From the article:
[W]hat is true is that evolution tests faith. The fact of evolution is incontrovertible and supported by mounds of empirical evidence. Faith, on the other hand, is fragile. It is supported only by the strength of human will. And this is where it gets tricky. Because to many believers, faith, not works, is the only guarantee that one can pass God’s litmus test and gain access to His divine kingdom. To lose one’s faith is to literally damn oneself. So tests to that faith must be avoided at all costs. Better to be a philosophical coward than a theological failure.
