How to read this
Each entry gives the quotation exactly as it appears in the book, the citation the book gives for it, and what the cited source actually contains. Where the real text is available, it is reproduced so readers can compare for themselves.
A quotation in quotation marks is a claim that those are the words in the source. That is the standard each entry is held to.
The words are not in the cited source, the cited source does not exist, or the historical record says something different.
The quote appears nowhere except Breaker’s book. The source it is credited to (an archive, a broadcast, an unpublished sermon) is not public, so it cannot be checked directly.

Church Fathers & early medieval
354 to 800Augustine of Hippo
354 to 430 A.D.Fake · MisattributedAs quoted in the bookAll my hope, and the certainty of my faith, is in the precious blood of Christ, which was shed for us and for our salvation.
This is an incorrectly attributed quote. The misinformation stems from Alphonsus Liguori, a Catholic Saint and Italian Bishop of the Roman Catholic Church, who said in his Prayer: The Great Means of Salvation and of Perfection:
“But St. Augustine had no doubt when he said, ‘All my hope, and the certainty of my faith, is in the Precious Blood of Christ, Which was shed for us and for our salvation.’ Thus the Saint placed all his hope in the Blood of Jesus Christ; because the faith assured him that Christ died for all.”Alphonsus Liguori, Prayer: The Great Means of Salvation and of Perfection
Gennadius of Massilia
c. 495 A.D.FakeAs quoted in the bookChrist died once for all. The faith which saves is faith in His blood. This cannot be earned, nor bought, nor repeated in the Mass, but only believed and received.Cited as De Ecclesiasticis Dogmatibus, Chapter 45.
Chapter 45 of De Ecclesiasticis Dogmatibus is about free will and grace. It does not say what Breaker says it does.
If anyone contends that some can come to the grace of baptism by mercy, and others by free will, which, in all who are born of the first man’s transgression, is shown to be vitiated, he is proved to be alien to the right faith. For he does not assert that the free will of all was weakened by the sin of the first man; or at least he thinks it so impaired that some can nevertheless, without the revelation of God, by their own efforts seek out the ministry of eternal salvation. How contrary this is, the Lord himself proves (John 6:44), who testifies that not some, but no one can come to him, unless the Father has drawn him. As he also says to Peter: “Blessed are you, Simon son of Jonah, for this was not revealed to you by flesh and blood, but by my Father in heaven” (Matthew 16:17). And the Apostle: No one can say, “Lord Jesus,” except in the Holy Spirit (1 Cor. 12:3).Gennadius, De Ecclesiasticis Dogmatibus 45 (English translation)
Original Latin
Si quis alios per misericordiam, alios vero per liberum arbitrium, quod in omnibus qui de praevaricatione primi hominis nati sunt constat esse vitiatum, ad gratiam baptismi posse venire contendit, a recta fide probatur alienus. Ille enim non omnium liberum arbitrium per peccatum primi hominis asserit infirmatum; aut certe ita laesum putat, ut tamen quidam valeant sine revelatione Dei ministerium salutis aeternae per semetipsos posse conquirere. Quod quam sit contrarium ipse Dominus probat (Joan. VI, 44), qui non aliquos, sed neminem ad se posse venire testatur, nisi quem Pater attraxerit. Sicut et Petro dicit: Beatus es, Simon Bar Jona, quia caro et sanguis non revelavit tibi, sed Pater meus, qui in coelis est (Matth. XVI, 17). Et Apostolus: Nemo potest dicere Dominus Jesus, nisi in Spiritu sancto (I Cor. XII, 3).
Cassiodorus
Italy, c. 510 A.D.FakeAs quoted in the bookWe are reconciled to God by the blood of His Son, not by merit. Let the sinner trust in that blood, and not despair. It is not fasting or relics, but faith in the blood which saves.Cited as Explanation of the Psalms, Vol. 1, Psalm 51.
Cassiodorus: Explanation of the Psalms Vol. 1 only contains Psalms 1 to 50 (which is actually 51). Volume 2 contains 51 (which actually starts with 52) to 100, and Volume 3 contains 101 to 150. The Vulgate and Septuagint use a numbering system which is offset one number from the Hebrew Masoretic ordering.
Giving this the benefit of the doubt, let’s assume the quote only rejects the Catholic ordering. His commentary in Volume 1 on the book’s Psalm 50 (which is actually 51) contains no such passage.
And assume for the sake of argument it is actually the Catholic ordering, and it’s the Hebrew Masoretic Psalm 52:
- You can more or less see every page describing his commentary on Psalm 52, and it says nothing of the kind.
- Why would he mention the blood in a verse about God’s judgment on Doeg the Edomite?
Cassiodorus is used as one of the first people to mention the Catholic relic of the crown of thorns, making it highly illogical he would be against relics.
Gregory the Great
c. 600 A.D.FakeAs quoted in the bookChrist gave His blood for us. In that blood is remission, and by that blood we are made clean, if we believe. Not the ceremonies of men, but faith in His sacrifice is the true approach to God.Cited as Homilies on the Gospels, Book 1, Homily 21.
This line does not exist in the homily.
Gregory the Great is Pope Gregory I.
Isidore of Seville
Spain, c. 615 A.D.FakeAs quoted in the bookThe blood of Christ is the price of redemption. Faith in that blood cleanses from sin, justifies the sinner, and delivers from judgment. It is not by our efforts but by believing in His offering.Cited as Sententiae, Book 2, Chapter 16.
Cannot be found in the Sententiae.
Bede the Venerable
England, c. 730 A.D.FakeAs quoted in the bookThe blood of Christ cries out for mercy… And those who believe in that blood shall find peace with God. The cross is the altar, and the faithful are justified through trust in the sacrifice made there.Cited as Commentary on 1 Pet. 1:2.
Bede’s actual commentary on 1 Peter 1:2 says nothing like this. It speaks of election, sanctification by the Spirit, and sprinkling with the blood after the pattern of the Passover lamb.
According to the foreknowledge of God the Father, etc. These verses are joined to what he had said before: “to the elect strangers.” For they were elect according to the foreknowledge of God the Father. Hence the apostle says: ‘Whom he foreknew he also predestined to be conformed to the image of his Son.’ And elsewhere: As he chose us in him before the foundation of the world. The elect, however, were chosen for this purpose, that through the gift of the Holy Spirit they should be sanctified, cleansed from all sins, so that they, who had perished through the disobedience of the first-formed man, might begin to obey the Lord Jesus Christ, and that, sprinkled with his blood, they might avoid the power of Satan, just as Israel, by the blood of the lamb, cast off the dominion of the Egyptians. He speaks of sprinkling, however, in the manner of the Old Testament, where those things that were to be sanctified were accustomed to be sprinkled with the blood of sacrifices. Moreover, the Lord himself speaks plainly of it: ‘Unless you have eaten…’Bede, Super Epistolas Catholicas, on 1 Peter 1:2 (translated with DeepL, lightly corrected)
Original Latin
Secundum praescientiam Dei Patris, etc. Adhaerent hi versiculi ad hoc quod praedixerat, Electis advenis. Electi namque erant secundum praescientiam Dei Patris. Unde et apostolus ait: Quos praescivit et praedestinavit conformes fieri imaginis Filii sui. Et alibi: Sicut elegit nos in ipso ante mundi constitutionem. Electi autem erant ad hoc, ut per donationem Spiritus sancti sanctificarentur, emundati ab omnibus peccatis, ut obedire inciperent Domino Jesu Christo, qui per inobedientiam protoplasti perierant, ut aspersi sanguine ejus potestatem Satanae vitarent, sicut Israel per agni sanguinem Aegyptorum dominatum declinavit. Aspersionem autem dicit more Scripturae veteris, ubi quae sanctificanda erant, sanguine hostiarum solebant aspergi. Caeterum ipse Dominus dicit manifeste de eo: Nisi manducaveritis…
Alcuin of York
England, c. 790 A.D.FakeAs quoted in the bookLet no man trust in works or pilgrimages for salvation. Let him believe in the crucified One, whose blood is the only ransom. Blessed is the man who dies believing in that blood.Cited as Epistles, Letter 23 to Osbert.
This does not exist.
The Paulicians
Eastern Europe, 7th to 11th centuriesFakeAs quoted in the bookWe are justified not by works, nor by prayers to saints, nor by images, but by the blood of Christ shed once for all. And by faith we receive that blood, and are made whole.Cited as Quoted in Armenian chroniclers, Key of Truth, translated by F.C. Conybeare, 1898.
Conybeare’s 1898 English translation of The Key of Truth was fully searched through. The sentence is not in it, and neither are its distinctive phrases: “justified not by works,” “prayers to saints,” “shed once for all,” “receive that blood” and “made whole” do not appear.
- The citation is wrong. The Key of Truth is not a chronicle. It is an anonymous Paulician manual, which Conybeare published as A Manual of the Paulician Church of Armenia. The “Armenian chroniclers” are the medieval churchmen Conybeare quotes in his introduction and appendices, and most of them were hostile to the Paulicians.
- The real text teaches something different. It names four things that save, and baptism and the body and blood of the Lord’s Supper are two of them.
“Four are they which save man. First, Repentance. Second, Right Faith. Third, Holy Baptism.… And fourth, the holy precious body and blood of our Lord Jesus Christ.”The Key of Truth, trans. F.C. Conybeare (Oxford, 1898), Catechism
High medieval
820 to 1050Theodulf of Orléans
France, c. 820 A.D.FakeAs quoted in the bookThe Lord’s body was given, His blood was shed, and faith in this alone cleanses the soul. Not the offerings of the Mass, but the believing heart that lays hold of the blood.Cited as Homilies, Manuscript Vaticanus 105.
This citation is physically impossible. There is no such Manuscript Vaticanus 105.
Ælfric of Eynsham
England, c. 995 A.D.FakeAs quoted in the bookChrist’s sacrifice is not to be repeated. His blood was shed once for all, and we believe that we are redeemed by that offering. It is faith, not bread, that makes us clean.Cited as Sermon on the Easter Sacrifice, Old English Homily Series.
This passage does not exist in Volume 1 or 2 of The Homilies of the Anglo-Saxon Church by Ælfric.
Heriger of Lobbes
Belgium, c. 1000 A.D.FakeAs quoted in the bookIt is the heart that believes, not the hand that holds. The blood of the Lord is applied by faith, not by the senses, and the altar is not in the church, but in the soul.Cited as Commentary on the Gospels, Homily for Hebrews 9.
This book does not exist, and the citation contradicts itself: why would it be a commentary on the gospels, yet be a homily for Hebrews?
Fulbert of Chartres
France, c. 1025 A.D.FakeAs quoted in the bookJesus Christ is the Lamb, and His blood is the cleansing for our sins. We approach not by ritual alone, but by faith in His wounds, for in them is peace and reconciliation.Cited as Sermon in Passione Domini.
He has 9 surviving sermons, and this is not one of them. He also taught the real presence.
“But Fulbert adhered to the traditional orthodoxy, and expressed himself against innovations, in letters to his metropolitan, Leutberich, archbishop of Sens. He regarded the real presence as an object of faith and adoration rather than of curious speculation, but thought that it is not more difficult to believe in a transformation of substance by Divine power than in the creation of substance. He was a zealous worshipper of the saints, especially of the Virgin Mary, and one of the first who celebrated the festival of her Nativity.”Philip Schaff, History of the Christian Church, Vol. 4
Berengar of Tours
c. 1050 A.D.FakeAs quoted in the bookThe bread remains bread, and the wine remains wine; the body of Christ is not broken anew. We are not saved by the Mass, but by the blood of Christ shed once for all, and believed upon by faith.Cited as Quoted in Anti-Berengarian Documents, Roman opposition archives. The book adds: “Berengar was condemned for rejecting transubstantiation and affirming salvation through faith in Christ alone.”
This quote does not exist. These archives do not exist. He did deny transubstantiation, but I cannot find anything on sola fide.
The Council of Vercelli
1050 A.D.FakeAs quoted in the bookHe holds that the bread remains bread and that faith in Christ’s death and blood alone is sufficient to justify.Cited as Council Records, Vercelli Synod, quoted in Mansi’s Sacrorum Conciliorum Nova et Amplissima Collectio, Vol. 19. The book introduces it: “In condemning Berengar, they inadvertently recorded his faith.”
This does not exist in Mansi, Vol. 19.
The Bogomils
Balkans, 10th to 13th centuriesFakeAs quoted in the bookWe reject the Mass and the cross as idols, but we believe in the death of Jesus Christ and in His blood shed for sinners. The true altar is the heart that believes in the Lamb.Cited as The Secret Book of the Bogomils, quoted in Emmanuel d’Hooghvorst’s analysis, 1991.
“Baron Emmanuel van der Linden d’Hooghvorst (1914–1999) was a Belgian writer, spagyric philosopher and alchemist.”
- d’Hooghvorst did not publish any books in 1991, and he believed in Kabbalism. Why would he write on the Bogomils?
- The citation is illogical on further analysis: why would you quote him instead of just quoting the primary source?
- The Secret Book of the Bogomils does not have this line.
Dissenters & martyrs
1140 to 1568Peter de Bruys
Preacher, burned at the stake, c. 1140FakeAs quoted in the bookChrist’s sacrifice upon the cross is alone sufficient for the salvation of believers; and that sacrifice is not repeated in the Mass, nor applied through priests, but is received by faith in the blood.Cited as Recorded by Peter of Cluny, Contra Petrobrusianos, 1145.
I’ve looked at Contra Petrobrusianos. It doesn’t say this.
The Waldensians
Public testimony, 1165 A.D.FakeAs quoted in the bookWe do not believe that the body of Christ is made in the Mass; we believe that the bread remains bread and is only a memorial. We believe that it is the blood of Christ which cleanses us, by faith.Cited as Waldensian Statement at the Synod of Lombardy, 1165 A.D.
This line does not exist. Compare the genuine early Waldensian documents listed in the Sources, including the Letter from the Poor Lombards to the Poor of Lyons (1218).
The Albigenses
Southern France, 12th to 13th centuriesFakeAs quoted in the bookChrist died once, and that death is the only redemption for sin. We do not believe that the priest creates Christ in the Mass. We believe we are forgiven through faith in His blood.Cited as Doctrinal summary cited by Inquisitor Bernard Gui, Practica Inquisitionis Heretice Pravitatis, 1323.
This quote does not exist in the book, and the book was written in 1321, not 1323.
The Lollards
England, 14th to 15th centuriesFakeAs quoted in the bookIt is not the priest’s words that save us, but the blood of Christ. We believe that every faithful man is a priest by faith, and he is justified not by shrift but by trust in the blood of Jesus.Cited as Lollard Articles of Faith, Trial Records, London, 1410.
This does not exist, on several levels:
- 1410 is when John Badby was executed, so why would it be the group’s articles of faith when the trial was of a single person?
- It cannot be found.
The Lollards’ actual public statement of belief is The Twelve Conclusions of the Lollards, presented to Parliament in 1395, and nothing like this appears in it.
Francisco de San Román
Protestant martyr in Spain, 1540FakeAs quoted in the bookI believe only in the sacrifice of Jesus Christ, once offered on the cross, and not in the Mass. I believe in salvation through faith in His blood alone. For this I am content to die.Cited as Final testimony before being burned alive at the stake.
This quote does not exist.
George Wishart
Scottish Reformer, burned 1546FakeAs quoted in the bookThere is no salvation in the Pope. I believe salvation is in Christ, and in His blood alone. I fear not death, for I am washed in the blood of the Lamb.Cited as Final declaration before execution by Roman authorities. From Reformation Martyrs of Scotland.
There is no book called Reformation Martyrs of Scotland.
Wishart’s recorded words at the stake are nothing like this. He never mentions the Pope, “blood alone,” or being “washed in the blood of the Lamb.”
Antonio Herrezuelo
Martyr of Valladolid, 1559FakeAs quoted in the bookI have committed no crime, but have trusted in Christ alone for salvation. Let the flames bear witness that I reject the Mass and all its idols, and that I trust in the blood of Christ alone.Cited as Eyewitness account of his final words as he was burned alive. Historical source: “Spanish Protestant Martyrs,” compiled by Leonard Verduin.
- The book does not exist. Leonard Verduin never wrote a book called Spanish Protestant Martyrs.
- Herrezuelo is recorded as having been gagged the whole time he burned. A man who was gagged could not have given these final words.
Leonor de Cisneros
Burned 1568FakeAs quoted in the bookI denied the Lord once, but I will not deny Him again. Christ died for me, and I am saved by His blood, not by the Mass, not by confession to a priest. Let them kill me.Cited as Statement upon voluntarily returning to the Inquisition for martyrdom.
The book gives no source, and no account of her life records any statement by her, at her trial or at the stake. The only place these words appear is Breaker’s book.
Leonor, Herrezuelo’s wife, recanted in 1559 and was sentenced to three years’ imprisonment in a Benedictine monastery. After her husband’s death she returned to her Protestant faith and openly spoke about it among the other prisoners. She was condemned as a relapsed heretic and burned at Valladolid on September 26, 1568. So she did not walk back into the Inquisition from outside, as the book’s framing suggests.
Her story is well documented, and nowhere in it does she say anything like this. A 16th-century martyr’s words that first appear in a book published in 2025, with no source, have no historical basis.
Revivalists & modern preachers
1734 to 1977Jonathan Edwards
1703 to 1758, New EnglandFakeAs quoted in the bookIt is by faith in the blood of Christ that sinners are justified. The blood is the price, the ransom, the satisfaction. And faith is the hand that receives the atonement. The blood does not save automatically; it must be applied. And that is the office of faith: to lay hold of the blood and plead it before the throne.Cited as Justification by Faith Alone, sermon preached in 1734.
The full text of Justification by Faith Alone (dated November 1734) was checked word for word. None of these sentences appear in it. The phrases “lay hold of the blood,” “plead it before the throne,” and “does not save automatically” are absent, and the word “ransom” does not appear anywhere in the discourse.
The nearest real line is about faith in general, not about blood: faith is “the instrument, or as it were the hand, by which he that has purchased justification is apprehended and accepted.”
“Therefore the Scripture seems everywhere to attribute the whole of salvation to the blood of Christ. This precious blood is as much the main price by which heaven is purchased, as it is the main price by which we are redeemed from hell.”Jonathan Edwards, Justification by Faith Alone (1734/1738)
Charles H. Spurgeon
1834 to 1892Only source is Robert BreakerAs quoted in the bookIf our sins outnumbered the number of the hairs on our head; yet the merits of the death of Jesus Christ are infinitely greater, and faith in His blood shall make them white as snow.Cited as No citation given.
The book gives no source, and searches for the line, including “faith in His blood shall make them white as snow,” return nothing in Spurgeon’s sermons or anywhere else.
Billy Sunday
1862 to 1935, evangelistFakeAs quoted in the bookWhen Jesus Christ shed His blood on the cross, that was the payment for sin. But it won’t do you any good until you believe in it. The devil believes Jesus died, but he’s not saved. You have to have faith in that blood. If you trust that, God will save you. If you don’t, you’re lost forever.Cited as Quoted in The Evangelist’s Sermons, Billy Sunday, Fleming H. Revell Company, 1914, p. 193.
- No book called The Evangelist’s Sermons exists.
- The only Billy Sunday book Revell published in 1914 is Elijah P. Brown’s The Real Billy Sunday, a biography. Its page 193 is a newspaper report of Sunday’s South Bend revival (“Six thousand three hundred and ninety-eight persons have taken Billy Sunday by the hand”). It says nothing about the blood.
E.J. Pace
1879 to 1946FakeAs quoted in the bookWhat can wash away my sin? Nothing but the blood of Jesus. And how is that blood applied? Through faith! The gospel is not that Jesus lived, but that He died and shed His blood, and we must trust that blood to be cleansed. Romans 3:25 settles the issue. Without faith in the blood, you are still in your sins.Cited as From an unpublished sermon illustration in The Fundamentals, Vol. 3, Testimony Publishing, 1910. The book describes him as a “Baptist Illustrator, Bible Teacher and Theologian.”
- The citation contradicts itself. A sermon illustration cannot be both “unpublished” and printed in The Fundamentals.
- Pace did not write for The Fundamentals. Volume 3 (1910) contains essays by Gray, Moorehead, Speer, Mullins, Whitelaw, Reeve and Studd.
- In 1910 Pace was a missionary in the Philippines (1905 to 1915). His cartoons first appeared in The Sunday School Times on December 2, 1916.
- He was not a Baptist. He was an ordained United Brethren minister.
- The opening lines are Robert Lowry’s hymn “Nothing But the Blood.”
Bob Jones Sr.
1883 to 1968Only source is Robert BreakerAs quoted in the bookI believe in the old-time religion, the kind that preaches faith in the blood. I don’t care what the modernists say: God demands blood. And you better not trust your works, your feelings, your religion; you better trust the blood! That’s what Romans 3:25 says. You’ve got to have faith in that blood.Cited as Sermon transcript, “The Blood Still Saves,” Bob Jones Sr., 1943 Chapel Message, Bob Jones University Archives.
No sermon by this title can be found, and searches for the quote’s wording return nothing.
R.G. Lee
1886 to 1978, Baptist pastorOnly source is Robert BreakerAs quoted in the bookWithout the shedding of blood there is no remission. But without faith in that blood, there is no application of it. Romans 3:25 says it: faith in His blood. The blood of Christ is powerful enough to save the worst sinner, but it must be believed on. You can’t ride the coattails of religion. You’ve got to trust the blood for yourself.Cited as Sermon: “The Blood of Christ,” R.G. Lee, Bellevue Baptist Archives, preached 1951.
Neither this sermon nor this quotation can be found. Searches for its most distinctive line, “You can’t ride the coattails of religion,” return nothing.
B.R. Lakin
1901 to 1984, evangelistOnly source is Robert BreakerAs quoted in the bookWe are not justified by church membership, good behavior, or a clean past. We are justified by one thing: faith in His blood. When the Lord passed over Egypt, He wasn’t looking for goodness; He was looking for blood. And it had to be applied. So it is now. Jesus shed it, but you must trust it. You must rest your soul in it.Cited as Sermon: “The Only Way,” B.R. Lakin Crusade, 1955.
No sermon by this title can be found, and searches for the quote’s wording return nothing. Lakin began full-time evangelism in 1952, so a 1955 crusade is possible.
Carl McIntire
1906 to 2002Only source is Robert BreakerAs quoted in the book[T]he cross is not just an emblem; it is the altar of blood. And that blood is not a token or symbol. It is the real payment for sin. But hear me now: that payment is not applied unless it is received by faith. Romans 3:25 tells us how: ‘through faith in His blood.’ You can know the facts, believe the stories, and sing the hymns, but if you have not put your personal faith in the shed blood of Jesus Christ, you are lost.Cited as 20th-Century Reformation Hour Broadcast, Transcript, June 14, 1968.
The broadcast was real and aired daily, but no transcript for this date can be found, and searches for the quote’s wording return nothing.
W.A. Criswell
1909 to 2002, Southern BaptistOnly source is Robert BreakerAs quoted in the bookThere is no salvation apart from the blood of Christ, and that blood must be received by faith. You can be religious and be lost. You can be reformed and be lost. But if you put your faith in the blood of Jesus that was shed for your sins, you will be saved, forever! Romans 3:25 tells us it is by ‘faith in His blood.’Cited as Expository Sermons on Romans, W.A. Criswell, Zondervan, 1961, pp. 87–88.
No Criswell book on Romans from Zondervan in 1961 can be found, and searches for the quote’s wording return nothing.
Ian Paisley
1926 to 2014Only source is Robert BreakerAs quoted in the bookThere is no other way to God but by the blood, and no other way to appropriate that blood but by faith. This modern gospel of good works and religious excitement is a devil’s gospel. Romans 3:25 is crystal clear: God set forth His Son to be a propitiation through faith in His blood. Don’t trust your tears, your zeal, or your commitment; trust the blood!Cited as Sermon: “The Blood of the Everlasting Covenant,” Martyrs Memorial Free Presbyterian Church, 1977.
No Paisley sermon by this title can be found, and searches for the quote’s wording return nothing.
Almost every 20th-century quotation in this chapter cites Romans 3:25 by name. Bob Jones Sr., R.G. Lee, Carl McIntire, W.A. Criswell, Ian Paisley and the E.J. Pace entry all do. These men came from different denominations and different decades, yet each one leans on the exact verse Breaker builds his doctrine on.
That is what a chatbot produces when it is asked for quotes supporting “faith in His blood.”
