Yes. I know this carving, searched for it and attached my own words describing it.
now you seem to be telling me you are not saying that the Holy Spirit was dictating
I am fine with "dictating". The pope was writing always behind a curtain. A scribe or a servant decided to peek in, and saw something that he interpreted as the Holy Ghost whispering to the Pope. Depending how literally you take this story, you can also say "dictated". The use of the word does not imply "canonical" though.
Where in the "language of Art" (capital "A" art, we should all take note) is there some difference between "dictated by" and "inspired by" that could apply those meanings being so interchangeable in regards to the Holy Spirit itself?
Medieval art is concrete in its methods: it does not, for example, rely on naturalistic depiction of emotion through the features of the human face or body. So when a medieval artist takes up the task of depicting inspiration by the Holy Ghost, he will show a dove whispering in (or at least leaning toward) the ear. Likewise, for example, St. Lucy is shown holding up her eyes in her hand, as well as looking at the faithful with another pair of eyes in their natural place, -- not to suggest that she gouged her own eyes but to give a concrete representation of her voluntarily submitting herself to torture. Make a habit of looking at sacred art and avoid anything later than, say, 18 c. and gradually the art will speak to you. Good question, thanks.
I need write like a prosecuting attorney
Yes. Very common among your co-religionists: Protestantism always seeks to destroy something.
from your own mind
Of course. I have the mind so I use it. But I check back with the Church Whose mind I intend to share.
