Catena Aurea on John 3:16–18: Gregory the Great

Or thus: In the last judgment some perish without being judged, of whom it is here said, He that believeth not is condemned already. For the day of judgment does not try those who for unbelief are already banished from the sight of a discerning judge, are under sentence of damnation; but those, who retaining the profession of faith, have no works to shew suitable to that profession. For those who have not kept even the sacraments of faith, do not even hear the curse of the Judge at the last trial. They have already, in the darkness of their unbelief, received their sentence, and are not thought worthy of being convicted by the rebuke of Him whom they had despised Again; For an earthly sovereign, in the government of his state, has a different rule of punishment, in the case of the disaffected subject, and the foreign rebel. In the former case, he consults the civil law; but against the enemy he proceeds at once to war, and repays his malice with the punishment it deserves, without regard to law, inasmuch as he who never submitted to law, has no claim to suffer by the law.
