hiring process or the AHA interview. For example, Duke University has a historic connection to the United Methodist Church, but this connection will play no factor in the search process. The same might be true of a place like Gettysburg College, a school with connections to the Lutheran Church. If you have an AHA interview with this kind of church-related school, there is no need to treat it any differently than you would an interview at a nonsectarian school or public university. You may not even realize that you are interviewing with a church-related school!
