Gregory the Great

Have the gates of death been opened unto thee, and hast thou seen the gloomy doors?

For the 'gates of death' are the adverse powers. Which the Lord descended and opened, because by dying He overcame their strength. Which are by another appellation called the 'gloomy doors,' because while they are not seen, by reason of their crafty concealment, they open to deceived minds the way of death. Which gloomy doors the Lord beholds; because He both observes and represses the crafty malice of unclean spirits. And did He not, by beholding, restrain them, while we know them not, our mind would both know nothing of their snares, and would be taken and perish by them. But even we behold these gloomy gates, when we are illumined with rays of heavenly light. Whence also it is said by the Prophet, The Lord is my helper, and I shall see mine enemies. He therefore Himself beholds our enemies, Who by His gift makes our enemies visible to us. Or certainly, the Lord then beheld the gloomy gates, when penetrating the barriers of the pit, He smote the cruel spirits, and by His death condemned them that presided over death. Which is here spoken of no longer as of a future, but as of a past event; for this reason, because that which He intended to do in deed, He had already done in predestination.

[MORAL INTERPRETATION]

For the gates of death are wicked thoughts: which we open to God, when we confess them with weeping in penitence. For He beholds them even when not confessed; but enters into them, when confessed. For He then in truth opens a way for Himself in the gates of death, when we have put aside evil thoughts, and He comes to us after confession. And they are called the gates of death for this reason, because the way to death is always opened through evil thoughts. Which is again repeated, when it is subjoined; And hast thou seen the gloomy doors?

For the gloomy doors are the lurking evils of the mind, which can both exist within, and yet not be observed by another. Which yet the Lord beholds, when He destroys them by the secret look of grace. For it is written, The King Who sitteth in the throne of judgment, scattereth away all evil with His sight.
