The Christian answer is that the faith being attacked is not the
faith anyone actually holds. The classical Christian tradition —
Augustine to Aquinas to the Catechism — has never defined
faith as believing without evidence, still less as believing
against it. Faith is a free assent of the mind, deepened
into trust in a person, and answered in a faithful life,
resting on grounds that are real though not compelling. That it
runs past proof is not its peculiar vice but the ordinary
condition of every thinking person, including the skeptic who
denies it.
Where the Objection Fails
The case against faith rests on a small confusion, and once it is named the argument does not recover. The former atheist Alister McGrath put his finger on it: the slogan fails to distinguish between the total absence of supporting evidence and the absence of totally supporting evidence. A belief can rest on real evidence that still falls short of proof, and nearly everything anyone believes is exactly like that. The critic’s definition quietly assumes that evidence either compels or is absent altogether, with nothing in between. Almost nothing we know is like that.1
You Cannot Prove Everything, and No One Does
Behind the demand “why believe anything you cannot prove?” lies a misunderstanding of proof. A proof reasons from things already accepted to something that follows. So every proof needs a starting point it does not itself prove. Demand a proof for those premises and you need premises for that proof, and so on without end. An endless chain of proofs is impossible.2
This is not a religious trick; it is how thinking works. The rules of logic cannot be proved, because you must use them to prove anything at all. That the world outside my mind is real, that my memory is not a wholesale fabrication: no one proves these before breakfast, and everyone stakes a life on them. The honest question is never whether to accept what cannot be proved, but which, and on what grounds.
What Faith Actually Is
The word carries three strands, and most of the confusion comes from crushing them into one. First assent: to believe is, in Augustine’s phrase, to think with assent, a free judgment that something is true, free precisely because the evidence, though real, does not force the hand. Second trust: the New Testament word, pistis, means reliance, the entrusting of oneself; its verb is less “to hold an opinion” than “to entrust oneself.” Third faithfulness: the same biblical words mean steady loyalty, said above all of God, “the faithful God who keeps covenant” (Deut. 7:9). Human faith answers that prior faithfulness. Put the three together and faith is confident trust in what one has good reason to hold true: “the assurance of things hoped for, the conviction of things not seen” (Heb. 11:1).3
Everyone Already Lives This Way
Belief, in the everyday sense, is a readiness to act as though something were so. Nobody lowers himself onto a chair he does not trust; you believe the friend who telephones to say the house is on fire. Science runs on the same fuel — it reasons from what it has seen to laws it cannot finish checking, and rests on a confidence no experiment can establish: that the universe is orderly and that our minds can grasp it.4
And unbelief is no exception. To disbelieve is a readiness to act as though something were false — as Dallas Willard put it, not acting is acting — and the critic’s own rule, that only what reason and evidence establish may be accepted, cannot itself be established by reason or evidence. He trusts that his mind is reliable, that the world is orderly, that logic holds, none of which he can demonstrate without already using them.5 This does not make the unbeliever wrong, but it levels the ground: believer and skeptic alike live by trust that runs past proof, and both are answerable for where they place it.
Faith Is Not Superstition
Superstition is the belief that some object or action not really connected to an outcome can force it anyway: that the right words will make someone love you, that the right dance will bring rain. Its heart is control: perform the rite correctly and events, even heaven, bend to your will. Christian faith is the reverse. It does not attempt to control God but to rely on Him, and Scripture itself condemns the attempt to buy or command divine power (Acts 8; 19).6
There is an irony here that cuts the other way. Consider the familiar demand: let God give me a sign, and then I will believe. It sounds hard-headed, but it is superstition in a lab coat, assuming God is a mechanism obliged to perform on cue if the right challenge is issued. Superstition tries to control; faith is content to rely. It is the sign-on-demand, not the believer’s trust, that falls on the wrong side of that line.
Neither Blind nor Unfalsifiable
Nowhere does Scripture hold up faith as belief against evidence. Christ appealed constantly to evidence (to His works, to eyewitnesses, to what was written; John 10:37–38; 20:24–29) and He reasoned, by analogy, by exposing contradictions, by driving an opponent’s premise to absurdity. If the Lord Himself argued from evidence, His followers can hardly claim His authority for discarding it.7
Nor is the faith unfalsifiable, whatever is said of individual believers. It stakes itself on a historical claim and says so in as many words: “if Christ has not been raised, then our preaching is in vain and your faith is in vain … we are of all men most to be pitied” (1 Cor. 15:14–19). That is a falsification condition, stated by the faith about itself. A creed that names the evidence which would destroy it is not the sort of thing the objection describes.8
One concession is owed. Fideism — the view that faith needs
no reasons and may even be prized for lacking them — is a real
position, and some believers hold it; Tertullian is quoted for it
(usually misquoted), and Kierkegaard came near it. But it is not
the Catholic position, and the Church has said the opposite in
council: the First Vatican Council taught that God “can be
known with certainty from the created world by the natural light of
human reason” (Dei Filius, ch. 2, quoted at CCC 36),
and that faith and reason can never truly contradict each other.
The critic who quotes Tertullian against the Church is quoting a
man the Church declined to follow.
Clifford’s Shipowner, and Freud’s Wish
The shipowner deserves a direct verdict, and the Catholic verdict
is: guilty as charged. The man had evidence — the
ship’s age, her build, his own troubled doubts — and
he smothered it because attending to it would cost him money.
That is not faith; it is the vice Scripture calls hardening the
heart, and a believer who keeps his belief by stifling honest
doubts is doing what the shipowner did. What the parable cannot
show is that trusting a credible witness is like ignoring a
rotten hull. The believer’s claim is that the witness has
been examined — a contingent world, the testimony of the
apostles, a Church that survived everything that should have
killed it — and found trustworthy: belief on evidence, of
the kind courts and historians act on daily. Clifford’s
maxim, meanwhile, fails its own test, for “it is wrong
always … to believe anything upon insufficient
evidence” is not itself a truth anyone can establish by
evidence; held strictly, it forbids believing Clifford. And where
evidence cannot decide and life will not wait, refusing to decide
is itself a decision — made on the same insufficiency.
Freud’s account asks a fair question — does the wish
father the belief? — and it proves nothing in either
direction, because a wish tells you about the wisher, not the
world: a drowning man’s longing for a rope is no evidence
there is none. And unbelief has its wishes too. Thomas Nagel, as
honest an atheist as philosophy has produced, has written
candidly that he hopes there is no God and would not
want the universe to be like that — a cosmic authority
problem, he calls it. If wish-fulfillment discredited belief, it
would discredit unbelief with the same stroke. The evidence has
to be weighed on its own, which is what the rest of this page
does.
Three Remaining Objections
A crutch for those who cannot face reality. Everyone leans on something in the dark hours (money, status, confidence in oneself) and all are more fragile than they look. Belief in oneself saves nobody from death or loss. To call faith a crutch is only to say one would rather lean on oneself than on God. That is a preference, not a proof. The question is not whether you lean, but on what.
The great source of violence and war. The record says otherwise. When Phillips and Axelrod catalogue the wars of recorded history in their three-volume Encyclopedia of Wars, of 1,763 wars fewer than 7 percent prove to have been primarily religious; remove those waged in the name of Islam and the figure falls to a little over 3 percent. The bloodiest century in history was dominated not by religion but by militant atheist regimes. The culprit is fanaticism, which fastens onto secular creeds as readily as sacred ones.9
The Bible praises believing without seeing. The verse (John 20:29) is spoken to Thomas, who has just been given the evidence, the risen Christ standing before him. The blessing falls on later disciples who, not seeing the risen Lord in person, believe on the trustworthy testimony of those who did. That is not credulity but the ordinary reliance on reliable witnesses by which we accept nearly everything we know about the past.
The Accident of Birth
One objection deserves more than a paragraph, because it is the strongest of them. Whatever reasons a believer gives, the best predictor of which God he worships is where he was born; and a faith held only because it was handed over is not held for any reason at all. The correlation is real, and a Christian who has never once examined what he was given ought to be unsettled by it.
But notice what the argument costs to run. Taken strictly it reaches every conviction a person has, and not only the religious ones. Confident secular naturalism is clustered by time and place as tightly as any creed — dense in Western Europe and the American university, effectively absent from most of recorded history, and no likelier to occur to a man born in Riyadh than Anglicanism is. A test that discredits every position on the map discredits none of them. Nor is there an outsider’s chair to sit in and judge from: the skepticism of the outsider is not a view from nowhere but a particular and recent stance with a family tree of its own, and stepping out of one tradition means stepping into another.10
Take the moderate version of the test, though, and the Church agrees without hesitation, because it is what she has always claimed to invite. Faith is never credited here for going unexamined. Natural theology, the preambles to faith, an apologetics addressed to people who are standing outside — the whole apparatus exists so that the claim can be weighed by someone who does not yet accept it. An inheritance that asks to be tested is not the same thing as a prejudice.
And the factual premise leaks. People change, in very large numbers, and the fastest Christian growth of the last century has been where the faith was not inherited from anybody. The writer of this page is a small instance of it: the child of non-religious parents, baptized a Baptist as a boy on his own initiative, baptized a Jehovah’s Witness at sixteen against his parents’ determined resistance, and received into the Catholic Church in 2013. That story is told in full in the account of his life before and after Bethel. Whatever else it is, it is not an accident of birth.
One more word, for the reader who has watched exactly what the
skeptic describes: a belief that survived every disappointment by
redefining itself, so that 1914 meant one thing, then another, and
“this generation” five things in turn. That is what
faith looks like when it has been made unfalsifiable, and the
skeptic is right to distrust it. It is not what the Church means by
faith. She stakes her claim on things that could have been
otherwise: an empty tomb, a resurrection Paul said would make the
faith “futile” if it had not happened (1 Cor.
15:17), a succession of bishops any historian can trace. A faith
that names the fact that would refute it is the opposite of the
faith you left.
The Reply in Brief
Nearly every version of the objection turns out to depend on the definition it began with. Grant that faith means believing things without reason, and the case against it is finished before it starts; withdraw that definition, and there is very little left to answer. But no one who actually holds the faith has ever meant that by the word, and a criticism that only defeats a meaning its target rejects has not reached its target.
What is really being asked is a question the critic must answer too: what may a reasonable person believe when the evidence is genuine but falls short of proof? Nobody escapes it. Every serious conviction about the world (including the conviction that there is nothing beyond it) is held on grounds that cannot be closed off, by someone who must decide anyway. The dispute is not whether to live past the evidence but what to live past it toward.11
This is the short answer. The full treatment adds the Catholic account of faith as gift before achievement and living response before settled possession, why faith without works is dead, the old image of faith as root with hope the stem and love the flower, doubt as faith’s companion rather than its enemy, Screwtape’s warning about the believer who “asks why he has been forsaken, and still obeys,” the cliff-and-branch parable and what it gets wrong, and full documentation for everything asserted here. It is available as a Word document at the end of this page.
