The Sons of Light had a composite Nature.

And, therefore; if the Sons of the Light were eaten and entered into the belly and were digested in the stomach, it must be that they were dissolved in the excrement and waste [lxx] refuse. For these are plausible statements to be made by their own about their own! And, therefore, those Sons of the Light are natures which can be dissolved and destroyed. And it is proper to ask concerning this nature, as to how it existed from all eternity. For if they were compounded they are also dissolved . . . and also destroyed; they are not the thing [P. 84.] which they were before they were destroyed ; and besides this, it is clear that if he collects and compounds them, . . . has compounded them from the beginning. And if from all eternity they have not been compounded, but are natures which are not composite (they spring) from an Existence which is not composite. So that by plain things they have been refuted who speak much falsehood about secret things . . . [L. 18.] akin to the body, as they say, that body is found not only [unable] to eat or to destroy or to torture . . . but, also, it [L. 30.] is unable to understand their plain things . . . as they say, [L. 37.] [that as] the Darkness ate the Light . . . which was in it, [L. 40.] and it was all inside the Darkness . . . how did it eternally and from the beginning both seize it and feel it . . . into [P. 85, l. 7] its midst . . . and how . . .?
