Rev 7:2

“"And I saw another angel ascending from the east, having the seal of the living God" He speaks of Elias the prophet, who is the precursor of the times of Antichrist, for the restoration and establishment of the churches from the great and intolerable persecution. We read that these things are predicted in the opening of the Old and New Testament; for He says by Malachi: "Lo, I will send to you Elias the Tishbite, to turn the hearts of the fathers to the children, according to the time of calling, to recall the Jews to the faith of the people that succeed them." And to that end He shows, as we have said, that the number of those that shall believe, of the Jews and of the nations, is a great multitude which no man was able to number. Moreover, we read in the Gospel that the prayers of the Church are sent from heaven by an angel, and that they are received against wrath, and that the kingdom of Antichrist is cast out and extinguished by holy angels; for He says: "Pray that ye enter not into temptation: for there shall be a great affliction, such as has not been from the beginning of the world; and except the Lord had shortened those days, no flesh should be saved." Therefore He shall send these seven great archangels to smite the kingdom of Antichrist; for He Himself also thus said: "Then the Son of man shall send His messengers; and they shall gather together His elect from the four corners of the wind, from the one end of heaven even to the other end thereof." For, moreover, He previously says by the prophet: "Then shall there be peace for our land, when there shall arise in it seven shepherds and eight attacks of men; and they shall encircle Assur," that is, Antichrist, "in the trench of Nimrod," that is, in the nation of the devil, by the spirit of the Church. Similarly when the keepers of the house shall be moved. Moreover, the Lord Himself, in the parable to the apostles, when the labourers had come to Him and said, "Lord, did not we sow good seed in Thy field? whence, then, hath it tares? answered them, An enemy hath done this. And they said to Him, Lord, wilt Thou, then, that we go and root them up? And He said, Nay, but let both grow together until the harvest; and in the time of the harvest I will say to the reapers, that they gather the tares and make bundles of them, and burn them with fire everlasting, but that they gather the wheat into my barns." The Apocalypse here shows, therefore, that these reapers, and shepherds, and labourers, are the angels. And the trumpet is the word of power. And although the same thing recurs in the phials, still it is not said as if it occurred twice, but because what is decreed by the Lord to happen shall be once for all; for this cause it is said twice. What, therefore, He said too little in the trumpets, is here found in the phials. We must not regard the order of what is said, because frequently the Holy Spirit, when He has traversed even to the end of the last times, returns again to the same times, and fills up what He had before failed to say. Nor must we look for order in the Apocalypse; but we must follow the meaning of those things which are prophesied. Therefore in the trumpets and phials is signified either the desolation of the plagues that are sent upon the earth, or the madness of Antichrist himself, or the cutting off of the peoples, or the diversity of the plagues, or the hope in the kingdom of the saints, or the ruin of states, or the great overthrow of Babylon, that is, the Roman state.”

“This was revealed long ago to Ezekiel concerning him who was clothed in a fine linen robe and who sealed the foreheads of those who mourned so that the righteous would not be destroyed along with the wicked, since the virtue of the saints is hidden and is unknown even to the angels. This is shown also here to the blessed [John], that a preeminent holy power encourages the avenging holy angels to do nothing until they might recognize the servants of the truth by virtue of their having been sealed. Although this has happened partially long ago when those who believed in Christ fled from the siege of Jerusalem by the Romans into very many destinations, the great James having showed to blessed Paul their great number, then, as has been said, this will especially occur at the coming of the antichrist when the seal of the life-giving cross will separate from the faithless the faithful who bear without shame and with boldness the sign of Christ before the impious. Therefore, the angel says, "Do not harm the earth of the sea or the trees, until we have sealed the servants of our God upon their foreheads." Just as the creation, created for our sakes, shares in the torments with us who are being chastised, so too it will be made clean with the saints who are being glorified. Through these words we learn that the virtuous will require the power of angelic assistance before the arrival of the trials which come because of the seal of the Spirit which is given to us. [We learn further] that this seal will reveal its power to that extent that we add our own work to it, for everything remains without aid which by its own will wills not to be aided.”

“And I saw another angel ascending from the east, etc. The Lord born in the flesh, who is the angel of great counsel, the messenger of the Father's will, visited us as the rising sun from on high (Luke 1), bringing the banner of the cross to mark the foreheads of His own.”

“And he cried out with a loud voice to the four angels. The great voice of the Lord is the sublime preaching: Repent, for the kingdom of heaven is at hand.”

“And I saw another angel ascending from the rising of the sun, having the sign of the living God; and he cried with a loud voice to the four angels, to whom it was given to hurt the earth and the sea, saying: Hurt not the earth, nor the sea, nor the trees, till we sign the servants of our God in their foreheads. Christ is an angel because we know he announced the joys of the new life to the world, he about whom it is said, angel of great counsel. [Is. 9:6 acc. to LXX, where the verse is number 5.] The ascent from the rising of the sun meant here is the one by which, starting from the Resurrection itself, which sprang up like a new sun, he grew and filled up the whole world, and illuminated it with the evangelical teaching. With that voice he also prevented the noxious power of the four angels from doing harm, and destroyed it in both initiators and subordinates at the same time; whence Nebuchadnezzar also saw a stone cut out of a mountain without hands strike the aforesaid statue on its iron feet and break it in pieces. [Dan. 2:34] By this stone is represented the Lord Jesus Christ, begotten of Jewish stock without conjugal act, who struck the statue on the feet and made it fall, because he reached the extremity of the kingdom of the Romans with the preaching of the Word, and converted the aforesaid kingdoms of the world to rebuild them wholesomely. This same Mediator is said to have the sign of the living God, that is the mystery of the cross. By the fact that he says not "till I sign" but till we sign, he shows that there are in him many people through whom that mystery is being fulfilled. When he says in their foreheads, he indicates the inner forehead, for we smear both side posts with the blood of the Lamb, [Ref. to Ex. 12:5 et seq.] and it is no use for anyone to wear it on the outside if they do not also receive it on the inside, because faith without works is idle. [James 2:20 acc. to the Greek version.]”

“The day of the formation of man, the time of the prophetical voice, and the time of the clear doctrine, in which the prophesized life would come: for it was necessary that in this time there come a single order, that is, a prophetical disposition similar to the order of Jesus Christ, and of which the head would be an "angel ascending from the rising of the sun, having the seal of the living God," and conforming to Christ.”

“And it is certain that one of them wanted to exterminate the Church. But an "angel ascending from the rising of the sun cried to the four angels: 'Do not harm the earth or the sea till we have sealed the servants of our God on their foreheads.'" Wherefore the Church's tribulations are lasting until now.”

“How can this be? See what is said toward the end of the Apocalypse. Toward the middle, it is said: "I saw the Lamb standing upon Mount Sion, and with Him a hundred and forty-four thousand having His name and the name of His Father written on their foreheads." But at the opening of the sixth seal, it is said in the Apocalypse: "And I saw another angel ascending from the rising of the sun, having the seal of the living God; and he cried with a loud voice to the four angels, who had it in their power to harm the earth and the sea, saying, 'Do not harm the earth or the sea or the trees, till we have sealed the servants of our God on their foreheads.' And I heard the number of those who were sealed, out of every tribe of the children of Israel; of the tribe of Juda, twelve thousand sealed," etc. The tribe of Dan is not counted, but Manasses is counted instead of Dan, and Joseph instead of Ephraim. In Deuteronomy, Simeon is omitted. This is how the contemplative soul is sealed by God. Hence, in reference to the sixth angel, it is said that an angel appeared, "having the seal of the living God." That was when Jerusalem was shown as standing in heaven. And to this angel appeared an expressive seal, as regards the manner of living in conformity with this seal, which is what was sealed: "Of the tribe of Juda, twelve thousand sealed," etc. And that is, that everyone who possesses this thrice-uplifting light must have a threefold perfection corresponding to love. Hence, to seal in this manner is to bind [oneself] to this through a promise and to impress a seal that would correspond to this seal of love.”

“"Then I saw another angel ascending from the east, having the seal of the living God, and he cried out with a loud voice to the four angels to whom it was granted to harm the earth and the sea, saying, 'Do not harm the earth or the sea or the trees until the servants of our God have been sealed.'" The divine angel is said to come from the east, where the sun rises, but not from the west or the evening, symbolizing announcing of the Gospel and promises of blessings.”
