The RCs may say they canonized the books of the NT, but that doesn't mean they interpret them correctly, especially the jewish/hebrew book of Revelation, in my most humble view
Exodus 15:1 Then Mosheh and sons of Yisra'el are
singing the song, this to YHVH.
And they are saying to say of "I shall sing to YHVH that to exalt He exalts.
Horse and one riding of him He heaved into sea [Reve 15:3]
Reve 15:3 And
they sing the song of Moses, the bondservant of the God and the Song of the Lamb
saying "great and marvelous the works of Thee
Lord! the God, the Almighty. Just and true the ways of Thee, the King of the saints" [*ages/*nations].
THE SYMBOLISM IN BOOK OF REVELATION
One man studied and found 348 allusions (not illusions, Light) in Revelation from the Old Testament. You see the similarity in wording and the context mirrored in Revelation and the particular Old Testament story, and immediately can recognize the reference source! Thats, IF you know the bible well enough to even notice that.
95 of the 348 plain references used in Revelation as taken from the Old Testament are repeated in Revelation. That makes about 250 Old Testament passages are cited. How many chapters are in Revelation? 22. That makes about TEN OLD TESTAMENT REFERENCES FOR EVERY CHAPTER!
