Such statements imply that science and religion are not that different because both seek the truth and use faith to find it. Indeed, science is often described as a kind of religion.

But that’s wrong, for the “faith” we have in science is completely different from the faith believers have in God and the dogmas of their creed. To see this, consider the following four statements:

“I have faith that, because I accept Jesus as my personal savior, I will join my friends and family in Heaven.”
“My faith tells me that the Messiah has not yet come, but will someday.”
“I have strep throat, but I have faith that this penicillin will clear it up.”
“I have faith that when I martyr myself for Allah, I will receive 72 virgins in Paradise.”
All of these use the word faith, but one uses it differently. The three religious claims (Christian, Jewish, and Muslim, respectively) represent faith as defined by philosopher Walter Kaufmann: “intense, usually confident, belief that is not based on evidence sufficient to command assent from every reasonable person.” Indeed, there is no evidence beyond revelation, authority, and scripture to support the religious claims above, and most of the world’s believers would reject at least one of them. To state it bluntly, such faith involves pretending to know things you don’t. Behind it is wish-thinking, as clearly expressed in Hebrews 11:1: “Now faith is the substance of things hoped for, the evidence of things not seen.”
