The answer to this is obvious, i.e., that eternity belongs to God alone (simpliciter). YET, through grace, we may participate in the eternity of God in different degrees. For, by grace, we are given life that does not end AND the nature of the beatific vision is one where the thought does not shift from God and, by consequence, those things that are related to Him. Further, by nature, creatures relate to time in different ways (which will be treated in A. 4-6). Further, we may speak of eternity in a metaphorical sense, which is able to lead us, through creatures, to a certain understanding and contemplation of the eternity of God. Such as, the mountains and heavenly bodies that are stable and exist well into the past and will exist well into the future.
