2. If, however, it is impossible for this point to be at all maintained, viz. that any other nature than the Father, Son, and Holy Spirit can live without a body, the necessity of logical reasoning compels us to understand that rational natures were indeed created at the beginning, but that material substance was separated from them only in thought and understanding, and appears to have been formed for them, or after them, and that they never have lived nor do live without it; for an incorporeal life will rightly be considered a prerogative of the Trinity alone. As we have remarked above, therefore, that material substance of this world, possessing a nature admitting of all possible transformations, is, when dragged down to beings of a lower order, moulded into the crasser and more solid condition of a body, so as to distinguish those visible and varying forms of the world; but when it becomes the servant of more perfect and more blessed beings, it shines in the splendour of celestial bodies, and adorns either the angels of God or the sons of the resurrection with the clothing of a spiritual body, out of all which will be filled up the diverse and varying state of the one world. But if any one should desire to discuss these matters more fully, it will be necessary, with all reverence and fear of God, to examine the sacred Scriptures with greater attention and diligence, to ascertain whether the secret and hidden sense within them may perhaps reveal anything regarding these matters; and something may be discovered in their abstruse and mysterious language, through the demonstration of the Holy Spirit to those who are worthy, after many testimonies have been collected on this very point.
