John Warwick Montgomery, Law and Gospel: A Study in Jurisprudence (Christian Legal Society 1978).
This 50-page monograph is designed as a study guide on the basic law school subjects. There are 20 extremely short sections, most covering one topic in one or two pages. (For example, the Torts section is two pages long). In the section, Dr. Montgomery sets out a brief discussion, usually with quotations from scripture or case law. He then poses a handful of questions based on the text, along with some scripture references for further study. This little text will reward a close reading. Each section is short enough that it can be covered in small bites.
