Much human thought has gone into the study of alchemy, astrology, Copernican theory of cosmology, and superstitions of all types. I think that the study of theology is important as a way to understand societies but by no means should it be uncritically accepted. The importance comes from how people behave and think and not because of the value of what they are thinking about.

Religion and philosophy at one time were considered to be science. This turned out to
be false. I think that one can dismiss the content of theology without dismissing the study of it. The study is important but it has to be informed and critical and not blindingly accepted as truth. Comparative religion(s) is a valuable university course as part of the humanities and there are those who know a good deal about it without having to subscribe to any of its tenets. Many of these people (scholars) know more about specific religions than their practitioners. This is particularly true of Christianity and other religions as well.
