On the Soul and the Resurrection continues, as St. Macrina moves back into more speculative territory. She really seems to have liked the idea of the soul swanning around in the world in atoms. Well, that hadn’t all been worked out yet, so she had a right to speculate.
We also get some very fun similes, which she uses for how the soul hangs out with atoms, but which St. Greg points out are more suited to proving the possibility of resurrection in the exact same body.
We also have more fun with Greco-Roman speculation about the antipodes. Apparently some people, pagans and otherwise, thought Hades was logically on the opposite part of the globe to where they lived, and that this constituted “the underworld”. If St. M had believed this, she’d have believed her soul was somewhere out in the Pacific Ocean between New Zealand and South America. So it’s a good thing she knew souls were immaterial and not bound by place! (Antipodemap.com figures this stuff out for you, btw.)
