Most of us have been there. You are in a conversation with a skeptical friend or browsing a comment section when someone treats the Bible like a collection of poorly written fairy tales. They might tell you that faith is just a blind leap in the dark or that science has long ago buried the “myths” of the prophets. In those moments, it is easy for a Christian to feel a bit like they have brought a butter knife to a gunfight. We curiously wonder if our faith is based on anything more than a feeling we got at a summer camp years ago. Archibald Alexander, the legendary first professor at Princeton Seminary, wrote Evidences of the Authenticity, Inspiration, and Canonical Authority of the Holy Scriptures to show that you don’t have to check your brain at the church door.
As a pastor who stands firmly on the Westminster Standards, I find Alexander’s work to be an essential fortress. He doesn’t just ask us to “believe because we say so.” Instead, he invites the reader to look at the cold, hard facts of history, logic, and the human soul. This book is a manual for anyone who wants to move from a fragile “I hope this is true” to a sturdy “I know this is true.” Here are the most impactful takeaways from this classic defense of the Word of God.
Reason is the Eye, Not the Light
One of the most helpful points Alexander makes early on is the proper relationship between our brains and our Bibles. Many people think that religion is the enemy of reason. Alexander turns that on its head, arguing that without reason, there can be no religion at all. We use our reason to examine the evidence, to interpret the words, and to understand the doctrines.
However, reason is like an eye. It needs light to see, but it is not the light itself. We don’t use our reason to sit in judgment over God, telling Him what He is allowed to say. Instead, we use our reason to see if God has actually spoken. Once we are convinced that the Bible is His Word, the most “reasonable” thing we can do is believe everything it says, even the parts that are way beyond our tiny human understanding.
“Without reason there can be no religion: for in every step which we take, in examining the evidences of revelation, in interpreting its meaning, or in assenting to its doctrines, the exercise of this faculty is indispensable.”
The Volcano of No-Religion
Alexander addresses a relatable curiosity: what would happen if the skeptics actually won and banished all religion from the earth? Some imagine a peaceful world of pure science, but Alexander points to the “characters of blood” written during the French Revolution as a warning. He describes man as a “religious animal.” If you take away the true God, people don’t become neutral; they just find new, often more violent and absurd things to worship.
He argues that atheism has no “bond of union.” It breeds suspicion and selfishness because it removes the ultimate restraint of a future judgment. He notes that even the most famous atheists often turn into the most superstitious people when a storm hits at sea. Religion isn’t just a private hobby; it is the very thing that keeps a society from turning into a “picture of hell upon earth.”
“It is the BIBLE which has delivered us from the horrid dominion of superstition, and it is the BIBLE which must prevent its return. Philosophy has had no hand in working out this deliverance from the horrors of idolatry.”
The Fisherman Who Beat the Empire
A truly surprising takeaway is Alexander’s analysis of how the Gospel actually spread. If Christianity were an imposture, it was the worst-planned one in history. The first preachers were “few and feeble” instruments—mostly unlearned fishermen from a despised nation. They didn’t have money, they didn’t have armies, and they certainly didn’t have the “man-pleasing” doctrines that people usually want to hear.
Instead, they preached a crucified leader and told people they had to give up all their sins and be ready to die for the truth. Alexander reflects that if a few Jewish mechanics tried to proselytize the world today without any help, we would laugh. Yet, these men turned the most polished and powerful cities of the Roman Empire upside down. Alexander argues that this is a “standing miracle.” It is impossible to account for their success unless you admit that God was actually with them.
The Book That Knows Your Secrets
While history and miracles provide “external” proof, Alexander spends significant time on the “internal” evidence—the way the Bible actually feels when you read it. He calls it the “power over the conscience.” Have you ever noticed that the Bible is the only book that seems to read you while you are reading it? It doesn’t flatter us. It describes the human heart as “deceitful and desperately wicked,” a description that matches our experience perfectly.
Alexander reflects that this “sublime sanctity” is something impostors could never fake. Wicked men would never write a book that is so focused on holiness and so honest about human failure. This takeaway suggests that the best cure for doubt isn’t just a better argument; it is a serious, prayerful reading of the text itself. The Bible shines with a celestial light that proves its own origin to anyone who isn’t squinting their eyes shut.
“This new creation is not an improvement, or a mending of the old principles of nature, but an infusion of new ones, and so is properly styled a creation.”
Why You Should Read This Book
You should read Archibald Alexander’s Evidences of the Holy Scriptures because we live in a world that is loud with objections and thin on actual answers. This book is a tonic for the soul.
Whether you are a parent trying to answer a child’s tough questions, a student facing skepticism on campus, or a pastor looking to strengthen the flock, this book provides the “intellectual armor” you need. It reminds us that our faith is not a “cunningly devised fable,” but a sure word of prophecy that has been tested in the fires of time and found to be pure gold. If you have ever felt like your feet were on shifting sand, Alexander will help you find the Rock.
