Scriptural-theological interpretation with explicit metaphysical premisesIn 1 Corinthians 15, all in all belongs to Christ's resurrection, reign, defeat of death, and handing over of the kingdom to the Father. It is not a claim that God and creatures become an aggregate, or that the divine essence acquires the world's missing contribution. Given the independently defended account of divine plenitude, the new fullness is on the created side: communion, justice, embodied life, and the enjoyment of the good become actual for creatures without making God more divine.
Calling God the All can express universal sourcehood only if the needed positive bridges are supplied. Underivation excludes a source of God's actuality; it does not alone prove infinite possession of every pure perfection. Likewise, universal sourcehood does not establish every person's final destiny. The Christian conclusion is stronger and more determinate than the abstract grammar: through Christ in the Spirit, the redeemed are brought into communion with the Father. The creature finally receives its fulfillment without becoming the source, and God gives without needing the gift in order to be complete.
