Wisdom of Solomon 1:9
7 Because the spirit of the Lord has filled the world, and that which holds all things together knows what is said, 8 therefore those who utter unrighteous things will not escape notice, and justice, when it punishes, will not pass them by. 9 For inquiry will be made into the counsels of the ungodly, and a report of their words will come to the Lord, to convict them of their lawless deeds; 10 because a jealous ear hears all things, and the sound of grumbling does not go unheard. 11 Beware then of useless grumbling, and keep your tongue from slander; because no secret word is without result, a and a lying mouth destroys the soul.
Augustine City of God 20.26
On the City of God Against the PagansThen, with reference to those who are worthy not of cleansing but of damnation, He says, And I will draw near to you to judgment, and I will be a swift witness against evildoers and against adulterers; and after enumerating other damnable crimes, He adds, For I am the Lord your God, and I am not changed. It is as if He said, Though your fault has changed you for the worse, and my grace has changed you for the better, I am not changed. And he says that He Himself will be a witness, because in His judgment He needs no witnesses; and that He will be swift, either because He is to come suddenly, and the judgment which seemed to lag shall be very swift by His unexpected arrival, or because He will convince the consciences of men directly and without any prolix harangue. For, as it is written, in the thoughts of the wicked His examination shall be conducted. And the apostle says, The thoughts accusing or else excusing, in the day in which God shall judge the hidden things of men, according to my gospel in Jesus Christ. Thus, then, shall the Lord be a swift witness, when He shall suddenly bring back into the memory that which shall convince and punish the conscience.
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 ..."
