They've even got a Bible school run out of Shippensburg University, a state university in Pennsylvania that has an enrollment of over 7,000 students (the univ. not the Bible school). It looks like just a week-long course. I couldn't help but think of the week-long KM schools for elders in the WT org.

It looks as well like they have a creed. Click on the "Fellowship" link and see the brief comment on "the Birmingham Amended Statement of Faith... as historically practiced by the Central Community." Did your doorman mention any of this?
