[Harry Potter] Why exactly is Voldemort afraid of Dumbledore?

Throughout the series Dumbledore is explicitly said to be the only Voldemort fears. Why exactly is there fear? I get that even his most strident detractors will generally acknowledge that Dumbledore is one of the greatest and most powerful wizards of all time and that he’s at least worthy of respect. And in the limited interactions we see of Tom and Dumbledore prior to Tom’s first fall it seems that Dumbledore is always one step ahead of Tom and knows more about his true intentions and character than Tom would like to be seen, but why is that Dumbledore is the only one Voldemort FEARS instead of respects or considers to be on his level? I could see Voldemort maybe being a little anxious of him since Dumbledore seems to be aware of the horcruxes Tom had made and that should Dumbledore identify and find all of them he would be able to defeat Voldemort for good but unless I’m mistaken, it’s not until pretty deep into the seventh book that Voldemort realizes the horcruxes are being hunted and some had already been destroyed. So what exactly is it that made Voldemort fearful of Dumbledore? Is it just Dumbledore’s immense wizarding power?

I think you answered your own question in your analysis.  Dumbledore is powerful and Voldemort fears anything more powerful than him.  You have to keep in mind that Voldemort was in constant terror of death.   He wasn't brave, no matter how cocky he acted.  He feared death more than most people, and Dumbledore was one of the few beings that could absolutely kill him if necessary.  Indeed, he pretty much did kill Voldemort through his influence on Harry Potter.  It was a very specific situation that required Harry in order to put Voldemort down for good, so Dumbledore couldn't do it single-handedly, but he was the prime mover.
