Journey

The term derives from the Latin 'aeternus', a contraction of 'aeviternus', combining 'aevum' (age, lifetime) and 'aeternus' (relating to age). In medieval scholastic philosophy, eternity was often distinguished from 'aevum', which represented the duration of angels and the heavens, contrasting with both temporal change and the absolute timelessness of God.
