St. Augustine suggested a method to improve the Biblical exegesis in presence of particularly difficult passages. Readers shall believe all the Scripture is inspired by God and that each author wrote nothing in which he did not believe personally, or that he believed to be false. Readers must distinguish philologically, and keep separate, their own interpretations, the written message and the originally intended meaning of the messenger and author (in Latin: intentio).[17]
Disagreements may arise "either as to the truth of the message itself or as to the messenger's meaning" (XII.23). The truthfulness of the message itself is granted by God who inspired it to the extensor and who made possible the transmission and spread of the content across centuries and among believers.[17]
In principle, the reader isn't capable of ascertaining what the author had in mind when he wrote a biblical book, but he has the duty to do his best to approach that original meaning and intention without contradicting the letter of the written text. The interpretation must stay "within the truth" (XII.25) and not outside it.[17]
