Hall described 4 key characteristics of the Fathers; 1) their antiquity, 2) the holiness (or zealousness) of their life, 3) their orthodoxy, and 4) ecclesiastical approval of their teachings. With the exception of the first point, I think these also apply quite well to our latter-day prophets and apostles.
In fact, their proximity to us even brings an added benefit. While they might not provide the same kind of insights into the scriptures that the early fathers do, their modern focus can apply more directly to our own light. Our shared context can also make their exigesis more approachable to us.
Over the next couple of weeks I'll try to post some entries about conference talks from the past.
