Next are two separate quotes from Athenagoras:
For if the world, being made spherical, is confined
within the circles of heaven, and the Creator of the world is above the
things created, managing that by His providential care of these, what
place is there for the second god, or for the other gods?
and
Beautiful without doubt is the world, excelling, as well
in its magnitude as in the arrangement of its parts, both those in the
oblique circle and those about the north, and also in its spherical
form.
So, the "world, being made spherical" and "confined with in the circles of heaven". There's nothing about this that rules out once again the snow-globe view. This is yet another case of Dr. Sungenis seeing the word "sphere" and then interpreting it as proof for our living on a globe.
In fact, if you think about it, if this means that the SURFACE of the earth is a globe, and people live on the surface, then if the globe is suspended in the heavens, what exactly is the barrier between the heavens and the surface dwellers? In fact they would be on the edge of the line between the globe and the heavens ... which of course they believed to be WATERS. So with Sungenis' iterpretation, they'd have to have completely discarded the notion that there's a firmament above the earth separating the inhabitants of the earth from the waters above. So when did these Fathers abandon that notion?
This second passage probably requires some deeper analysis. So he describes "the world" (same term he used in the first passage) as consisting of "parts". And he refers to some parts being in the "oblique circle", some "about the north", and others "in its spherical form". Again we have some combination of a CIRLCE along with a SPHERE. How are the circle and the sphere related? If you recall, earlier we saw Arnobius saying that the earth is ROUND and BOUNDED by a circle. Between that passage and this one, you get the impression or a world more like this.

It would be interesting to see the original languages, to see how they use the term translated here as "world" vs. when they might use "earth". It really does appear to me that the term "world" is much bigger than just the surface of the earth, and attempting to equate the term with the surface of the earth actually begs the question about whether they're talking about a globe earth surface.
