The only way to make sense of your comment is to conclude that I have a much higher standard for real theologians than you do apparently.

But I will say that few non-theologians have had the religious formation that I've had.  How many non-theologian engineers have had graduate-level courses in each of the following topics?

- fundamental theology
- moral theology
- metaphysics
- bioethics
- history of the Church
- the Trinity
- the Ten Commandments
- Fides et ratio
- Vatican II documents

And I flatly and happily admit that while I did very well in each of these classes, I know nothing at all compared to my professor priests.  And most of them don't consider themselves to be formal theologians. 

It's a matter of standards and criteria.
