aeviternal adjective1 •Pertaining to aeviternity, a state between eternity, which is unchanging and outside of time, and temporality, which is subject to change and to death or annihilation. Things aeviternal are creations, like the temporal, but everlasting, like the eternal.It is hard because it is very difficult to convert our thinking from the physical to the spiritual; from time to aeviternal and more so to eternity. — 2014
