Master, Ruler
Like many words, "master" and "ruler" obtain a range of objects. The God who created us is called Master, and yet petty owners of human slaves are called masters. God is Ruler of the universe, and also local governors are called rulers.
Jesus was called "sir," and "master," and "lord" in more mundane senses, especially by those who did not know Him. But for Jude son of Joseph, a monotheist Jew and Jesus's own half-brother, to call Jesus our "only Master and Lord" was a stunning claim. To further claim that He existed with the ancient Israelites frustrates every alternative interpretation: Jude was saying that Jesus is Yahweh. He even said everyone knew it already (εἰδότας πάντα).
