Ok, I just opened my Fundamentals of Catholic Dogma by Ludwig Ott. What to the little citations mean like D 853 in the text? For example, there are a bunch on page 379 under Transubstantiation. I couldn’t find a key after a flip-through.
Marco, the D is a reference to Denziger; this link explains it:
My *Fundamentals of Catholic Dogma *is a Tan publication and the key to the Abbreviations is under the FORWARD To the Second English Edition P vii
Hope that helps
