http://en.wikipedia.org/wiki/Trinity:
In Freemasonry the Holy Spirit is not actually a person, but a manifestation of Hebrew philosophy and the Holy Spirit is considered a "type of universal agent." (Albert Pike, Morals and Dogma, pgs. 552, 734). However, the Bible teaches that the Holy Spirit is a divine person. The Bible teaches that He is complete and unchanging. The word Trinity is not found in the Bible but it explains what the biblical concept of the Trinity is. The Trinity is from everlasting to everlasting; that is, the Holy Trinity is real.
