The following list contains examples of references formatted for religious and classical materials. The Chicago Manual of Style (CMOS) offers some guidelines for referencing Biblical and Scriptural materials, but if significant scholarship in Theology is being conducted, CMOS recommends the use of The SBL Handbook of Style.
The relevant Chicago Manual of Style chapters are linked to so that more information can be located easily in the online manual.
In running text, books of the Bible are written in full:
... According to Genesis 1:27, God created man in his own image.
Abbreviations are appropriate within the text in parentheses, or where there are many references to list without parentheses:
... There are several instances where bread is used in a figurative context (Isa 55:2; 1 Cor 10:17; 2 Cor 9:10)...
... Bread is used in a figurative context in Isa 55:2; 1 Cor 10:17; 2 Cor 9:10...
Abbreviations are are also used in footnotes:
5. Isa 55:2; 1 Cor 10:17; 2 Cor 9:10.
Parenthetical or footnote references to the Bible should include book, chapter, and verse (never a page number).
Bibliography entries are not required.
Sacred works of other religious traditions can be treated in a similar way to the Bible and should be cited in the running text and footnotes, but not in the bibliography.
...can be compared to the Qur'an verse (19:17-21) where it mentions that Mary gave birth to Jesus.
6. Qur'an 19:17-21.
Use the shorter form abbreviations (without full stops) for references to books of the Old and New Testament .
Identify which version you are using in the first footnote. Use either the complete name or an accepted abbreviation, e.g.:
6. 2 Kings 11:8 (New Revised Standard Version)
6.2 Kings 11:8 (NRSV)
Commonly used English names for cities in languages other than English are usually preferred, e.g. use Vatican City: Vatican Press for Citta del Vaticano: Libreria Editrice Vaticana.
If in doubt, you can use the name of the city as it appears within the source.
