belief, faith, credence, credit mean assent to the truth of something offered for acceptance. belief may or may not imply certitude in the believer <my belief that I had caught all the errors>. faith almost always implies certitude even where there is no evidence or proof <an unshakable faith in God>. credence suggests intellectual assent without implying anything about grounds for assent <a theory now given credence by scientists>. credit may imply assent on grounds other than direct proof <gave full credit to the statement of a reputable witness>.
