Understanding better the context of the project after looking at the Schaff's arrangement, it appears more apt for me to simply conform to the indications given in each section.The reason I took such a short extract is that I'm following Schaff's arrangement but where he doesn't give an English translation, I've gone and found one. So the marked text is just the English paragraph that he gives only in Greek and Latin. He does give some context as you can see via his notes but I agree that without them, it's truncated. Since we can't read his notes followed by the English translation in one files, if you want to give a fuller version, I'd suggest reading the entire thing (p.344-346).
Here, then, is the first and briefest of the sections assigned to me:
18 The Creed Of The Sixth Œcumenical Council, Against The Monothelites A.D. 680
