No the accurate way to refer to God is "God." In English anyhow. I know Arabic Christians refer to God as "Allah." I don't know German or French or other languages.
No Bible I know of, starts the Bible out with "in the beginning, they created the heavens and earth."
Well if the OP article refers to God as "they" then why can't you?
See your Post #2.
1. There are but three Persons in the Godhead, who are infinite in being and perfection, a most pure spirit, invisible, without body, parts, or passions; immutable, immense, eternal, incomprehensible, almighty, most wise, most holy, most free, most absolute; working all things according to the counsel of
their own immutable and most righteous will, for
their own glory; most loving, gracious, merciful, long-suffering, abundant in goodness and truth, forgiving iniquity, transgression, and sin; the rewarder of them that diligently seek
them; and withal, most just, and terrible in
their judgments, hating all sin, and who will by no means clear the guilty.
2. The three Persons in the Godhead hath all life, glory, goodness, blessedness, in and of
themselves; and are alone in and unto
themselves all-sufficient, not standing in need of any creatures which
they hath made, nor deriving any glory from
them, but only manifesting
their own glory in, by, unto, and upon
them.
They are the alone fountain of all being, of whom, through whom, and to whom are all things; and hath most sovereign dominion over
them, to do by
them, for
them, or upon
them whatsoever
they pleaseth. In
their sight all things are open and manifest,
their knowledge is infinite, infallible, and independent upon the creature, so as nothing is to
them contingent, or uncertain.
They are most holy in all
their counsels, in all
their works, and in all
their commands. To
them is due from angels and men, and every other creature, whatsoever worship, service, or obedience they are pleased to require of
them.
