Whoever, then, thinks that he understands the Holy Scriptures, or any part of them, but puts such an interpretation upon them as does not tend to build up this twofold love of God and our neighbour, does not yet understand them as he ought. If, on the other hand, a man draws a meaning from them that may be used for the building up of love, even though he does not happen upon the precise meaning which the author whom he reads intended to express in that place, his error is not pernicious, and he is wholly clear from the charge of deception.
Whoever takes another meaning out of Scripture than the writer intended, goes astray, but not through any falsehood in Scripture. Nevertheless, as I was going to say, if his mistaken interpretation tends to build up love, which is the end of the commandment, he goes astray in much the same way as a man who by mistake quits the high road, but yet reaches through the fields the same place to which the road leads. He is to be corrected, however, and to be shown how much better it is not to quit the straight road, lest, if he get into a habit of going astray, he may sometimes take cross roads, or even go in the wrong direction altogether.
(On Christian Doctrine, Book I, Chapter 36)
This passage left me wondering: How different would theological discussions/controversies look if participants operated with a mindset similar to what Augustine describes? Food for thought.
