Epistles
Letters may or may not have titles. Therefore, the letter title can be omitted in the note and bibliography.
The most important pieces of information are the author, translator, series, and volume number. It is not
necessary to cite the series editor or editors. Do cite the volume editor if the editor is listed along with the
translator on the title page. The series titled is abbreviated in the note and written in headline style in the
bibliography (no italics). When citing from an ancient letter, include the letter, chapter (if applicable),
and page number. In the example below, the letter number is 15, the chapter number is 1, and the printed
page number is 43.

Texts by Church Fathers
Certain series combine several works of one author into a single volume. Both The Ante-Nicene Fathers
(ANF) and The Nicene and Post-Nicene Fathers (first and second series: NPNF
1
and NPNF
2
) follow this
format. When using these collections, each volume is treated as an edited work. Therefore one should
cite the ancient author, the title of their work in italics (not the general volume title), the translator and/or
editor of the cited work, series title and volume number (minus the general editor), and publication
information. One should first cite the chapter/section and paragraph number (if needed) and printed page
number. If the work is not divided into chapters or sections, the printed page number will suffice. NPNF
has two series. Indicate the series used with a superscripted 1 or 2. In the first example below, the chapter
number is 19, the paragraph number is 1, and the printed page number is 43.
