Hold firmly that our faith is identical with that of the ancients. Deny this, and you dissolve the unity of the Church.
— Thomas Aquinas

Few preachers of religion do believe thoroughly the doctrine of the Fall, or else they think that when Adam fell down he broke his little finger, and did not break his neck and ruin his race.
— Charles Spurgeon

The Spirit of God acts regularly; it works in and by the Word; and he that pretends to a new light, which is either above the Word, or contrary to it, abuses both himself and the Spirit...
— Thomas Watson

God gave me this great book to preach from, and if He has put anything in it you think is not fit, go and complain to Him, not to me. I am simply his servant, and if His errand that I am to tell is objectionable, I cannot help it. Let me tell you, the reason why many of our churches are declining is just because this doctrine has not been preached.
— Charles Spurgeon

Never forget that truth is more important to a church than peace.
— JC Ryle

Unity without the gospel is a worthless unity; it is the very unity of hell.
— JC Ryle

Doctrine is useless if it is not accompanied by a holy life. It is worse than useless; it does positive harm. Something of ‘the image of Christ’ must be seen and observed by others in our private life, and habits, and character, and doings.
— JC Ryle

I do verily believe that when God shall accomplish [unity], it will be the effect of love, and not the cause of love. It will proceed from love, before it brings forth love.
— John Owen

Is it our task to force the biblical doctrine of God to answer to modern culture, or (is it our task) to address modern culture with the biblical doctrine of God? If modern culture-or any culture-establishes the baseline for the doctrine of God, such a doctrine will certainly bear little resemblance to the God of the Bible.
— Albert Mohler

God’s family, which comes into being by regeneration, is more central and more lasting than the human family that comes into being by procreation.
— John Piper

The content of our faith is crucial. Sincerity is not sufficient.
— John MacArthur

If the Church is a living body united to the same head, governed by the same laws, and pervaded by the same Spirit, it is impossible that one part should be independent of all the rest.
— Charles Hodge

There is a hatred which is downright charity – that is the hatred of erroneous doctrine. There is an intolerance which is downright praiseworthy – that is the intolerance of false teaching in the pulpit.
— JC Ryle

God wants to give you His Spirit only through His external Word.
— Martin Luther

Scripture is the Holy Spirit’s school where everything we need to know is taught and where nothing is taught that is unneeded.
— John Calvin

We have come to a place in time where we measure the correctness of our plans simply by their seeming to contribute to our favorite aim. We estimate the soundness of our doctrine, not from its tendency to exalt and glorify God but entirely by the apparent facility with which it enables us to get sinners to turn from their ways.
— Horatius Bonar

If you wish to know God, you must know His Word. If you wish to perceive His power, you must see how He works by His Word. If you wish to know His purposes, before it comes to pass, you can only discover it by His Word.
— Charles Spurgeon

Learn to know what you mean when you talk of believing the doctrines of Christianity. Be able to give a reason of your hope. Be able to say what you think true, and what you think false in religion. And never, never forget that the only foundation of soundness of faith, is a thorough textual knowledge of the Bible.
— JC Ryle

The only way we can know God and His will is to have it given to us in a way that is unmistakable, and God has chosen to do that in a book, the Bible. ...and in that book he spoke, and what He said is exactly what He wanted to say and He desired to say it in a way that we would understand it...we are accountable for it.
— John MacArthur

Inability to distinguish doctrine is spreading far and wide, and so long as the preacher is “clever” and “earnest,” hundreds seem to think it must be all right, and call you dreadfully “narrow and uncharitable” if you hint that he is unsound!
— JC Ryle

Doctrinal preaching certainly bores the hypocrites; but it is only doctrinal preaching that will save Christ’s sheep.
— JI Packer

Those who teach by their doctrine must teach by their life, or else they pull down with one hand what they build up with the other.
— Matthew Henry

Like the doctrine of the Holy Trinity and the miraculous birth of our Savior, the truth of election must be received with simple, unquestioning faith.
— AW Pink

There are certain doctrines taught in Scripture quite clearly, but then we come up against something that we cannot quite fit into our doctrinal pattern, and the danger at that point is to stand on our own doctrine and to try to explain away the Scripture. If ever we find a point that seems to conflict with our clear grasp of doctrine, it seems to me that, for the time being, the essence of wisdom is to leave our doctrine where it is. It is not to deny it, we just leave it for the moment, we come back to Scripture and we note what Scripture has to say everywhere about this particular matter. Then having done that, we again attempt to relate this obvious and clear teaching of Scripture with the doctrine of which we are equally sure.
— Martin Lloyd-Jones

We should no more tolerate false doctrine that we would tolerate sin.
— JC Ryle

Doctrine is useless if it is not accompanied by a holy life. It is worse than useless; it does positive harm. Something of ‘the image of Christ’ must be seen and observed by others in our private life, and habits, and character, and doings.
— JC Ryle

Now, in order that true religion may shine upon us, we ought to hold that it must take its beginning from heavenly doctrine and that no one can get even the slightest taste of right and sound doctrine unless he be a pupil of Scripture.
— John Calvin

To preach the Gospel is to state every doctrine contained in God’s Word and to give every truth its proper prominence.
— Charles Spurgeon

People go wrong in their fellowships before they go wrong in their doctrine.
— John R Rice

Good conduct arises out of good doctrine.
— John Stott

The doctrines of grace humble man without degrading him and exalt him without inflating him.
— Charles Hodge

There is scarcely anything so dull and meaningless as Bible doctrine taught for its own sake. Truth divorced from life is not truth in its biblical sense, but something else and something less.
— AW Tozer

Compare Scripture with Scripture. False doctrines, like false witnesses, agree not among themselves.
— William Gurnall

Indeed, I disagree very much with those who are unwilling that Holy Scripture, translated into the vulgar tongue, be read by the uneducated, as if Christ taught such intricate doctrines that they could scarcely be understood by very few theologians, or as if the strength of the Christian religion consisted in men’s ignorance of it.
— Desiderius Erasmus

The Spirit and the Word must be combined. If I look to the Spirit alone without the Word, I lay myself open to great delusions.
— George Mueller

At the heart of our worship must be a commitment to truth
— RC Sproul

There is an inseparable relationship between your affection for Christ and you affection for the scriptures.
— RC Sproul

Doctrine matters. What you believe about God, the Gospel, the nature of man, and every major truth addressed in Scripture filters down to every area of your life.
— John MacArthur
