to the Holy Ghost (Q. 38, A. 2). He also
designates three appropriated terms. For he appropriates "eternity"
to the Father, species to the Son, and "use" to the Holy Ghost.
This he does apparently without reason. For "eternity" imports
duration of existence; species, the principle of existence; and
'use' belongs to the operation. But essence and operation are not
found to be appropriated to any person. Therefore the above terms are
not fittingly appropriated to the persons.

Obj. 2: Further, Augustine says (De Doctr. Christ. i, 5): "Unity is
in the Father, equality in the Son, and in the Holy Ghost is the
concord of equality and unity." This does not, however, seem fitting;
because one person does not receive formal denomination from what is
appropriated to another. For the Father is not wise by the wisdom
begotten, as above explained (Q. 37, A. 2, ad 1). But, as he
subjoins, "All these three are one by the Father; all are equal by
the Son, and all united by the Holy Ghost." The above, therefore, are
not fittingly appropriated to the Persons.

Obj. 3: Further, according to Augustine, to the Father is attributed
"power," to the Son "wisdom," to the Holy Ghost "goodness." Nor does
this seem fitting; for "strength" is part of power, whereas strength
is found to be appropriated to the Son, according to the text,
"Christ the strength [*Douay: power] of God" (1 Cor. 1:24). So it is
likewise appropriated to the Holy Ghost, according to the words,
"strength [*Douay: virtue] came out from Him and healed all" (Luke
6:19). Therefore power should not be appropriated to the Father.

Obj. 4: Likewise Augustine says (De Trin. vi, 10): "What the Apostle
says, "From Him, and by Him, and in Him," is not to be taken in a
confused sense." And (Contra Maxim. ii) "'from Him' refers to the
Father, 'by Him' to the Son, 'in Him' to the Holy Ghost." This,
however, seems to be incorrectly said; for the words "in Him" seem to
imply the relation of final cause, which is first among the causes.
Therefore this relation of cause should be appropriated to the
Father, Who is "the principle from no principle."

Obj. 5: Likewise, Truth is appropriated to the Son, according to John
14:6, "I am the Way, the Truth, and the Life"; and likewise "the book
of life," according to Ps. 39:9, "In the beginning of the book it is
written of Me," where a gloss observes, "that is, with the Father Who
is My head," also this word "Who is"; because on the text of Isai
