Authority can mean different things to different people. For example, some document or other may be authoritative for particular group even though it's not reliable. It's just that the group has accepted that document as authoritative for their group. And some documents are truthful and reliable but they are ignored, so they have no authority for that particular group.
D. A. CarsonAll of us would be wiser if we would resolve never to put people down, except on our prayer lists.
D. A. CarsonSome Christians want enough of Christ to be identified with him but not enough to be seriously inconvenienced; they genuinely cling to basic Christian orthodoxy but do not want to engage in serious Bible study; they value moral probity, especially of the public sort, but do not engage in war against inner corruptions; they fret over the quality of the preacher's sermon but do not worry much over the quality of their own prayer life. Such Christians are content with mediocrity.
