Aevum
(重定向自Aeviternity)
In Scholastic philosophy, the aevum (also called aeviternity) is the mode of existence experienced by angels and by the saints in heaven. In some ways, it is a state that logically lies between the eternity (timelessness) of God and the temporal experience of material beings. It is sometimes referred to as “improper eternity”. The word aevum is Latin, originally signifying “age”, “aeon”, or “everlasting time”; the word aeviternity comes from the Medieval Latin neologism aeviternitas.
