EnglishCafeteria ChristianA person who professes Christian adherence, but who selectively chooses which doctrines to follow.

This selection is often based on what's agreeable to secular society or what preserves a sensible ontology. For example, a self-identified Christian might be fine with homosexuality or pick an understanding of the Trinity from another sect. Done enough times, that might lead firmer Christians to refer to that behavior as "cafeteria Christianity".
