Arguing dictionary definitions is so tedious.

That's just one of numerous definitions of the word, a historically legitimate definition to be sure. Sadly any innocent use of the word for that purpose is -- to my mind at least -- tainted by the other, socially dominant meaning.

And anyway, even using your cherry-picked definition, I still say I don't have faith in science, because I can't afford it "complete trust or confidence". While I do think the core principles of science are the best tools we have to describe the natural world, even these core principles can not be immune to questioning.
