Theology is not present in universities, religious studies is (edit: by theology I meant the study of God, not the study of religion: that's not quite right as you can see in my replies). Theology is taught in special schools, because it fundamentally does not work the same way as other studies. In Universities, there is an expectation that no specific category of ideas should be preferred above any other unless it beats out its competition on the grounds of convincingness or support by evidence. Learning new theology is quite close to learning anything else, but research is very different!

In fact, there's also a little gap inside the universities, between people who primarily rely on evidence (the sciences), and people who primarily rely on being convinced (the humanities). So you've got faith, evidence, and convincingness, and their followers find it difficult to talk.
