Saint Cyril of Jerusalem (313-386 A.D.):
“No doctrine concerning the divine and saving mysteries of the faith, however trivial, may be taught without the backing of the holy Scriptures. We must not let ourselves be drawn aside by mere persuasion and cleverness of speech. Do not even give absolute belief to me, the one who tells you these things, unless you receive proof from the divine Scriptures of what I teach. For the faith that brings us salvation acquires its force, not from fallible reasonings, but from what can be proved out of the holy Scriptures.”
“For concerning the divine and holy mysteries of the Faith, not even a casual statement must be delivered without the Holy Scriptures; nor must we be drawn aside by mere plausibility and artifices of speech. Even to me, who tell thee these things, give not absolute credence, unless thou receive the proof of the things which I announce from the Divine Scriptures. For this salvation which we believe depends not on ingenious reasoning, but on demonstration of the Holy Scriptures.” (Catechetical Lectures, 4:17)
“This seal have thou ever on thy mind; which now by way of summary has been touched on in its heads, and if the Lord grant, shall hereafter be set forth according to our power, with Scripture-proofs. For concerning the divine and sacred Mysteries of the Faith, we ought not to deliver even the most casual remark without the Holy Scriptures: nor be drawn aside by mere probabilities and the artifices of argument. Do not then believe me because I tell thee these things, unless thou receive from the Holy Scriptures the proof of what is set forth: for this salvation, which is of our faith, is not by ingenious reasonings, but by proof from the Holy Scriptures.” (A Library of the Fathers of the Holy Catholic Church, Oxford: Parker, 1845, The Catechetical Lectures of S. Cyril 4.17).
Saint Gregory of Nyssa (335-395 A.D.):
“We treat the Holy Bible as the test of every dogma and rule, excepting [should read "accepting"] only such things that agree with the meaning of scripture.”
“We make the Holy Scriptures the rule and the measure of every tenet; we necessarily fix our eyes upon that, and approve that alone which may be made to harmonize with the intention of those writings…And to those who are expert only in the technical methods of proof a mere demonstration suffices to convince; but as for ourselves, we were agreed that there is something more trustworthy than any of these artificial conclusions, namely, that which the teachings of Holy Scripture point to: and so I deem that it is necessary to inquire, in addition to what has been said, whether this inspired teaching harmonizes with it all. And who, she replied, could deny that truth is to be found only in that upon which the seal of Scriptural testimony is set?” - (On the Soul and the Resurrection)
Saint Irenaeus of Lyon (circa 115-175 A.D.):
“They [heretics] gather their views from other sources than the Scriptures…We have learned from none others the plan of our salvation, than from those through whom the Gospel has come down to us, which they did at one time proclaim in public, and, at a later period, by the will of God, handed down to us in the Scriptures, to be the ground and pillar of our faith….It is within the power of all, therefore, in every Church, who may wish to see the truth, to contemplate clearly the tradition of the apostles manifested throughout the whole world; and we are in a position to reckon up those who were by the apostles instituted bishops in the Churches, and to demonstrate the succession of these men to our own times; those who neither taught nor knew of anything like what these heretics rave about. For if the apostles had known hidden mysteries, which they were in the habit of imparting to ‘the perfect’ apart and privily from the rest, they would have delivered them especially to those to whom they were also committing the Churches themselves. For they were desirous that these men should be very perfect and blameless in all things, whom also they were leaving behind as their successors, delivering up their own place of government to these men; which men, if they discharged their functions honestly, would be a great boon to the Church, but if they should fall away, the direst calamity….proofs of the things which are contained in the Scriptures cannot be shown except from the Scriptures themselves.” (Against Heresies, 1:8:1, 3:1:1, 3:3:1, 3:12:9)
Saint Bede the Venerable (672-735 A.D.):
"Holy Scripture is above all other books, not only by its authority, because it is divine, or by its utility, because it leads to eternal life, but also by its antiquity and by its literary form."
Saint John Chrysostom of Constantinople (347–407 A.D.):
"Now if we are willing to examine the Scriptures in this way, carefully and systematically, we shall be able to obtain our salvation. If we unceasingly are preoccupied with them, we shall learn both correctness of doctrine and an upright way of life. (Homily 53 On John)
"This is the cause of all evils, the not knowing the Scriptures. We go into battle without arms, and how are we to come off safe?" (Homily IX On Colossians)
“That which the Scriptures state, ‘the Lord himself has said’, and so, even if someone were to rise from the dead or an angel were to come down from heaven, they would not deserve more credence than the Scriptures.”
"The Holy Scriptures were not given to us that we should enclose them in books, but that we should engrave them upon our hearts."
Saint Innocent of Alaska (August 26, 1797 - March 31, 1879 A.D.):
"First of all, a Christian must thoroughly study the foundations of the Christian faith. To that end, you must read and reread the Holy Scriptures on a regular basis, especially the books of the New Testament. You must not only learn their contents but also develop an interest in their origin, who wrote them and when, how they were preserved and have been handed down to us, and why they are called Divine and Sacred. You must study the Holy Books with simplicity of heart, without prejudice or excessive inquisitiveness, not trying to discover hidden mysteries but trying to learn that which leads us to self-improvement. Certainly all that is necessary for us to know for our salvation is revealed quite clearly and in detail in the Scriptures."
Hippolytus of Rome (170-235 A.D.):
“Some others are secretly introducing another doctrine, who have become disciples of one Noetus, who was a native of Smyrna, and lived not very long ago. This person was greatly puffed up and inflated with pride, being inspired by the conceit of a strange spirit. He alleged that Christ was the Father Himself, and that the Father Himself was born, and suffered, and died….But the case stands not thus; for the Scriptures do not set forth the matter in this manner….the Scriptures themselves confute their senselessness, and attest the truth…The Scriptures speak what is right; but Noetus is of a different mind from them. Yet, though Noetus does not understand the truth, the Scriptures are not at once to be repudiated….The proper way, therefore, to deal with the question is first of all to refute the interpretation put upon these passages [of scripture] by these men, and then to explain their real meaning….For whenever they wish to attempt anything underhand, they mutilate the Scriptures. But let him quote the passage as a whole, and he will discover the reason kept in view in writing it….if they choose to maintain that their dogma is ratified by this passage [of scripture], as if He owned Himself to be the Father, let them know that it is decidedly against them, and that they are confuted by this very word….Many other passages [of scripture], or rather all of them, attest the truth. A man, therefore, even though he will it not, is compelled to acknowledge God the Father Almighty, and Christ Jesus the Son of God, who, being God, became man, to whom also the Father made all things subject, Himself excepted, and the Holy Spirit; and that these, therefore, are three. But if he desires to learn how it is shown still that there is one God, let him know that His power is one….What, then, will this Noetus, who knows nothing of the truth, dare to say to these things? And now, as Noetus has been confuted, let us turn to the exhibition of the truth itself, that we may establish the truth, against which all these mighty heresies have arisen without being able to state anything to the purpose. There is, brethren, one God, the knowledge of whom we gain from the Holy Scriptures, and from no other source. For just as a man, if he wishes to be skilled in the wisdom of this world, will find himself unable to get at it in any other way than by mastering the dogmas of philosophers, so all of us who wish to practise piety will be unable to learn its practice from any other quarter than the oracles of God. Whatever things, then, the Holy Scriptures declare, at these let us took; and whatsoever things they teach, these let us learn; and as the Father wills our belief to be, let us believe; and as He wills the Son to be glorified, let us glorify Him; and as He wills the Holy Spirit to be bestowed, let us receive Him. Not according to our own will, nor according to our own mind, nor yet as using violently those things which are given by God, but even as He has chosen to teach them by the Holy Scriptures, so let us discern them.” (Against the Heresy of One Noetus, 1-4, 7-9)
Saint Ambrose of Milan (340-4 April, 397 A.D.):
“For how can we adopt those things which we do not find in the holy Scriptures?” (On the Duties of the Clergy, 1:23:102)
“The Arians, then, say that Christ is unlike the Father; we deny it. Nay, indeed, we shrink in dread from the word. Nevertheless I would not that your sacred Majesty should trust to argument and our disputation. Let us enquire of the Scriptures, of apostles, of prophets, of Christ. In a word, let us enquire of the Father…So, indeed, following the guidance of the Scriptures, our fathers [at the Council of Nicaea] declared, holding, moreover, that impious doctrines should be included in the record of their decrees, in order that the unbelief of Arius should discover itself, and not, as it were, mask itself with dye or face-paint.” (Exposition of the Christian Faith, 1:6:43, 1:18:119)
Saint Clement of Alexandria (150-215 A.D.):
“But those who are ready to toil in the most excellent pursuits, will not desist from the search after truth, till they get the demonstration from the Scriptures themselves.” – Clement of Alexandria (The Stromata, 7:16)
Saint Cyprian of Carthage (circa 200–September 14, 258 A.D.):
“Let nothing be innovated, says he, nothing maintained, except what has been handed down. Whence is that tradition? Whether does it descend from the authority of the Lord and of the Gospel, or does it come from the commands and the epistles of the apostles? For that those things which are written must be done, God witnesses and admonishes, saying to Joshua the son of Nun: ‘The book of this law shall not depart out of thy mouth; but thou shalt meditate in it day and night, that thou mayest observe to do according to all that is written therein.’ Also the Lord, sending His apostles, commands that the nations should be baptized, and taught to observe all things which He commanded. If, therefore, it is either prescribed in the Gospel, or contained in the epistles or Acts of the Apostles, that those who come from any heresy should not be baptized, but only hands laid upon them to repentance, let this divine and holy tradition be observed.” (Letter 73:2)
Saint Dionysius the Great of Alexandria (circa 200 A.D.-November 17, 265 A.D.):
“Nor did we evade objections, but we endeavored as far as possible to hold to and confirm the things which lay before us, and if the reason given satisfied us, we were not ashamed to change our opinions and agree with others; but on the contrary, conscientiously and sincerely, and with hearts laid open before God, we accepted whatever was established by the proofs and teachings of the Holy Scriptures.” (cited in Ecclesiastical History, Eusebius, 7:24)
Saint Basil the Great of Caesarea (circa. 329-January 1, 379 A.D.):
Enjoying as you do the consolation of the Holy Scriptures, you stand in need neither of my assistance nor of that of anybody else to help you comprehend your duty. You have the all-sufficient counsel and guidance of the Holy Spirit to lead you to what is right (Letter CCLXXXIII, ANCF, p. 312).
Saint Hilary of Poitiers (circa 300-368 A.D.):
“Their treason involves us in the difficult and dangerous position of having to make a definite pronouncement, beyond the statements of Scripture, upon this grave and abstruse matter….We must proclaim, exactly as we shall find them in the words of Scripture, the majesty and functions of Father, Son and Holy Spirit, and so debar the heretics from robbing these Names of their connotation of Divine character, and compel them by means of these very Names to confine their use of terms to their proper meaning….I would not have you flatter the Son with praises of your own invention; it is well with you if you be satisfied with the written word.” (On the Trinity, 2:5, 3:23)
Saint Jerome (347-30 September, 420 A.D.):
“When, then, anything in my little work seems to you harsh, have regard not to my words, but to the Scripture, whence they are taken.” (Letter, 48:20)
“I beg of you, my dear brother, to live among these books [Scriptures], to meditate upon them, to know nothing else, to seek nothing else.” (Letter, 53:10)
“When Paula comes to be a little older and to increase like her Spouse in wisdom and stature and in favour with God and man, let her go with her parents to the temple of her true Father but let her not come out of the temple with them. Let them seek her upon the world’s highway amid the crowds and the throng of their kinsfolk, and let them find her nowhere but in the shrine of the Scriptures” (Letter, 107:7)
Justin Martyr (100-165 A.D.):
“And now, if I say this to you, although I have repeated it many times, I know that it is not absurd so to do. For it is a ridiculous thing to see the sun, and the moon, and the other stars, continually keeping the same course, and bringing round the different seasons; and to see the computer who may be asked how many are twice two, because he has frequently said that they are four, not ceasing to say again that they are four; and equally so other things, which are confidently admitted, to be continually mentioned and admitted in like manner; yet that he who founds his discourse on the prophetic Scriptures should leave them and abstain from constantly referring to the same Scriptures, because it is thought he can bring forth something better than Scripture. The passage, then, by which I proved that God reveals that there are both angels and hosts in heaven is this: ‘Praise the Lord from the heavens: praise Him in the highest. Praise Him, all His angels: praise Him, all His hosts.’” (Dialogue with Trypho, 85)
Theodoret of Cyrus (393-457 A.D.):
“I shall yield to Scripture alone.” (Dialogues, 1)
Elder Cleopa of Romania (10 April 1912 - 2 December 1998):
"Holy Scripture contains within it unanswerable passages or, as Saint Gregory of Nyssa puts it, 'strong bones'. Some would like to break these bones of Scripture with their wisdom teeth as of yet still only suitable for sucking milk. However, such a thing they would never be able to manage. All who have desired to plunge into the depths of Scripture have drowned in the fathomless ocean that is the wisdom of God. Such was the portion shared by Origen, Arius, Macedonius, Nestorius, Sabellius, Dioscorus, Eutyches and all the other chiefs of the ancient heresies who have been swallowed up in the unfathomable sea of Holy Scripture. The profundity and depth of Scripture was not the cause of their fall and drowning, but rather they themselves were the cause, due to their own insufficiencies, of being drowned in the depths of the mysteries of the Scriptures.
"Holy Scripture is like a fountain or an endless spring, of the wisdom of God in which we must be steeped and partake in accordance with our level of wisdom and spiritual maturity. Just as we take water from the well with a bucket, empty it into our pitcher and then into our glass in order to quench our bodys thirst, so must we also do with our spiritual thirst when we are urged to drink of the deepest ocean of wisdom, the Holy Scriptures. Thus, spiritually speaking, if we draw more water from the well of Scripture than is drinkable (out of desire for the purity of our intellect (νούς) and heart), due to our pride and inquisitiveness we will be destroyed in our attempt to grasp the incomprehensible with our limited human faculties. If, for example, we were to see a child from the first grade trying to learn and to teach others that which is taught at the university, how much laughter and amusement would it provoke in us! The same and worse happens to those who desire to scrutinize and unravel the incomprehensible mysteries of the Scriptures with an intellect inexperienced and unenlightened by the Holy Spirit."
