>Caesar's Latin is Vulgate's Latin, which is Newton's Latin, which is the Pope's Latin

Not really. There are significant differences between classical and medieval latin, since during the medieval period Latin was a living language in use by the clergy and educated. The differences wouldn't have been nearly enough to render classical and medieval latin unintelligble to one another of course, but Virgil probably would have scratched his head at some of Thomas Aquinas' grammar.
