Interestingly enough, I was just reading about the recent trend of using alternate wording in the baptismal rites of certain Roman Catholic churches. It seems that certain North American churches tried to avoid referring to the Trinity with masculine terms.
Tradionally, all baptisms were performed "in the name of the Father, and of the Son, and of the Holy Spirit." In an effort to avoid such "phallocentric" terminology, certain "progressive" elelments within the Church used the phrasing "in the name of the Creator, and of the Redeemer, and of the Sanctifier," or "in the name of the Creator, Liberator, and Sustainer."
When asked if baptisms using such phraseology were valid, the Vatcan's Congregtion for the Doctrine of the Faith responded in the negative - no, such baptisms were invalid. All baptisms using alternate wording would have to be redone.
I think that this point reinforces the point that I made in my earlier post. The only way to apply philosophy to the concept of the Trinity is to study the Trinity as a historical "entity" which has evolved over time.
