Caesarius, bishop of Arles (470-543):
"Similarly, one who refuses to read the sacred writings which have been transmitted from the eternal country should fear that he perhaps will not receive eternal rewards and even not escape endless punishment. So dangerous is it not to read the divine precepts that the Prophet mournfully exclaims: ‘Therefore is my people led away captive, because they had not knowledge.’ ‘If anyone ignores this, he shall be ignored.’ Doubtless, if a man fails to seek God in this world through the sacred lessons, God will refuse to recognize him in eternal bliss. . . . A man should first be willing to listen to God, if he wants to be heard by Him. Indeed, with what boldness does he want God to hear him when he despises God so much that he refuses to read His precepts?"

"I beseech you, beloved brethren, be eager to engage in divine reading whatever hours you can. Moreover, since what a man procures in this life by reading or good works will be food of his soul forever, let no one try to excuse himself by saying he has not learned letters at all. If those who are illiterate love God in truth, they look for learned people who can read the sacred Scriptures to them."

"Therefore consider at once, brethren, and carefully notice that the man who frequently reads or listens to sacred Scripture speaks with God. See, then, whether the Devil can overtake him when he perceives him in constant conversation with God. However, if a man neglects to do this, with what boldness or with what feelings does he believe God will grant him an eternal reward, when he refuses to speak with Him in this world through the divine text?"

"For this reason I beseech you with fatherly solicitude, equally admonishing and exhorting you, as was already said, to endeavor continually to read the sacred lessons yourselves or willingly to listen to others read them. By thus always thinking over in the treasury of your heart what is just and holy, you may prepare for your souls an eternal spiritual food that will bring you endless bliss."

"Let us examine the Scriptures, and in them we will be able to understand this more clearly."

"When the Gospel was read, we heard that word which is at the same time both terrible and desirable, the sentence of our Lord which is equally dreadful and desirable. It is terrible because of what He says: ‘Depart from me, accursed ones, into the everlasting fire’; it is desirable because of the words: ‘Come, blessed, receive the kingdom.’ . . . For if a man carefully heeds this lesson, even if he cannot read the rest of the Scriptures, this lesson alone can suffice for him to perform every good act and to avoid all evil."

"We want to confirm the evidence of Sacred Scripture where the Holy Spirit can clearly be recognized as equal to the Father and to the Son in all powers."

"We have gathered these facts as well as we could, dearly beloved, from the different books of Scripture for the progress of your soul, and we suggest them to the consideration of your charity. If, with the Lord's help, you will read over the Sacred Scriptures rather frequently and heed them carefully, I believe that you can find an even better explanation."

"Willingly listen to the divine lessons in church, as you usually do, and read them over again in your own homes. If anyone is so busy that he cannot take time for holy Scripture before lunch, he should not be ashamed to read over something of it at his own little meal. In this way just as the body is fed with food, so the soul is refreshed by the word of God, the handmaid is satisfied but the mistress is tormented by hunger, and your holy selves know how wrong this is. For this reason, as I have already said, you ought to read and listen to the sacred lessons with such eagerness that you may be able to speak about them and teach them to others both in your own homes and elsewhere, wherever you are. As you, like clean animals, masticate the word of God by continuous reflection, you may be able both to procure useful flavor for yourselves, that is, their spiritual meaning, and with God’s help give it to others."

"Sacred Scripture speaks about the godhead and divinity of the Holy Spirit, but does not say whether He should be called begotten or unbegotten. See what confusion a lack of faith creates. You do not want to know what God did not want to be unknown, and you want to know what He did not decree should be asked. . . .
You ask whether He [i.e. the Holy Spirit] was begotten or not. Sacred Scripture has said nothing about this, and it is wrong to violate the divine silence. Since God did not think that this should be indicated in His writings, He did not want you to question or to know through idle curiosity. "
