I have begun reading over some of the documents from the Vatican II council to familiarise myself with the material for when I talk with people that I know that are catholic, and I am having troubles understanding the footnotes.
The first footnote in the first constitution (Called "The Word of God") is as follows: cf. St. Augustine, "De Catechizandis Rudibus," C.IV 8: PL. 40, 316.
I have deduced some of this as meaning: confer to "De Catechizandis Rudibus," however, it is the rest that throws me for a loop. Primarily, PL. and I believe C. means circa.
THESE ARE SOME MORE EXAMPLES:
f. Council of Trent, session IV, loc. cit.: Denzinger 783 (1501).
cf. Second Council of Nicea: Denzinger 303 (602); Fourth Council of Constance, session X, Canon 1: Denzinger 336 (650-652).
Cf. Ibid. 33, 35.
Perhaps some of these require an understanding of various other catholic texts, but is there a list where I can find abbreviations and shorthands like these?
