If, again, they declare that these things [below] are a shadow of those [above], as some of them are bold enough to maintain, so that in this respect they are images, then it will be necessary for them to allow that those things which are above are possessed of bodies. For those bodies which are above do cast a shadow, but spiritual substances do not, since they can in no degree darken others. If, however, we also grant them this point (though it is, in fact, an impossibility), that there is a shadow belonging to those essences which are spiritual and lucent, into which they declare their Mother descended; yet, since those things [which are above] are eternal, and that shadow which is cast by them endures for ever, [it follows that] these things [below] are also not transitory, but endure along with those which cast their shadow over them. If, on the other hand, these things [below] are transitory, it is a necessary consequence that those [above] also, of which these are the shadow, pass away; while; if they endure, their shadow likewise endures.
