Someone in the comment box, using the nick "Kepha," pointed out that the Catechism of the Catholic Church actually has a section on this. I reproduce the section below:
II. THE NAME, TITLES, AND SYMBOLS OF THE HOLY SPIRITCute, eh? "Gift" doesn't even make the list of titles. Moreover, as another of the commenters noted, "personified donation" does sound rather modalistic.
The proper name of the Holy Spirit
691 "Holy Spirit" is the proper name of the one whom we adore and glorify with the Father and the Son. The Church has received this name from the Lord and professes it in the Baptism of her new children.16
The term "Spirit" translates the Hebrew word ruah, which, in its primary sense, means breath, air, wind. Jesus indeed uses the sensory image of the wind to suggest to Nicodemus the transcendent newness of him who is personally God's breath, the divine Spirit.17 On the other hand, "Spirit" and "Holy" are divine attributes common to the three divine persons. By joining the two terms, Scripture, liturgy, and theological language designate the inexpressible person of the Holy Spirit, without any possible equivocation with other uses of the terms "spirit" and "holy."
Titles of the Holy Spirit
692 When he proclaims and promises the coming of the Holy Spirit, Jesus calls him the "Paraclete," literally, "he who is called to one's side," ad-vocatus.18 "Paraclete" is commonly translated by "consoler," and Jesus is the first consoler.19 The Lord also called the Holy Spirit "the Spirit of truth."20
693 Besides the proper name of "Holy Spirit," which is most frequently used in the Acts of the Apostles and in the Epistles, we also find in St. Paul the titles: the Spirit of the promise,21 the Spirit of adoption,22 the Spirit of Christ,23 the Spirit of the Lord,24 and the Spirit of God25 - and, in St. Peter, the Spirit of glory.26
Taylor quotes Aquinas and Augustine. Whether he understands them is a point I won't explore. Nevertheless, whether or not they agree with the point he's trying to make, shouldn't the CCC trump anything that the fathers or schoolmen have to save about the subject?
