Select a Theologian

Choose a theologian who interests you!  Your curiosity motivates you to do the work, and to do your best.

Consider the possibilities:

  • Historical periods from Apostolic to Modern
  • Affiliations from Roman Catholic to non-denominational Christian
  • Aspect of theological inquiry from doctrinal (such as on the trinity) to perspective (such as feminist)

You do want to choose a theologian who has published something that you can use as a primary source (see the next section of this guide) and whose publication has been sufficiently analyzed (see a later section of this guide).

Having trouble?  Talk with your instructor.  Your instructor may give you a list of recommended theologians/topics or will talk with you about your interests and a suitable choice given those suggestions.

In the meantime, take a look at Britannica Academic's list of people known for theology​ or browse one of the books listed below.

Find the Primary Sources

If you know the source you want to use, search for it by title in the library catalog (in the case of a book) or by starting with the journals list at the library website (to find the full text of an article in an ejournals collection or database). Alternatively, email the citation to so that I may find the full text for you.

If you do not know the source you want to use, search for possibilities in the library catalog (especially to locate books) and the research databases (especially to locate articles). See the next section for details.  In addition, you are welcome to email with the name of the theologian and a request for help.

Cite Sources and Annotate

Prepare your citations using the notes-bibliography system, one of two techniques within Chicago style. Consult a quick guide to this style or use the library's ebook edition of the Chicago Manual of Style.

Remember that a unique format exists for passages from the Bible. Find instructions for citing scripture at

The library at the University of Toronto provides an excellent guide to writing annotations.
