Augustine of Hippo on Knowledge

"The mind itself, its love and its knowledge are a kind of trinity."

"There is another form of temptation, more complex in its peril. … It originates in an appetite for knowledge. … From this malady of curiosity are all those strange sights exhibited in the theatre. Hence do we proceed to search out the secret powers of nature , which to know profits not, and wherein men desire nothing but to know."

"Therefore, on hearing His words let no one say either: "These are not Christ's words," or "These are not my words." On the contrary, if he knows that he is in the body of Christ, let him say: "These are both Christ's words and my words." Say nothing without Him, and He will say nothing without thee. We must not consider ourselves as strangers to Christ, or look upon ourselves as other than Himself."

"In order to understand the Scriptures, it is absolutely necessary to know the whole, complete Christ, that is, Head and members. For sometimes Christ speaks in the name of the Head alone … sometimes in the name of His body, which is the holy Church spread over the entire earth. And we are in His body … and we hear ourselves speaking in it, for the Apostle tells us: “We are members of His body” . In many places does the Apostle tell us this."

"Let us rejoice and give thanks. Not only are we become Christians, but we are become Christ. My brothers, do you understand the grace of God that is given us? Wonder, rejoice, for we are made Christ! If He is the Head, and we the members, then together He and we are the whole man.... This would be foolish pride on our part, were it not a gift of his bounty. But this is what He promised by the mouth of the Apostle: “You are the body of Christ, and severally His members” ."

"What, then, does He say? "Blessed are the poor in spirit, for theirs is the kingdom of heaven." We read in Scripture concerning the striving after temporal things, "All is vanity and presumption of spirit"; but presumption of spirit means audacity and pride: usually also the proud are said to have great spirits; and rightly, inasmuch as the wind also is called spirit. And hence it is written, "Fire, hail, snow, ice, spirit of tempest." But, indeed, who does not know that the proud are spoken of as puffed up, as if swelled out with wind? And hence also that expression of the apostle, "Knowledge puffs up, but charity edifies". And the poor in spirit are rightly understood here, as meaning the humble and God-fearing, i.e. those who have not the spirit which puffs up. Nor ought blessedness to begin at any other point whatever, if indeed it is to attain unto the highest wisdom; "but the fear of the Lord is the beginning of wisdom"; for, on the other hand also, "pride" is entitled "the beginning of all sin." Let the proud, therefore, seek after and love the kingdoms of the earth; but "blessed are the poor in spirit, for theirs is the kingdom of heaven."

"To such a one my answer is that I have arrived at a nourishing kernel in that I have learnt that a man is not in any difficulty in making a reply according to his faith which he ought to make to those who try to defame our Holy Scripture. When they are able, from reliable evidence, to prove some fact of physical science, we shall show that it is not contrary to our Scripture. But when they produce from any of their books a theory contrary to Scripture, and therefore contrary to the Catholic faith, either we shall have some ability to demonstrate that it is absolutely false, or at least we ourselves will hold it so without any shadow of a doubt. And we will so cling to our Mediator, “in whom are hidden all the treasures of wisdom and knowledge,” that we will not be led astray by the glib talk of false philosophy or frightened by the superstition of false religion. When we read the inspired books in the light of this wide variety of true doctrines which are drawn from a few words and founded on the firm basis of Catholic belief, let us choose that one which appears as certainly the meaning intended by the author. But if this is not clear, then at least we should choose an interpretation in keeping with the context of Scripture and in harmony with our faith. But if the meaning cannot be studied and judged by the context of Scripture, at least we should choose only that which our faith demands. For it is one thing to fail to recognize the primary meaning of the writer, and another to depart from the norms of religious belief. If both these difficulties are avoided, the reader gets full profit from his reading."
