Simply put, "Turabian" is shorthand for the widely-accepted academic style guide originally published by Kate L. Turabian of the University of Chicago. Like any other style guide, Turabian prescribes specific citation styles and page layout specifications for academic writing.
The BJU Seminary uses Turabian style, and seminarians do best when they make some effort to adhere to the Turabian guidelines in their work.
Rather than spending time that you could be using for writing and researching with the details of page layout, you can use a Word template with predefined styles that follow the Turabian guidelines.
See the “Class Paper” version of the Template on the link for Dissertation Helps.
Read the instructions!
Remember that the technical helps offered here are no substitute for knowing Turabian standards (and the sometimes contradicting instructions of your teachers!).
You simply must get a copy of Turabian's book (be sure you have the latest edition), but also pay attention to any style guidelines given to you by your teachers. Know where the two contradict each other, and follow your teacher's prefs.
