What are you saying here? Are you saying that spirituality should be concrete and precise in its definitions, and that doing that opens you more to the personal somehow? That's sounds very strange to me. Can you explain, if that's what you mean?
I feel understanding spirituality in a more concrete way instead of abstract helps to a seeker determine what he believes or don't without the flowery language.
If you told me that jesus is the eucharist and the eucharist is the summit of all christ love for believers, I'd look at you (and the priest, as I did) funny. It's taking a concrete teaching and making it mystical when it doesn't need to be.
People debate all day because of the "Eucharistic" mystery and don't look at it in a more concrete way. When you simplify it, it's easier to understand the spiritual significance of it, and for me personally, gave me a noun to the adjective describing it.
Translation of the above in basic terms is the Eucharist is the sacrificial meal that joins believers in Christ's death (sacrifice of sins), life (mass and Christian deeds), and resurrection (union with god). It just brings people together in worship and the center of that worship, the church, the eucharist this christ.
When it's more concrete it's easier (for me) to say, I believe this because I have understanding of it. When i leave it as a eucharist mystery, we can use word salad all we want but it just ends with being convinces of our own interpretation.
It is also too vague that you can't debate anything. Make it more concrete and simplify it. Draw your own conclusions and express your experiences. A seeker can better judge what he believes without depending on flowery language of the spirit to "blurify" his doubt.
