In William A. Jurgens book “Faith of the Early Fathers”, Book 1, General Index is listed:
Sacraments:in general, DI 790-811; (see individually)
The abbreviation ‘DI’ is not listed under ‘Table of Abbreviations’

I cannot locate these subjects individually in any other index; can you inform me?

Yes, I can help you here. DI stands for Doctrinal Index. Go to page 426 and you will find what you are looking for. It’s before the General Index. Hope this helps…God Bless:)
