o move and impel the will of
the lover towards the object loved. Further, holiness is attributed
to whatever is ordered to God. Therefore because the divine person
proceeds by way of the love whereby God is loved, that person is most
properly named "The Holy Ghost."

Reply Obj. 1: The expression Holy Spirit, if taken as two words, is
applicable to the whole Trinity: because by 'spirit' the
immateriality of the divine substance is signified; for corporeal
spirit is invisible, and has but little matter; hence we apply this
term to all immaterial and invisible substances. And by adding the
word "holy" we signify the purity of divine goodness. But if Holy
Spirit be taken as one word, it is thus that the expression, in the
usage of the Church, is accommodated to signify one of the three
persons, the one who proceeds by way of love, for the reason above
explained.

Reply Obj. 2: Although this name "Holy Ghost" does not indicate a
relation, still it takes the place of a relative term, inasmuch as it
is accommodated to signify a Person distinct from the others by
relation only. Yet this name may be understood as including a
relation, if we understand the Holy Spirit as being breathed
[spiratus].

Reply Obj. 3: In the name Son we understand that relation only which
is of something from a principle, in regard to that principle: but in
the name "Father" we understand the relation of principle; and
likewise in the name of Spirit inasmuch as it implies a moving power.
But to no creature does it belong to be a principle as regards a
divine person; but rather the reverse. Therefore we can say "our
Father," and "our Spirit"; but we cannot say "our Son."

SECOND ARTICLE [I, Q. 36, Art. 2]

Whether the Holy Ghost Proceeds from the Son?

Objection 1: It would seem that the Holy Ghost does not proceed from
the Son. For as Dionysius says (Div. Nom. i): "We must not dare to say
anything concerning the substantial Divinity except what has been
divinely expressed to us by the sacred oracles." But in the Sacred
Scripture we are not told that the Holy Ghost proceeds from the Son;
but only that He proceeds from the Father, as appears from John 15:26:
"The Spirit of truth, Who proceeds from the Father." Therefore the
Holy Ghost does not proceed from the Son.

Obj. 2: Further, In the creed of the council of Constantinople (Can.
vii) we read: "We believe in the Holy Ghost, the Lord and Life-giver,
who proceeds from
