You can have faith in "fidelity," which has existed in English since the 15th century; its etymological path winds back through Middle English and Middle French, eventually arriving at the Latin verb fidere, meaning "to trust." "Fidere" is also an ancestor of other English words associated with trust or faith, such as "fiduciary" (which means "of, relating to, or involving a confidence or trust" and is often used in the context of a monetary trust) and "confide" (meaning "to trust" or "to show trust by imparting secrets"). Nowadays "fidelity" is often used in reference to recording and broadcast devices, conveying the idea that a broadcast or recording is "faithful" to the live sound or picture that it reproduces.
