Sometimes it’s worthwhile to explore the Bible in its original languages. The Hebrew word used for the Holy Spirit in the Old Testament is Ruah. The Greek word used for the Holy Spirit in the New Testament is Pneuma. Both mean Spirit or Breath. So it is quite orthodox to refer to the Holy Spirit as the Breath of God. Now, as one of the titles for Jesus in the New Testament is the Word of God this raises some interesting possibilities for alternative language when speaking of the Trinity: instead of Father, Son, and Holy Spirit, we could say Speaker, Word, and Breath.
