Right, but calling it a paradox is a model of it's own. It's not remaining neutral on the mystery of God. Calling it a paradox is saying there is no mystery, it's saying that it is undeniably illogical, unreasonable, self refuting, and inconsistent. That sounds like a hazard to me. Wouldn't you feel safer just calling it incomprehensible instead of a logical paradox? Besides, The Trinity being 3 persons and 1 substance doesn't even fall into the category of paradox, they are not mutually exclusive concepts.
