Andrew of Caesarea
Some have referred these words to the devastation under Vespasian, taking them in a figurative sense. But we think this speaks of the transition from the period of persecutions to the time of the coming of Antichrist. According to the prophecies, at that time these and similar plagues are to occur. By reflecting on them, men should not deny the punishments brought upon them by Antichrist, which, as we know, have never yet occurred. The earthquake, often mentioned by Scripture, signifies a change of affairs. The expression "Yet once more I will shake" (Hag 2:7) means, as the Apostle says, the alteration of what can be shaken (Heb 12:26-27). In the Old Testament, concerning Israel's march, it is said: "The earth shook, for the heavens dropped" (Ps 67:9). The blackening of the sun and the dark-blood appearance of the moon signify, according to blessed Cyril's explanation, the darkness of soul that overtakes those struck by God's wrath.
