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

A: On the contrary,
Augustine says (De Serm. Dom. in Monte iv): "Knowledge befits the mourner, who has discovered that he has been mastered by the evil which he coveted as though it were good."

I answer that,
Right judgment about creatures belongs properly to knowledge. Now it is through creatures that man's aversion from God is occasioned, according to Wis. 14:11: "Creatures . . . are turned to an abomination . . . and a snare to the feet of the unwise," of those, namely, who do not judge aright about creatures, since they deem the perfect good to consist in them. Hence they sin by placing their last end in them, and lose the true good. It is by forming a right judgment of creatures that man becomes aware of the loss (of which they may be the occasion), which judgment he exercises through the gift of knowledge.

Hence the beatitude of sorrow is said to correspond to the gift of knowledge.

Reply Obj. 1: Created goods do not cause spiritual joy, except in so far as they are referred to the Divine good, which is the proper cause of spiritual joy. Hence spiritual peace and the resulting joy correspond directly to the gift of wisdom: but to the gift of knowledge there corresponds, in the first place, sorrow for past errors, and, in consequence, consolation, since, by his right judgment, man directs creatures to the Divine good. For this reason sorrow is set forth in this beatitude, as the merit, and the resulting consolation, as the reward; which is begun in this life, and is perfected in the life to come.

Reply Obj. 2: Man rejoices in the very consideration of truth; yet he may sometimes grieve for the thing, the truth of which he considers: it is thus that sorrow is ascribed to knowledge.

Reply Obj. 3: No beatitude corresponds to knowledge, in so far as it consists in speculation, because man's beatitude consists, not in considering creatures, but in contemplating God. But man's beatitude does consist somewhat in the right use of creatures, and in well-ordered love of them: and this I say with regard to the beatitude of a wayfarer. Hence beatitude relating to contemplation is not ascribed to knowledge, but to understanding and wisdom, which are about Divine things.

QUESTION 10

OF UNBELIEF IN GENERAL (In Twelve Articles)

In due sequence we must consider the contrary vices: first, unbelief, which is contrary to faith; secondly, blasphemy, which is opposed to confession of faith; thirdly, ignorance and dulness of mind, which are contrary to knowledge and understanding.

As to the first, we must consider (1) unbelief in general; (2) heresy; (3) apostasy from the faith.

Under the first head there are twelve points of inquiry:

(1) Whether unbelief is a sin?

(2) What is its subject?

(3) Whether it is the greatest of sins?

(4) Whether every action of unbelievers is a sin?

(5) Of the species of unbelief;

(6) Of their comparison, one with another;

(7) Whether we ought to dispute about faith with unbelievers?

(8) Whether they ought to be compelled to the faith?

(9) Whether we ought to have communications with them?

(10) Whether unbelievers can have authority over Christians?

(11) Whether the rites of unbelievers should be tolerated?

(12) Whether the children of unbelievers are to be baptized against their parents' will?
