And I'm regularly amused by people who fear the word "consubstantial".  Goodness.  Whether or not the word, at the time, was the best translation of the Greek is inconsequential to the meaning the, then, neologism took on; it is, now, the translation of the homoousios incontrovertibly.
I'm not saying that there cannot be other words to express the meaning, in English, if you'd do the courtesy of reading my posts; only that "one in being" is deficient.
