Here are a few ancient testimonies to the self-attesting nature of God speaking in Holy Scripture.
[b:96bf9a86dc]Justin Martyr (wrote after 151):[/b:96bf9a86dc] The word of truth is free, and carries its own authority, disdaining to fall under any skilful argument, or to endure the logical scrutiny of its hearers. But it would be believed for its own nobility, and for the confidence due to Him who sends it. Now the word of truth is sent from God; wherefore the freedom claimed by the truth is not arrogant. For being sent with authority, it were not fit that it should be required to produce proof of what is said; since neither is there any proof beyond itself, which is God. For every proof is more powerful and trustworthy than that which it proves; since what is disbelieved, until proof is produced, gets credit when such proof is produced, and is recognised as being what it was stated to be. But nothing is either more powerful or more trustworthy than the truth; so that he who requires proof of this is like one who wishes it demonstrated why the things that appear to the senses do appear. For the test of those things which are received through the reason, is sense; but of sense itself there is no test beyond itself. As then we bring those things which reason hunts after, to sense, and by it judge what kind of things they are, whether the things spoken be true or false, and then sit in judgment no longer, giving full credit to its decision; so also we refer all that is said regarding men and the world to the truth, and by it judge whether it be worthless or no. But the utterances of truth we judge by no separate test, giving full credit to itself. And God, the Father of the universe, who is the perfect intelligence, is the truth. And the Word, being His Son, came to us, having put on flesh, revealing both Himself and the Father, giving to us in Himself resurrection from the dead, and eternal life afterwards. And this is Jesus Christ, our Saviour and Lord. He, therefore, is Himself both the faith and the proof of Himself and of all things. Wherefore those who follow Him, and know Him, having faith in Him as their proof, shall rest in Him. But since the adversary does not cease to resist many, and uses many and divers arts to ensnare them, that he may seduce the faithful from their faith, and that he may prevent the faithless from believing, it seems to me necessary that we also, being armed with the invulnerable doctrines of the faith, do battle against him in behalf of the weak. [i:96bf9a86dc]ANF: Vol. I, Fragments of the lost Work of Justin on the Resurrection[/i:96bf9a86dc], Chapter I.
[b:96bf9a86dc]Clement of Alexandria (150 - c. 215):[/b:96bf9a86dc] The exercise of faith directly becomes knowledge, reposing on a sure foundation. Knowledge, accordingly, is defined by the sons of the philosophers as a habit, which cannot be overthrown by reason. Is there any other true condition such as this, except piety, of which alone the Word is teacher? I think not. Theophrastus says that sensation is the root of faith. For from it the rudimentary principles extend to the reason that is in us, and the understanding. He who believeth then the divine Scriptures with sure judgment, receives in the voice of God, who bestowed the Scripture, a demonstration that cannot be impugned. Faith, then, is not established by demonstration. "œBlessed therefore those who, not having seen, yet have believed." [i:96bf9a86dc]ANF: Vol. II, The Stromata[/i:96bf9a86dc], Book II, Chapter II.""The Knowledge of God Can Be Attained Only Through Faith.
[b:96bf9a86dc]Clement of Alexandria (150 - c. 215):[/b:96bf9a86dc] It will naturally fall after these, after a cursory view of theology, to discuss the opinions handed down respecting prophecy; so that, having demonstrated that the Scriptures which we believe are valid from their omnipotent authority, we shall be able to go over them consecutively, and to show thence to all the heresies one God and Omnipotent Lord to be truly preached by the law and the prophets, and besides by the blessed Gospel. Many contradictions against the heterodox await us while we attempt, in writing, to do away with the force of the allegations made by them, and to persuade them against their will, proving by the Scriptures themselves. [i:96bf9a86dc]ANF: Vol. II, The Stromata[/i:96bf9a86dc], Book IV, Chapter 1.
[b:96bf9a86dc]Lactantius (260-330):[/b:96bf9a86dc] For since all error arises either from false religion or from wisdom, in refuting error it is necessary to overthrow both. For inasmuch as it has been handed down to us in the sacred writings that the thoughts of philosophers are foolish, this very thing is to be proved by fact and by arguments, that no one, induced by the honourable name of wisdom, or deceived by the splendour of empty eloquence, may prefer to give credence to human rather than to divine things. Which things, indeed, are related in a concise and simple manner. For it was not befitting that, when God was speaking to man, He should confirm His words by arguments, as though He would not otherwise be regarded with confidence: but, as it was right, He spoke as the mighty Judge of all things, to whom it belongs not to argue, but to pronounce sentence. He Himself, as God, is truth. But we, since we have divine testimony for everything, will assuredly show by how much surer arguments truth may be defended, when even false things are so defended that they are accustomed to appear true. Wherefore there is no reason why we should give so much honour to philosophers as to fear their eloquence. For they might speak well as men of learning; but they could not speak truly, because they had not learned the truth from Him in whose power it was.

[b:96bf9a86dc]Hilary of Poitiers (c 315-67):[/b:96bf9a86dc] For he is the best student who does not read his thoughts into the book, but lets it reveal its own; who draws from it its sense, and does not import his own into it, nor force upon its words a meaning which he had determined was the right one before he opened its pages. Since then we are to discourse of the things of God, let us assume that God has full knowledge of Himself, and bow with humble reverence to His words. For He Whom we can only know through His own utterances is the fitting witness concerning Himself. [i:96bf9a86dc]NPNF2: Vol. IX, On the Trinity[/i:96bf9a86dc], Book I, §18.
[b:96bf9a86dc]Nemesius of Emesa (Late 4th Century):[/b:96bf9a86dc] But for us the sufficient demonstration of the soul"(tm)s immortality is the teaching of Holy Scripture, which is self-authenticating because inspired of God. William Telfer, ed., [i:96bf9a86dc]The Library of Christian Classics, Vol. IV, Cyril of Jerusalem and Nemesius of Emesa: On the Nature of Man[/i:96bf9a86dc], Chapter 2 Of the soul (Philadelphia: The Westminster Press, 1955), p. 292. It is believed that Nemesius of Emesa wrote this work sometime between the years 392-400 AD (p. 206).
[b:96bf9a86dc]Epiphanius (310/320-403)[/b:96bf9a86dc] expressed his belief that "œthe truth is self-authenticating and cannot be overthrown even if wickedness shamelessly opposes the precept of truth;" Frank Williams, trans., [i:96bf9a86dc]The Panarion of Epiphanius of Salamis[/i:96bf9a86dc], Books II and III (Sects 47-80, De Fide), 66. Against Manichaeans, 10,4 (Leiden: E.J. Brill, 1994), p. 230.
[b:96bf9a86dc]Augustine (354-430)[/b:96bf9a86dc] stated explicitly that "œthe truth is sufficient for its own testimony." [i:96bf9a86dc]NPNF1: Volume VII, Tractates on John[/i:96bf9a86dc], Tractate 7, §16, John 1:34-51. Latin text: sufficit sibi ad testimonium suum veritas. [i:96bf9a86dc]In Joannis Evangelium[/i:96bf9a86dc], Tractatus VII, 16, PL 35:1445.
[b:96bf9a86dc]Salvian the Presbyter (5th century):[/b:96bf9a86dc] I need not prove by arguments what God Himself proves by His own words. When we read that God says He perpetually sees the entire earth, we prove thereby that He does see it because He Himself says He sees it. When we read that He rules all things He has created, we prove thereby that He rules, since He testifies that He rules. When we read that He ordains all things by His immediate judgment, it becomes evident by this very fact, since He confirms that He passes judgment. All other statements, said by men, require proofs and witnesses. God"(tm)s word is His own witness, because whatever uncorrupted Truth says must be the undefiled testimony to truth.

Therefore, when [b:96bf9a86dc]Calvin[/b:96bf9a86dc] affirmed that "œGod alone is a fit witness of himself in his Word," he was but echoing the patristic consensus itself, which recognized and submitted to the witness of God in Holy Scripture.
