Yet I am also the official*, since all things living blaze from me; and I am equally life in eternity, which is neither begun, nor will end; and at the same time God is life moving [itself] and working, and yet this life is one in three powers. Eternity is therefore the Father, the Word is the Son; the breath connecting these two is called Holy Spirit, as also God left His mark in man, in whom are body, soul and intellect.
(* Official could be understood as servant or attendant:
It comes from the Old French official (12th century), from the Latin officialis ("attendant to a magistrate, public official"), the noun use of the original adjective officialis ("of or belonging to duty, service, or office") from officium("office"). - http://en.wikipedia.org/wiki/Official)
Sed et officialis sum, quoniam omnia vitalia de me ardent; et aequalis vita in aeternitate sum, quae nec orta est, nec finietur, eademque vita se movens et operans Deus est, et tamen haec vita una in tribus viribus est. Aeternitas itaque Pater, Verbum Filius; spiramen haec duo connectens Spiritus sanctus dicitur, sicut etiam Deus in homine, in quo corpus, anima et rationalitas sunt, signavit.
This passage is fairly straight forward. St. Hildegard invites us to contemplate our experience of life in the natural world and perceive as it were the echo of the life of God. The same life that ignited life in creatures is eternal, without beginning or end. The limits we experience to life do not reflect the life of the Source.
Life without beginning or end is contrasted with life that moves and works - Eternal life is contrasted with the life of Creation. These two, are in fact one in three powers (or forces). Eternal life and created life are drawn together, as it were, by the life of the Spirit - the breath that connects the two. See also St. Augustine (De Trinitate VI, 10) and St. Hilary (De Trinitate II) for a similar reflection
The final phrase sees within man this Trinitarian mark of life: body, soul, and spirit. The life of the body is movement and work, the life of the spirit is contemplation - Eternal life, life without beginning or end -, and the life that unites the two: the soul - invisible, immaterial like spirit, and like breath, more essential to the body than food or drink. Saint Augustine pushes the analogy further by looking into the very spirit of man for a created trinity - see the last chapter of De Trinitate if you're interested.
