Bibme.com is a VERY simple, BASIC, free online source.

            Identify the passage of the document to cite. Get "at least" the name of the pope who wrote the document, title of the document, publication date -- and for endnotes or in-text citations, get the paragraph or section number. Honorific titles such as "Pope" are not used, so Pope John Paul II would be cited as "John Paul II."  Alternate forms of citing popes: could also be listed as either "Catholic Church";  or "Catholic Church, & Francis".For an in text citation, put in the Latin name of the Document and paragraph number – e.g., to cite the first paragraph in the section on "Eternal Newness" in Pope Francis' Apostolic Exhortation, Evangelii Gaudium  - paragraph 11:  The in-text citation is: (Evangelii Gaudium, §11)  - Try Neil's Toolbox link below - a free online bibliography generator just dealing with the Harvard Style...

To get the paragraph symbol (§) when using MS Word  – go to "Insert" Tab – then to "Symbol" tab on right with blue omega on it – once you've drilled down a level - on right side - change "Subset" to "Latin-1 Supplement" and the paragraph symbol is in the 7th box in the third row….

These "general guidelines' are based on MLA style. Always follow your instructor's requirements, advice, or suggestions, however.

·          A first citation must be complete. Subsequent references are abbreviated in standard forms. Many well known texts are then cited (in the text of your paper even using endnotes) simply by the customary Latin title (first few words) like Divino Afflante Spiritu. 

·          A work issued by the overall Church (like the Catechism, or any Vatican II document) is cited ONLY by its title from the publication information. No need to precede the cite with Catholic Church as author. If in doubt, ask.  Still, some variations are common in church document citation, depending on the audience and sources being cited, or the advice of the instructor. 

·          In MLA style, honorific titles like "Pope," "Father" or "Cardinal" or "D.D." are not added after, or before, a name.  

·          If a document is issued by a constituted church body or organization (rather than by an individual as ecclesiastical authority) use the title page information as far as practicable. Also cite the group's name from the title page, preferring an English version if given (this is often not the case in CLICnet records).

·           In theology and church writings, citing the paragraph or section number of a work is regular practice.  This is often preferred over MLA style of page number citation in the actual edition consulted. Nonetheless, it is usually acceptable to use paper numbers from the publication. Check with your instructor - he or she may ask you to cite by paragraphs or section numbers alone and not page numbers. Always follow your instructor's requirements in every case. Be sure to ask if in doubt.  

   In theological research, simply citing paragraph or section numbers is a standard practice, often preferred over the page number in the actual edition "in hand."  Still, it is usually perfectly acceptable to use the publication page numbers.

• This is in Turabian

When citing a canon of church law, lower case is used: canon 15 § 3 3^o   

[In MS Word: To find the font for the above symbols, first choose the “Insert” tab.  Then at the far right is the symbols tab (an Omega Greek letter with the word “Symbol” under it.) You will find them in this collection of symbols.]

 [Or you can press the Alt key, press (on the numeric keypad) the 2 key, press the 1 key, lift the Alt key. The § appears]
