But the position of these and similar authorities is made clear by Boethius, who says (V De Consolatione prosa 6), “When some people hear that Plato thought this world neither had a beginning in time nor will ever have an end, they mistakenly conclude that the created world is coeternal with the Creator. However, to be led through the endless life Plato attributes to the world is one thing; to embrace simultaneously the whole presence of endless life is quite another, and it is this latter that is proper to the divine mind.” [PL 63, 859B] Thus it does not follow, as some people object, that a creature, even if it had always existed, would be equal to God in duration. For, if “eternal” be understood in this sense, nothing can in any way be coeternal with God, for nothing but God is immutable. As Augustine says (XII De Civitate Dei cap. 15), [10]] “Time, since it passes away by its mutability, cannot be coeternal with immutable eternity. Thus, even if the immortality of the angels does not pass away in time (it is neither past, as if it did not exist now; nor is it future, as if it did not yet exist), nevertheless, the angels’ motions, by which moments of time are carried along from the future into the past, pass away. Therefore, angels cannot be coeternal with the Creator, in whose motion there is nothing which has been that is not now, nor anything which will later be that is not already.” [PL 41, 364-365] Likewise, Augustine says (VIII Super Genesis ad Litteram cap. 23), “Since the nature of the Trinity is wholly unchangeable, it is eternal in such a way that nothing can be coeternal with it,” [PL 34, 389] and he uses words to the same effect in XI Confessionum as well.
