Surely you and Matt are far more well-versed on the Nicean council proceedings than I. I went looking just the other day. Seems like I'd spent some time looking about in the past. I was surprised by how much detail there is, but surely you guys would say that what we do know only begs more questions.
My less-informed viewpoint has me thinking this: with whatever knowledge we might acquire, it may be hard to understand some adjudications without knowing certain subcultural traits and dispositions, of the variety that are often only apparent to those who lived through the times when they were salient cultural drivers.
For example, looking ahead some 1800 years from now, how many historians in 3100 ad will be able to say how a Baby Boomer might have felt at this time about certain issues...?
