Tabooing vague terms is a key rationality technique. If you want to write an article about spirituality on LW, I think you should start with tabooing the term and explaing what you mean. Once you have done so, I'm fine with you continuing to use the word.

Without going through that exercise there a huge danger of being to vague to be wrong.

Heck, lisper acknowledges it's not the perfect term, and is open to suggestions for better ones.

The problem is not that it's the wrong term but that the article doesn't spend effort into trying to clarify what it means with the term.

Given that he says that he means "social cohesion" with the term later in this thread, it seems to me like he's not clear what he means with it himself.

What does it meant to have a feeling of sacredness?

I haven't spoken about a feeling of sacredness but wanted to refer to sacred values. I mean what the decision science literature means with the term. It operationalized the term. See Emerging sacred values: Iran’s nuclear program if you want to know more.
