nds to works, according to Gal. 5:6:
"Faith . . . worketh by charity."

The consequence is that the gift of knowledge also, primarily and
principally indeed, regards speculation, in so far as man knows what
he ought to hold by faith; yet, secondarily, it extends to works,
since we are directed in our actions by the knowledge of matters of
faith, and of conclusions drawn therefrom.

Reply Obj. 1: Augustine is speaking of the gift of knowledge, in so
far as it extends to works; for action is ascribed to knowledge, yet
not action solely, nor primarily: and in this way it directs piety.

Hence the Reply to the Second Objection is clear.

Reply Obj. 3: As we have already stated (Q. 8, A. 5) about the gift
of understanding, not everyone who understands, has the gift of
understanding, but only he that understands through a habit of grace:
and so we must take note, with regard to the gift of knowledge, that
they alone have the gift of knowledge, who judge aright about matters
of faith and action, through the grace bestowed on them, so as never
to wander from the straight path of justice. This is the knowledge of
holy things, according to Wis. 10:10: "She conducted the just . . .
through the right ways . . . and gave him the knowledge of holy
things."

FOURTH ARTICLE [II-II, Q. 9, Art. 4]

Whether the Third Beatitude, "Blessed Are They That Mourn," etc.
Corresponds to the Gift of Knowledge?

Objection 1: It would seem that the third beatitude, "Blessed are they
that mourn," does not correspond to the gift of knowledge. For, even
as evil is the cause of sorrow and grief, so is good the cause of joy.
Now knowledge brings good to light rather than evil, since the latter
is known through evil: for "the straight line rules both itself and
the crooked line" (De Anima i, 5). Therefore the aforesaid beatitude
does not suitably correspond to the gift of knowledge.

Obj. 2: Further, consideration of truth is an act of knowledge. Now
there is no sorrow in the consideration of truth; rather is there
joy, since it is written (Wis. 8:16): "Her conversation hath no
bitterness, nor her company any tediousness, but joy and gladness."
Therefore the aforesaid beatitude does not suitably correspond with
the gift of knowledge.

Obj. 3: Further, the gift of knowledge consists in speculation,
before operation. Now, in so far as it consists in speculation,
sorrow does not correspond to it, since "the speculative inte
