C.S. Lewis says that Doctrine and Theology is like a map that will be discarded in Heaven. "Now, Theology is like the map. Merely learning and thinking about the Christian doctrines, if you stop there, is less real and less exciting than the sort of thing my friend got in the desert. Doctrines are not God: they are only a kind of map. But that map is based on the experience of hundreds of people who really are in touch with God - experiences compared with which any thrills or pious feelings you and I are likely to get on our own are very elementary and very confused. And secondly, if you want to get any further, you must use the map. You see, what happened to that man in the desert may have been real, and was certainly exciting, but nothing comes of it. It leads nowhere. There is nothing to do about it. In fact, that is just why a vague religion - all about feeling God in nature, and so on - is so attractive. It is all thrills and no work: like watching the waves from the beach. But you will not get to Newfoundland by studying the Atlantic that way, and you will not get eternal life by simply feeling the presence of God in flowers or music. Neither will you get anywhere by looking at maps without going to sea. Nor will you be very safe if you go to sea without a map." - C.S. Lewis, Mere Christianity, Pg. 154 - 155 (HarperSanFrancisco Zondervan Publishing House)
Even newer theologians are saying the same thing.
Read what this little devil said in his book. "A final word about the use of slogans and doctrines. Anthony Lane rightly says that doctrines are maps and models, not mathematical formulas. We must avoid, then, relying on simplistic appeals to sola fide, or condemning without conversation or understanding those who reject the term. Instead, we must ask what those who reject sola fide intend when they question its adequacy. Perhaps those who reject it and those who affirm it are speaking past each other." - Thomas Schreiner, Faith Alone, Page 17 Is it true that those who hold to the simple belief of the gospel alone to save are just talking past each other with those who teach one is saved by Christ and something else?
Several questions come to mind when reading what Lewis wrote: How is theology less real, How do you know God? What exactly is a feeling? But, Gordon Clark, who was probably not thinking of Lewis at the time or perhaps he was, wrote on this subject about making theology only the map.
Gordon Clark says, "Passing on from Barth and Brunner we now come to Dr. George S. Hendry, Professor of Systematic Theology at Princeton Seminary. It is not so much his rejection of predestination and the atonement to which attention is here directed, as it is the non-Christian view of the nature of religion that underlies these rejections. In his book The Westminster Confession for Today Dr. Hendry writes,
Doctrines are not faith; they are statements of faith in propositional form. Faith has often been compared to a journey or a pilgrimage. Doctrine may then be compared to a map. No one would suppose he had reached his destination merely because he had located it on the map, or traced the route that leads to it. Yet the map is an indispensable aid to any traveler in unfamiliar country. And just as the map is right when it enables the traveler to reach the end of his journey, so doctrine is right when it enables the pilgrim to reach the end of his faith.
One should note that this analogy applies to the Bible itself as well as to the creeds, for the Bible also is written in sentences - propositions. When, therefore, Dr. Hendry in the next sentence says that doctrines are never 'infallible and irreformable,' his words apply as much to the Word of God as to the Confession. On these premises the Bible must itself be amended, and not simply the creeds where and if they inadequately reflect the Bible.
The analogy is attractive, but like all analogies it is misleading. Obviously a doctrine or a set of doctrines is not our ultimate destination, Heaven. But it does not follow that doctrine is merely a map. If an illustration is needed, let us say that doctrine is the road itself. If we change the doctrine, we change the road and head off in a wrong direction. Here we recall Luke's words to the effect that doctrine (that is, the propositions Luke wrote) is 'a declaration of those things which are most surely believed among us.'
In fact, this illustration of doctrine as map is so inept that even when corrected so as to make doctrine the road, it remains misleading. After we arrive at a destination, we not only throw away the map; we also cease using the road. But in Heaven we shall continue to believe these infallible and irreformable doctrines and learn many others, too. They will remain our precious possessions forever." - The Philosophy of Gordon H. Clark, Pg. 98
