Now, we might well enlarge on these five important vital processes—discipleship, leadership, fellowship, service and growth. But my purpose will have been served if I have said enough to bring home to you the fact that these are the things that matter, the things that are of vital importance in the Church. Methods and machinery, organization and Church discipline have a value of their own, but only a subordinate value to these prime factors of health. If these lesser things are accepted as a substitute for the vital factors, the Church becomes weak. If they are allowed to limit the development of the life, the Church may become dwarfed and deadened. Their true function, the true function of organization and discipline and these other matters, is surely large enough—namely, to provide means with which and through which the life can readily work. IV. In vital Quakerism then, the form has continually to be subordinated to the life. The life must be allowed free expression from time to time and place to place according to the varying needs and circumstances. In a word, the form must be kept plastic. This should be as much a fundamental of religious biology as it is of physiology. The physiologist tells us that living matter is always soft and jelly-like. It is matter in a jelly-like state, permitting of the free play of molecular interchanges, so that it is called a “dynamical state of matter.” That is the general statement about living matter which the physiologist has to make to us to-day. It is essential that it should be plastic, able to grow, able to change its shape from time to time. It is always changing its form, as may be seen in the colorless cells of the blood. It has been said, and said truly, that no one of us is the same person we were seven years ago, every little bit of us has been changed in the interval. Living matter does not grow like the crystal, by the addition of new matter on its surfaces. It grows by absorbing matter into its substance and transforming that into matter like itself. It should surely be the same in the life of institutions. The form should be flexible so that the life may be continually growing and changing its form according to the great directing control which the life exerts upon the body, and you want ease and flexibility in organizations just as you do in clothes. If you do not have this, you will have a good deal of chafing and cramping. Sometimes, perhaps, a growing boy will burst his waistcoat. It is a great mistake to try to fit the man to the clothes when we ought to be fitting the clothes to the man, but it is a mistake that the Quaker Church has frequently made.
