De Principiis

³ It is to be borne in mind, however, that certain beings who fell away from that one beginning of which we have spoken, have sunk to such a depth of unworthiness and wickedness as to be deemed altogether undeserving of that training and instruction by which the human race, while in the flesh, are trained and instructed with the assistance of the heavenly powers; and continue, on the contrary, in a state of enmity and opposition to those who are receiving this instruction and teaching. And hence it is that the whole of this mortal life is full of struggles and trials, caused by the opposition and enmity of those who fell from a better condition without at all looking back, and who are called the devil and his angels, and the other orders of evil, which the apostle classed among the opposing powers. But whether any of these orders who act under the government of the devil, and obey his wicked commands, will in a future world be converted to righteousness because of their possessing the faculty of freedom of will, or whether persistent and inveterate wickedness may be changed by the power of habit into nature, is a result which you yourself, reader, may approve of, if neither in these present worlds which are seen and temporal, nor in those which are unseen and are eternal, that portion is to differ wholly from the final unity and fitness of things. But in the meantime, both in those temporal worlds which are seen, as well as in those eternal worlds which are invisible, all those beings are arranged, according to a regular plan, in the order and degree of their merits; so that some of them in the first, others in the second, some even in the last times, after having undergone heavier and severer punishments, endured for a lengthened period, and for many ages, so to speak, improved by this stern method of training, and restored at first by the instruction of the angels, and subsequently by the powers of a higher grade, and thus advancing through each stage to a better condition, reach even to that which is invisible and eternal, having travelled through, by a kind of training, every single office of the heavenly powers. From which, I think, this will appear to follow as an inference, that every rational nature may, in passing from one order to another, go through each to all, and advance from all to each, while made the subject of various degrees of proficiency and failure according to its own actions and endeavours, put forth in the enjoyment of its power of freedom of will.

4. But since Paul says that certain things are visible and temporal, and others besides these invisible and eternal, we proceed to inquire how those things which are seen are temporal— whether because there will be nothing at all after them in all those periods of the coming world, in which that dispersion and separation from the one beginning is undergoing a process of restoration to one and the same end and likeness; or because, while the form of those things which are seen passes away, their essential nature is subject to no corruption. And Paul seems to confirm the latter view, when he says, “For the fashion of this world passes away.” David also appears to assert the same in the words, “The heavens shall perish, but You shall endure; and they all shall wax old as a garment, and You shall change them like a vesture, and like a vestment they shall be changed.” For if the heavens are to be changed, assuredly that which is changed does not perish, and if the fashion of the world passes away, it is by no means an annihilation or destruction of their material substance that is shown to take place, but a kind of change of quality and transformation of appearance. Isaiah also, in declaring prophetically that there will be a new heaven and a new earth, undoubtedly suggests a similar view. For this renewal of heaven and earth, and this transmutation of the form of the present world, and this changing of the heavens will undoubtedly be prepared for those who are walking along that way which we have pointed out above, and are tending to that goal of happiness to which, it is said, even enemies themselves are to be subjected, and in which God is said to be “all and in all.” And if any one imagine that at the end material, i.e., bodily, nature will be entirely destroyed, he cannot in any respect meet my view, how beings so numerous and powerful are able to live and to exist without bodies, since it is an attribute of the divine nature alone— i.e., of the Father, Son, and Holy Spirit— to exist without any material substance, and without partaking in any degree of a bodily adjunct. Another, perhaps, may say that in the end every bodily substance will be so pure and refined as to be like the æther, and of a celestial purity and clearness. How things will be, however, is known with certainty to God alone, and to those who are His friends through Christ and the Holy Spirit.
