The Holy Scriptures

“When the Bible lies open on the preacher’s desk and the preparation of the sermon is about to begin, the worshippers have already come in; the passage contains these people since it is God’s Word to his people.”   

Gustaf Wingren - The Living Word

A READING FROM THE BOOK OF CONCORD
ADVENT 1
LARGE CATECHISM, MARTIN LUTHER'S PREFACE
Nothing is so effectual against the devil, the world, the flesh, and all evil thoughts as to occupy oneself with the Word of God, talk about it, and meditate on it. Psalm 1 calls those blessed who "meditate on God's law day and night." You will never offer up any incense or other savor more potent against the devil than to occupy yourself with God's commandments and words and to speak, sing, and meditate on them. This, indeed, is the true holy water, the sign which routs the devil and puts him to flight.
For this reason alone you should eagerly read, recite, ponder, and practice the Catechism, even if the only blessing and benefit you obtain from it is to rout the devil and evil thoughts. For he cannot bear to hear God's Word. God's Word is not like some empty tale, but as St. Paul says in Romans 1:16 it is the power of God, indeed, the power of God which burns the devil and gives us immeasurable strength, comfort, and help.
Time and paper would fail me if I were to recount all the blessings that flow from God's Word. The devil is called the master of a thousand arts. What, then, shall we call God's Word, which routs and destroys this master of a thousand arts with all his wiles and might? It must indeed, be master of more than a hundred thousand arts.
Shall we frivolously despise this might, blessing, power, and fruit?

St. Athanasius (c.296-373):
The holy and inspired Scriptures are fully sufficient for the proclamation of the truth.
(Against the Heathen, I:3, quoted in Carl A. Volz, Faith and Practice in the Early Church [Minneapolis: Augsburg Publishing House, 1983], p. 147.)

St. Cyril of Jerusalem (c.310-386):
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 you these things, give not absolute credence, unless you 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, IV:17, in The Nicene and Post-Nicene Fathers [Grand Rapids, Michigan: William B. Eerdmans Publishing Company, 1983 reprint], Second Series, Volume VII, p. 23.)

St. Gregory of Nyssa (330-395):
...we are not entitled to such license, namely, of affirming whatever we please. For we make Sacred Scripture the rule and the norm of every doctrine. Upon that we are obliged to fix our eyes, and we approve only whatever can be brought into harmony with the intent of these writings.
(On the Soul and the Resurrection, quoted in Jaroslav Pelikan, The Emergence of the Catholic Tradition [Chicago: University of Chicago Press, 1971], p. 50.)

St. Augustine of Hippo (354-430):
Let them show their church if they can, not by the speeches and mumblings of the Africans, not by the councils of their bishops, not by the writings of any of their champions, not by fraudulent signs and wonders, because we have been prepared and made cautious also against these things by the Word of the Lord; but [let them show their church] by a command of the Law, by the predictions of the prophets, by songs from the Psalms, by the words of the Shepherd Himself, by the preaching and labors of the evangelists; that is, by all the canonical authorities of the sacred books.
(On the Unity of the Church, 16, quoted in Martin Chemnitz, Examination of the Council of Trent, Part I [Saint Louis: Concordia Publishing House, 1971], p. 159.)

St. Augustine of Hippo again:
What more can I teach you, than what we read in the Apostle? For Holy Scripture sets a rule to our teaching, that we dare not "be wise more than it behooves to be wise," but be wise, as he says, "unto soberness, according as unto each God has allotted the measure of faith."
(On the Good of Widowhood, 2, in The Nicene and Post-Nicene Fathers, First Series, Volume III, p. 442. The quotation is from Romans 12:3.)

St. John Chrysostom (c.347-407):
Let us not therefore carry about the notions of the many, but examine into the facts. For how is it not absurd that in respect to money, indeed, we do not trust to others, but refer to [our own] calculation; but in calculating upon [theological] facts we are lightly drawn aside by the notions of others; and that too, though we possess an exact balance, and square and rule for all things, the declaration of the divine laws? Wherefore I exhort and entreat you all, disregard what this man and that man thinks about these things, and inquire from the Scriptures all these things; and having learned what are the true riches, let us pursue after them that we may obtain also the eternal good things...
(Homily 13 on 2 Corinthians, in The Nicene and Post-Nicene Fathers, First Series, Volume XII, p. 346.)

St. Basil the Great (c.329-379):
They are charging me with innovation, and base their charge on my confession of three hypostases [persons], and blame me for asserting one Goodness, one Power, one Godhead. In this they are not wide of the truth, for I do so assert. Their complaint is that their custom does not accept this, and that Scripture does not agree. What is my reply? I do not consider it fair that the custom which obtains among them should be regarded as a law and rule of orthodoxy. If custom is to be taken in proof of what is right, then it is certainly competent for me to put forward on my side the custom which obtains here. If they reject this, we are clearly not bound to follow them. Therefore let God-inspired Scripture decide between us; and on whichever side be found doctrines in harmony with the Word of God, in favor of that side will be cast the vote of truth.
(Letter 189 [to Eustathius the physician], 3, in The Nicene and Post-Nicene Fathers, Second Series, Volume VIII, p. 229.)
