And when all things shall be subdued unto him, then shall the Son also himself be subject unto him that put all things under him, that God may be all in all.
All Commentaries on 1 Corinthians 15:28 Go To 1 Corinthians 15
Augustine of Hippo
AD 430
Even if there is no chance of manumission, slaves are now to make their slavery a kind of freedom by serving with love and loyalty, free from fear and feigning, until injustice becomes a thing of the past and every human sovereignty and power is done away with, so that God may be all in all.
