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 Confessions 7.17
And I marvelled that I now loved You, and no phantasm instead of You. And yet I did not merit to enjoy my God, but was transported to You by Your beauty, and presently torn away from You by my own weight, sinking with grief into these inferior things. This weight was carnal custom. Yet was there a remembrance of You with me; nor did I any way doubt that there was one to whom I might cleave, but that I was not yet one who could cleave unto You; for that the body which is corrupted presses down the soul, and the earthly dwelling weighs down the mind which thinks upon many things. And most certain I was that Your invisible things from the creation of the world are clearly seen, being understood by the things that are made, even Your eternal power and Godhead.
Notes and References
"... the West, further from the home of the Hebrew canon, and knowing the Old Testament chiefly through the Latin version of the LXX, did not scruple to mingle non-canonical books with the canonical. Hilary and Ruffinus were doubtless checked, the one by the influence of Eastern theologians, the other by the scholarship of Jerome; but Hilary mentions that there were those who wished to raise the number of the canonical books to twenty-four by including Tobit and Judith in the canon. From the end of the fourth century the inclusion of the non-canonical books in Western lists is a matter of course. Even Augustine has no scruples on the subject; he makes the books of the Old Testament forty-four (de doctr. Chr. ii. 13 "his xliv libris Testamenti Veteris terminatur auctoritas"), and among them Tobit, Judith, and two books of Maccabees take rank with the histories; and the two Wisdoms, although he confesses that they were not the work of Solomon, are classed with the Prophets. His judgement was that of his Church ("sunt canonicae scripturae Salomonis libri quinque ... Tobias, Judith ... Machabaeorum libri duo"). The African Church had probably never known any other canon, and its belief prevailed wherever the Latin Bible was read ..."
