It’s a common definition amongst New Atheists that faith is merely belief without evidence. The occasional theist will accept this, often going further and purporting this to be some sort of virtue, but many Christians will reject this. They will argue that faith bears some relation to evidence, reason, logic, or even all three. But does that make sense? I don’t think so.
Let’s take the most populous religion in our culture: Christianity. If faith was more than belief without evidence, we should expect to find people with Christian beliefs that originated from somewhere other than the bible. That is, if faith is just a synonym for reason or logic or evidence, then a person ought to be able to discover all the information necessary to finding Christ.
Think about it. Calculus has been discovered at least 3 times (twice in Europe and once in Japan). The history of chemistry tells us certain elements have been found by several different people (usually with just one getting the credit). Atomic weapons have been created by multiple nations. All these things happen independently of each other. And why? Because math and science have methodologies behind them that progress on the basis of logic, reason, and evidence. Discoveries can repeat themselves in math and science. This is what we should expect of a type of inquiry that is more than belief without evidence.
When has faith produced the same result in independent people at independent times? Has anyone come to accept Christ in their hearts without the bible? Has anyone even come to know anything of Christ without the bible? Why is it that we don’t have any recorded instances of a Chinese person in, say, 80 A.D. writing about the Christian Savior? The answer is simple and obvious. It isn’t possible to discover anything offered on faith except through faith. To even know the name Jesus Christ, the original source of that name and of that man is always the bible; the original source is never found freely in the world, completely independent of the known Christian traditions. A tribesman in a remote part of the Amazon jungle will never know anything of what it means to be a Christian, no matter how hard he searches, less he find himself a victim of missionaries. Beliefs found on faith are beliefs without an evidential basis. Indeed, faith is nothing more than belief without evidence.
