When someone says something in regards to, say, a fact of science, that ‘it strengthened their faith’, what exactly does that mean? That acquiring this particular piece of empirical knowledge somehow increased either the quality or quantity of their faith? How would this work? I see statements like that often, but I’m not sure what is really meant by them. One believes in God – does learning X mean that now they really believe in God? Or that if there was any doubt, now there isn’t? But suppose X hadn’t been found out. Would said faith be weaker than if X had? I doubt that very much – I have a hard time imagining a devout Christian would have their faith shaken by not coming across a certain fact – if they did, then that would serve simply to show the folly of basing one’s faith in God upon a particular empirical fact.
Or suppose that the opposite of X, Y, had been found out. Would that have weakened said faith? I doubt that, because I don’t think what is meant by ‘strengthening faith’ is that X actually increases the quality of one’s spiritual confidence in God, or corrects a deficiency or weakness in said faith, but rather that X simply affirms what is already believed. I know my wife is a lovely person, but when she makes a nice dinner or cleans up the kitchen, I don’t say, ‘wow, that really strengthened my belief that she’s a nice person.’ I already know she’s a nice person – dinner simply serves to confirm what I already know. A poor analogy that’s best not pressed too far, but it serves the point.
Anyway, my point is that I don’t think most folks who say that X strengthens their faith actually mean that. From a theological perspective, God strengthens my faith – not any particular empirical or metaphysical fact. I think it was Newman who said, ‘I believe in design because I believe in God, not in God because I believe in design.
