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 14.3
On the City of God Against the PagansBut if any one says that the flesh is the cause of all vices and ill conduct, inasmuch as the soul lives wickedly only because it is moved by the flesh, it is certain he has not carefully considered the whole nature of man. For the corruptible body, indeed, weighs down the soul. Whence, too, the apostle, speaking of this corruptible body, of which he had shortly before said, though our outward man perish, says, We know that if our earthly house of this tabernacle were dissolved, we have a building of God, a house not made with hands, eternal in the heavens. For in this we groan, earnestly desiring to be clothed upon with our house which is from heaven: if so be that being clothed we shall not be found naked. For we that are in this tabernacle do groan, being burdened: not for that we would be unclothed, but clothed upon, that mortality might be swallowed up in life.
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 ..."
