[T]he primary task of the Church is not to educate man, is not to heal him physically or psychologically, it is not to make him happy. I will go further; it is not even to make him good. These are things that accompany salvation; and when the Church performs her true task she does incidentally educate men and give them knowledge and information, she does bring them happiness, she does make them good and better than they were.
But my point is that those are not her primary objectives.
Her primary purpose is not any of these; it is rather to put man into right relationship with God, to reconcile man to God.
This really does need to be emphasised at the present time, because this, it sees to me, is the essence of the modern fallacy.
It has come into the Church and it is influencing the thinking of many in the Church—this notion that the business of the Church is to make people happy, or to integrate their lives, or to relieve their circumstances and improve their conditions. My whole case it that to do that is just to palliate the symptoms, to give temporary ease, and that it does not get beyond that.
I am not saying that it is a bad thing to palliate symptoms; it is not, and it is obviously right and good to do so. But I am constrained to say this, that though to palliate symptoms, or to relieve them, is not bad in and of itself, it can be bad, it can have a bad influence, and a bad effect, from the standpoint of the biblical understanding of man and his needs. It can become harmful in this way, that by palliating the symptoms you can conceal the real disease. . . .
The business of the Church, and the business of preaching—and she alone can do this—is to isolate the radical problems and to deal with them in a radical manner.
This is specialist work, it is the peculiar task of the Church.
The church is not one of a number of agencies, she is not in competition with the cults, she is not in competition with other religions, she is not in competition with the psychologists or any other agency, political or social or whatever it may chance to be.
The church is a special and a specialist institution and this is a work that she alone can perform.
