National Geographic had an article about sea monsters. There is a fossil record to show that they did exist, as National Geographic rightly says, but then they pervert the issue by using a vastly inaccurate time line (i.e. millions of years, of which there is no such thing) and invoking evolution, which is also false. They also point out that many of the ancient drawings of sea monsters almost exactly fit the fossil record. What about dragons, which are also contained in the writings of antiquity from all the ends of the earth?
Dragons in the Bible?
Isaias, whose prophecies strikingly foreshadowed Christ's crucifixion about 700 years before the fact, mentions dragons four times. Jeremias mentions them seven times; Micheas and Malachias once each. The books of Deuteronomy, Esther and Psalms all mention dragons. Daniel killed a dragon.
God specifically describes a creature that breathes fire.
The Bible leaves very little room for a hyperbole or metaphor interpretation. A creature called Leviathan (which must be the name given to this creature by Adam - see Genesis 2:20), is described by God to the holy Job. The following is part of this description in the book of Job, wherein God describes the magnificence of His Creation:
While it is true that not every book of Scripture is intended as a literal descriptive account, there is nothing in the book of Job to suggest that it is anything but this. The book is an empirical recounting of the creation. Thus we should conclude that there are (or at least were) indeed creatures created by God which were capable of breathing fire.
Is this so hard to believe? We know that biological organisms can produce various flammable substances, whether gasses such as hydrogen and methane, or liquids (oils, alcohol) or solids (fats). That's not too much of a problem in terms of possibility. We also know, thanks to the bombadier beetle, that it's possible to have an organic ignition system.
If dragons were real then they could have just been another kind of dinosaur. There is paleontological evidence that a skull arrangement could have accommodated fire breathing. For example, the hadrosaurs’ nasal cavities could easily have connected to chemical reserves in the hollow, horny crest. Many other dinosaurs had similar cavities in their skulls which could accommodate such chemical reserves.
Stories about Catholic Saints mention dragons and similar creatures
Most are aware of the story of St. George and his slaying of a dragon. But fewer, perhaps, are aware of other encounters between saints and creatures believed by the secular world to be either impossible or extinct.
Scripture uses real animals to figure the devil
Genesis 3:13: "And the Lord God said to the woman: Why hast thou done this? And she answered: The serpent deceived me, and I did eat."
1st St. Peter 5:8: "Be sober and watch: because your adversary the devil, as a roaring lion, goeth about seeking whom he may devour."
Nobody disputes the existence of either serpents or lions.
Apocalypse 20:2: "And he laid hold on the dragon the old serpent, which is the devil and Satan, and bound him for a thousand years."
Why then, should we assume that God has broken from His consistent manner of speaking, whereby He uses the creatures of this world as figures of spiritual things?
Scripture mentions other "impossible" creatures alongside real animals
Psalm 90:13: "Thou shalt walk upon the asp and the basilisk: and thou shalt trample under foot the lion and the dragon."
Do we accuse God Himself of inconsistency, intermixing mythological creatures and real creatures in the same inspired saying of the Prophet?
Psalm 91:11: "But my horn shall be exalted like that of the unicorn: and my old age in plentiful mercy."
What should we believe?
Dragons were used as a figure in many prophecies and visions in the Scriptures. We should believe what the evidence proposes as being true and in the light of evidence from the modern disciplines of biology and paleontology, denying the (at least previous) existence of dragons, as they have been described in the Bible and in the "legends" of every nation would be on the same level as denying the existence of magic and wizards, which are also specifically mentioned (and condemned) in the Bible, and which also are a recognized reality in Catholic tradition and are mentioned by Catholics saints. Although it has never been considered heresy (to my knowledge) to not believe in the existence of dragons, I, for one, am not about to make such a denial.
As to the question: "Where are they now?"
