Rev 8:1

“"And when He had opened the seventh seal, there was silence in heaven for about half an hour." Whereby is signified the beginning of everlasting rest; but it is described as partial, because the silence being interrupted, he repeats it in order. For if the silence had continued, here would be an end of his narrative.”

“"In heaven" means in the church. The silence for half an hour shows the beginning of the eternal rest.”

“Often the number of seven is taken by this saint to correspond to this age and the sabbath rest of the saints. Therefore, also here at the loosing of the seventh seal, the dissolution of the earthly city is signified, the seven angels administering the torments against those people who are deserving of chastisement or punishment. The "silence" reveals the good order of the piety of the angels as well as the fact that the second coming of Christ is unknown even to angels. The "half hour" shows the shortness of time, for when the plagues come and the events of the consummation upon the earth are occurring, the kingdom of Christ will appear.”

“And when he had opened the seventh seal, etc. After the destruction of the Antichrist, a brief rest is believed to come in the Church, about which Daniel predicted thus: "Blessed is he who waits and comes to the thousand three hundred and thirty-five days" (Daniel XII). Which blessed Jerome explains thus: "Blessed," he says, "is he who, after the Antichrist is killed, awaits beyond the one thousand two hundred and ninety days, that is, three and a half years, forty-five days, during which the Lord and Savior is to come in his majesty." But why there is a silence of forty-five days after the killing of the Antichrist is known to divine knowledge. Unless we might say: the delay of the kingdom of the saints is a test of patience. Note that in the sixth seal he sees the greatest pressures on the Church, in the seventh he sees rest, because the Lord, crucified on the sixth day, rested on the Sabbath, waiting for the time of resurrection. Thus far about the opening of the sealed book and the six seals. Now he recapitulates from the beginning, intending to speak the same things differently.”

“And when he had opened the seventh seal, there was silence in heaven, as it were for half an hour. Heaven, as we have often said, means the Church, which produces, as it were, silence for God when, through some of its members, it departs from the abundance of material things to seek the retreat of inner contemplation; but because this silence cannot be perfect in this life, it is said to have lasted as it were for half an hour. Note also that he ended the recapitulation where he said, After this I saw a great multitude, [Rev. 7:9] and now he concludes the narration with the seventh seal.”

“Perhaps someone who is very meticulous might analyze what has been said and say to me: Oh you, what are you doing? Have you perhaps forgotten what was said in the prologues of this Revelation? For it was also said that the first voice I heard was like a trumpet speaking with me, saying, "Come up here, and I will show you what must take place after these things." (Rev. 4:1) And you have become a narrator to us of things not yet come to pass but already happened, recounting the birth of the Lord, the temptation, the teachings and divine signs, the lashes and bonds and the wounds inflicted by Pilate, the cross and the death, and the resurrection and the ascent, or rather, the return to Heaven. To this I would say: most certainly you have heard, my friend, and some of the things that will happen, whenever we recount the righteous among the nations together with Israel around the divine throne, and those who exist with the Lord. And now you also hear in the breaking of the seventh seal. For the one who said to the evangelist, "Come up here, and I will show you what must take place after these things," (Rev. 4:1) did not remove from him the ability to see anything that had happened before, but along with those, he also revealed what was to come. Therefore, listen. The breaking of the seventh seal has accomplished for us the most perfect glory; for no longer is the release from sins and the turning back to God and from God to us as before, but rather the indescribable blessings: to be called children of God, "heirs of God, and joint heirs with Christ," (Rom. 8:17) brothers and friends and children of Christ, to reign with Him (2 Tim. 2:12) and to be glorified together, (Rom. 8:17) and "what no eye has seen, nor ear heard, nor has entered into the heart of man, these good things." (1 Cor. 2:9) What then is the breaking of the seventh seal? It is the second coming of the Lord and the restoration of all good things. For although some are delivered to punishment for their sins, the purpose of Christ and the foundation of the Incarnation is that all become heirs of His kingdom. Therefore, when the seventh seal was broken, it is said that there was silence for about half an hour, as the King of creation was about to come, and all angelic and supernatural powers were overwhelmed by the surpassing glory of the One arriving, and for this reason, there was silence.”
