"What is a "scientist of religion," an atheist theologian?"
No. Comparative scientific study of different religions is not a theology, and calls for the absence of religious belief in any of one's subjects of study. And just as a scientist is not a theologian, so a theologian is not a scientist - they operate in orthogonal frames of reference. The former reference frame is "of this world', and the latter is "not of this world".

"they [science/scientists and religion/theologians] operate in orthogonal frames of reference. The former reference frame is "of this world', and the latter is "not of this world"."

Disagree with this statement. Christianity at least references this world along with that not of this world. As for religion and science, they are not any more mutually exclusive than history is from art--they are two topics that at times converge.
