Harmony is a mathematical concept. The Greeks certainly appreciated it on "paper". You likely have them to thank for it being a living relic in your current religious views that are highly influenced by geometric ideas and arithmetic. What we have in the real world are things that are only closely approximating ideal relationships. An example of that is our musical notation formalism, which is not perfect, but close enough for our ears to be called that.
All these beautiful things that apparently reflect the golden mean in their construction (shells, i.e.) don't actually do that when you look at them closely. They are only near enough, sometimes not even that close, to lead people to bad conclusions about perfect design and intent.
Funnier, huge arguments over the exact base angle of the Great Pyramid have for long preoccupied some people who want that physical symbol to reflect something perfect that they demand be there to echo their idea of divine perfection. No matter where you look in the real world you find large scale phenomena guided by chaotic processes that end up mimicking something that looks rather well planned. It's a huge problem when it come to those who see only with the eyes of of child.
If we exist at all it is because of a fundamental asymmetry and the falling apart of higher dimensional super symmetry at some asymmetry engendering fork in the road. If you want to call perfection God you have his counterpart to thank for your existence. It's a rather poor way of describing your status in a story, though. I don't think you need to look at yourself as having fallen from perfection. Best to accept one's imperfections as a reflection of an imperfect state of affairs that allows everything.
You claim to like Francis Bacon. Bacon would tell you your religion is a poor attempt at a Utopian story for a given time. He knew a thing or two about it, having watched the Tudors tweak it as they desired for their own interests. What is closest to the truth is what came first as an inspired story, according to him. And what came first is not what has come after that has evolved from it. Amen indeed. Sun God. Giver of light. Illuminator. Great ideas borrowed over and over...
