What's the difference between 'Divine Providence' and 'Holy Spirit' in this statement? In the 22nd annual meeting of the International Catholic-Jewish Liaison Committee, they released a statement that said:


  Jews and Christians share the heritage of the biblical testimony of God's relationship with the human family throughout history. Our Scriptures bear witness to both individuals and the people as a whole being called, taught, guided and protected by Divine Providence. In light of this sacred history, Catholic and Jewish participants in the meeting responded to emerging opportunities and difficulties facing religious belief and practice in today's world.


Why, in the official statement above, signed by Catholic Church and Jews, is 'Divine Providence' used, and not 'Holy Spirit'?

Perhaps there is an ontological difference between 'Divine Providence' and 'Holy Spirit'? If so, can anyone explain what the difference is?
One Theory: It's possible that the Jews (which Jews? There's not just one body of "orthodox" Jews.) do not wish to endorse the Christian idea of the Trinity. The Holy Spirit is not exactly described as a divine person in the OT. "Spirit" and "Spirit of God" are used, but not really in the same sense as "Holy Spirit" is used in the NT.

Perhaps alluding to the Holy Spirit is not a concession that the Jews wish to make, and for the sake of expressing positive things in common, "Divine Providence" was something both groups could agree on.
