Wisdom of Solomon 9:15
13 For who can learn the counsel of God? Or who can discern what the Lord wills? 14 For the reasoning of mortals is worthless, and our designs are likely to fail; 15 for a perishable body weighs down the soul, and this earthy tent burdens the thoughtful mind. 16 We can hardly guess at what is on earth, and what is at hand we find with labor; but who has traced out what is in the heavens? 17 Who has learned your counsel, unless you have given wisdom and sent your holy spirit from on high?
Augustine City of God 19.4
On the City of God Against the PagansAnd what shall I say of those who suffer from demoniacal possession? Where is their own intelligence hidden and buried while the malignant spirit is using their body and soul according to his own will? And who is quite sure that no such thing can happen to the wise man in this life? Then, as to the perception of truth, what can we hope for even in this way while in the body, as we read in the true book of Wisdom, The corruptible body weighs down the soul, and the earthly tabernacle presses down the mind that muses upon many things? And eagerness, or desire of action, if this is the right meaning to put upon the Greek ὁρμη, is also reckoned among the primary advantages of nature; and yet is it not this which produces those pitiable movements of the insane, and those actions which we shudder to see, when sense is deceived and reason deranged?
Notes and References
"... In affirming the canonicity of the two ‘Solomonic’ books not written by Solomon, Augustine says of Wisdom and Sirach “the Church especially in the West has accepted them as authoritative from antiquity”; City of God 17.20). A survey of patristic comments on the liturgical use of what Rufinus called the ecclesiastical books bears out Augustine’s geographical distinction. Eastern sources restrict the liturgical use of documents to the books of the Jewish canon. Cyril of Jerusalem (Catechesis 4.36–38) emphatically asserts that only the 22 books accepted by the Jews find a place in Christian liturgy, and he advises catechumens to maintain this standard in their private reading. Athanasius (Festal Letters 39) assigns the ecclesiastical books the role of elementary instruction in the faith, as do the Apostolic Canons (canon 85); this position seems to discount their use in the liturgy. The Council of Laodicea is more explicit; in the same context in which it limits the OT canon to 22 books ... However, the matter stood differently among Latin writers: Jerome, Rufinus, and Augustine all affirm that the ecclesiastical books are used in the corporate worship of the Church ... if the Church reads a ‘scriptural’ book, it is a canonical book. Similarly, Augustine responds to the objection of some that the Book of Wisdom is not canonical by arguing that its employment in the liturgy implies its divine authority ..."
