Aevum

In scholastic philosophy, the aevum (also called aeviternity) is the temporal 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.

The concept of the aevum dates back at least to Albertus Magnus's treatise De quattuor coaequaevis.

[3] Its most familiar description is found in the Summa theologica of Thomas Aquinas.

[4] Frank Sheed, in his book Theology and Sanity, said that the aevum is also the measure of existence for the saints in heaven: "Aeviternity is the proper sphere of every created spirit, and therefore of the human soul... At death, [the body's] distracting relation to matter's time ceases to affect the soul, so that it can experience its proper aeviternity.
