What do we mean by "science"? And what do we mean by "faith"? These questions are open for debate in Science And Faith Examined events. But our working definitions are these: 

By Science We Mean:

"Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe." - Wikipedia

By Faith We Mean: 

Faith is a mode of belief motivated by human experience and reason. Faith, like science, considers empirical evidence in its quest for knowledge about the universe, but it also considers personal, emotional, unique (miraculous), and communal human experience, along with insights derived from abstract philosophical reasoning in order to build its models of understanding (e.g. religions).

Retired Cambridge Physicist and Anglican Priest, John Polkinghorne, offers a helpful insight:

"Many people seem to think that faith involves shutting one's eyes, gritting one's teeth, and believing six impossible things before breakfast because the Bible or the Pope or some other questionable authority tells us so. Not at all! Faith may involve a leap, but it's a leap into the light, not into the dark. The aim of the religious quest, like that of the scientific quest, is to seek motivated belief about what is the case.... [faith] can only be of real value if it's actually true. It's not a technique for whistling in the dark to keep our spirits up."
