The origin of this tradition comes from the Book of Esdras.
Deus glorificatus est, et Scripturæ veræ divinæ creditæ sunt, omnibus eandem et eisdem verbis et eisdem nominibus recitantibus ab initio usque ad finem, uti et præsentes gentes cognoscerent quoniam per inspirationem Dei interpretatæ sunt Scripturæ, et non esset mirabile Deum hoc in eis operatum, quando in ea captivitate populi quæ facta est a Nabuchodonosor corruptis Scripturis et post septuaginta annos Judæis descendentibus in regionem suam, et post deinde temporibus Artaxexis Persarum regis inspiravit Hesdræ sacerdoti tribus Levi præteritorum prophetarum omnes rememorare sermones et restituere populo eam legem quæ data est per Moysen.
Against the Story in Esdras, II. Maccab. 2. Josephus, Antiquities, II. 1.—Cyrus took occasion from the prophecy of Isaiah to release the people. The Jews held property in peace under Cyrus in Babylon, therefore they might well have the Law.
Josephus, in the whole history of Esdras, says not a single word of this restoration.—II. Kings, xvii. 37.
Scripture has provided passages of consolation and warning for every condition of life.
Nature seems to have done the same thing by her two infinities, natural and moral, for we shall always have those who are higher and lower, who are more and less able, who are noble and in low estate, in order to abate our pride, and raise our lowliness.
Order, against the objection that the Scripture has no order.—The heart has its own order; the mind too has its own, which is by premisses and demonstrations, that of the heart is wholly different. It were absurd to prove that we are worthy of love by putting forth in order the causes of love.
Jesus Christ and Saint Paul use the order of charity, not of the intellect, for they wish to warm, not to teach; the same with Saint Augustine. This order consists mainly in digressions on each point which may illustrate the main end, and keep it ever in view.
God and the Apostles foreseeing that the seed of pride would cause heresies to spring up, and not wishing to give them occasion to arise by defining them, have placed in the Scripture and the prayers of the Church contrary words and sentences to produce their fruit in time.
So in morals he gives charity to produce fruits contrary to lust.
