“Christ, he asserts, not merely opened, but broke in pieces the gates of brass, in order to make the prison useless; where there is neither door, nor bar, whosoever enters is not detained. What God destroys, who can set up again?
Earthly kings indeed set free prisoners, yet leave untouched the prison gates; but Christ broke in pieces the gates of brass. Christ went to the utterly black and joyless portion of hades, and turned it into heaven, transferring all its wealth, the race of man, into His royal treasury.
In this, too, Christ surpasseskings, for they send messengers, but He went in person to set the captives free. So again, he says: 'Our Lord, when He was in hades, set free all who were kept prisoners by death.'”
— St. John Chrysostom, 347-407 (in reference to 1 Peter)
