From the Fourth Chapter
8 “Six wings.” These are the testimonies of the books of the Old Testament. Thus, twenty and four make as many as there are elders sitting upon the thrones. But as an animal cannot fly unless it have wings, so, too, the announcement of the New Testament gains no faith unless it have the fore-announced testimonies of the Old Testament, by which it is lifted from the earth, and flies. For in every case, what has been told before, and is afterwards found to have happened, that begets an undoubting faith. Again, also, if wings be not attached to the living creatures, they have nothing whence they may draw their life. For unless what the prophets foretold had been consummated in Christ, their preaching was vain. For the Catholic Church holds those things which were both before predicted and afterwards accomplished. And it flies, because the living animal is reasonably lifted up from the earth. But to heretics who do not avail themselves of the prophetic testimony, to them also there are present living creatures; but they do not fly, because they are of the earth. And to the Jews who do not receive the announcement of the New Testament there are present wings; but they do not fly, that is, they bring a vain prophesying to men, not adjusting facts to their words. And the books of the Old Testament that are received are twenty-four, which you will find in the epitomes of Theodore. But, moreover (as we have said), four and twenty elders, patriarchs and apostles, are to judge His people. For to the apostles, when they asked, saying, “We have forsaken all that we had, and followed You: what shall we have?” our Lord replied, “When the Son of man shall sit upon the throne of His glory, you also shall sit upon twelve thrones, judging the twelve tribes of Israel.” But of the fathers also who should judge, says the patriarch Jacob, “Dan also himself shall judge his people among his brethren, even as one of the tribes in Israel.”
5. “And from the throne proceeded lightnings, and voices, and thunders, and seven torches of fire burning.” And the lightnings, and voices, and thunders proceeding from the throne of God, and the seven torches of fire burning, signify announcements, and promises of adoption, and threatenings. For lightnings signify the Lord's advent, and the voices the announcements of the New Testament, and the thunders, that the words are from heaven. The burning torches of fire signify the gift of the Holy Spirit, that it is given by the wood of the passion. And when these things were doing, he says that all the elders fell down and adored the Lord; while the living creatures— that is, of course, the actions recorded in the Gospels and the teaching of the Lord— gave Him glory and honour. In that they had fulfilled the word that had been previously foretold by them, they worthily and with reason exult, feeling that they have ministered the mysteries and the word of the Lord. Finally, also, because He had come who should remove death, and who alone was worthy to take the crown of immortality, all for the glory of His most excellent doing had crowns.
10. “And they cast their crowns under His feet.” That is, on account of the eminent glory of Christ's victory, they cast all their victories under His feet. This is what in the Gospel the Holy Spirit consummated by showing, For when about finally to suffer, our Lord had come to Jerusalem, and the people had gone forth to meet Him, some strewed the road with palm branches cut down, others threw down their garments, doubtless these were setting forth two peoples— the one of the patriarchs, the other of the prophets; that is to say, of the great men who had any kind of palms of their victories against sin, and cast them under the feet of Christ, the victor of all. And the palm and the crown signify the same things, and these are not given save to the victor.
