When referencing the scriptures, one verse can have many titles. Do you use John 3:16, St. John 3:16, Saint John 3:16 or St John 3:16?

These exports standardize on a format that the Church of Jesus Christ of Latter-day Saints has provided in their canon of scripture.

If you look at the front of your Book of Mormon you'll see a page with the title Abbreviations and Designations in Footnotes and Index, and this is the formatting scheme used. So in the case of our example, the verse would be referenced as “John 3:16” in the indexes and footnotes.
