1.) The goal of the Christian life is the knowledge of God: that is, to know by sight what one now knows by faith
But it is one and the same knowledge by which God knows his own truth and creates the universe
But every sort of knowledge is perfect only when it achieves its full actualization.
Therefore, inter alia, the goal of the Christian life is the creation of the universe.
2.) Beatitude is perfect friendship
Perfect friends share all their thoughts with another.
God’s thoughts create the universe.
All productive thoughts complete themselves in producing
Therefore, beatitude involves, inter alia, the creation of the universe.
Just Thomism

Wonderful. This is how we are images of God; how our powers of secondary causation are participations of his power of primary causation; how no act of any creature can possibly either get under way, or achieve completion, except insofar as it is reckoned by God at the eschaton.
Godel is in there, too: no particular act of knowledge is completeable, or therefore beginnable, except insofar as omniscience is complete.

Does it mean that in beatitude we will create ourselves?
