Holy in the sense of something appealing to venerate and worship? No. Holy in the sense of something fascinating and frankly awe-inspiring in its mechanism and importance to life? Yes.
These are the definitons I got for “Holy”:
Dictionary:
dedicated or consecrated to God or a religious purpose; sacred: the Holy Bible | the holy month of Ramadan.
• (of a person) devoted to the service of God: saints and holy men.
• morally and spiritually excellent: I do not lead a holy life.
Again Holy means something that is “set apart”. You may be awed by something, you may find it fascinating, you may like it, or even cherish it. But that does not make that thing “holy”. Cherished, liked, awe-inspiring- sure. But not holy. I am afraid that that word does not apply the way you would like it to.
You consider it a misunderstanding or a distortion because you are combining “spirituality” in the sense of supernaturalism with “spirituality” as the senses of awe, wonder, respect, and gratitude when we consider the universe and our lives. The point of the book is to tease apart those two ideas.
I am also awed by the complexity, versatility and beauty of matter. This is why I greatly enjoy science (without the scientism). But God is not “ghost in the machine”. God is the intentional designer, engineer, programmer and creator of the machine, which is far more than a mere machine as we can conceive of a machine.
You seem to be arguing that somehow venerating/adoring/worshiping matter is all that is needed for spirituality and you may be implying that it is somehow superior to worshiping God, the creator. But you’re not quite getting that in worshiping God, we are indeed in awe and eternally grateful for his works.
God made the world. And it was good. Matter is good. In fact, we Catholics expect to be reunited with our material (though glorified) bodies someday, not just be disembodied spirits. I love nature and the science that attempts to discover how it works. But ultimately, a work without a creator and without a purpose is devoid of true holiness and spirituality. You may well try to deny this- say that nature without an author is enough. But it is not. The human spirit longs for more.
I’ve walked down this road before. I, like you, tried to tell myself that nature and my connection to the cosmos was enough. It certainly is poetic and awe-inspiring. But it is not enough. It is just a piece of the puzzle, a means towards an end, not the whole picture and not an end in itself.
Awe, wonder, respect, and gratitude are just that. But they are not spirituality. There needs to be a spirit for spirituality. This is the definition I got for Spirituality:
Dictionary:
“1 of, relating to, or affecting the human spirit or soul as opposed to material or physical things: I’m responsible for his spiritual welfare | the spiritual values of life.
• (of a person) not concerned with material values or pursuits.
2 of or relating to religion or religious belief: the tribe’s spiritual leader.”
What you are alluding to ultimately are subjective thoughts and emotions, not spirituality. I have those thoughts and emotions too. And they are good. But they are not, in themselves, equivalent to spirituality. Spirituality is, by definition, rooted or reaching beyond the material world.
