Time and Eternity
St. Augustine: "I know what time is until you ask me to define it."
Our images of "changeless things" are not helpful when thinking about God: rocks, gems, metals, etc.
"Time is short, eternity long" (JHN).
A succession of acts of understanding and will in a spiritual being.
The "time" of God, angels, saints, souls in Purgatory?
"Time out of time."
