An Essay on the Development of Christian Doctrine

When an idea, whether real or not, is of a nature to arrest and possess the mind, it may be said to have life, that is, to live in the mind which is its recipient. Thus mathematical ideas, real as they are, can hardly properly be called living, at least ordinarily. But, when some great enunciation, whether true or false, about human nature, or present good, or government, or duty, or religion, is carried forward into the public throng of men and draws attention, then it is not merely received passively in this or that form into many minds, but it becomes an active principle within them, leading them to an ever-new contemplation of itself, to an application of it in various directions, and a propagation of it on every side. Such is the doctrine of the divine right of kings, or of the rights of man, or of the anti-social bearings of a priesthood, or utilitarianism, or free trade, or the duty of benevolent enterprises, or the philosophy of Zeno or Epicurus, doctrines which are of a nature to attract and influence, and have so far a primâ facie reality, that they may be looked at on many sides and strike various minds very variously. Let one such idea get possession of the popular mind, or the mind of any portion of the community, and it is not difficult to understand what will be the result. At first men will not fully realise what it is that moves them, and will express and explain themselves inadequately. There will be a general agitation of thought, and an action of mind upon mind. There will be a time of confusion, when conceptions and misconceptions are in conflict, and it is uncertain whether anything is to come of the idea at all, or which view of it is to get the start of the others. New lights will be brought to bear upon the original statements of the doctrine put forward; judgments and aspects will accumulate. After a while some definite teaching emerges; and, as time proceeds, one view will be modified or expanded by another, and then combined with a third; till the idea to which these various aspects belong, will be to each mind separately what at first it was only to all together. It will be surveyed too in its relation to other doctrines or facts, to other natural laws or established customs, to the varying circumstances of times and places, to other religions, polities, philosophies, as the case may be. How it stands affected towards other systems, how it affects them, how far it may be made to combine with them, how far it tolerates them, when it interferes with them, will be gradually wrought out. It will be interrogated and criticized by enemies, and defended by well-wishers. The multitude of opinions formed concerning it in these respects and many others will be collected, compared, sorted, sifted, selected, rejected, gradually attached to it, separated from it, in the minds of individuals and of the community. It will, in proportion to its native vigour and subtlety, introduce itself into the framework and details of social life, changing public opinion, and strengthening or undermining the foundations of established order. Thus in time it will have grown into an ethical code, or into a system of government, or into a theology, or into a ritual, according to its capabilities: and this body of thought, thus laboriously gained, will after all be little more than the proper representative of one idea, being in substance what that idea meant from the first, its complete image as seen in a combination of diversified aspects, with the suggestions and corrections of many minds, and the illustration of many experiences.

This process, whether it be longer or shorter in point of time, by which the aspects of an idea are brought into consistency and form, I call its development, being the germination and maturation of some truth or apparent truth on a large mental field. On the other hand this process will not be a development, unless the assemblage of aspects, which constitute its ultimate shape, really belongs to the idea from which they start. A republic, for instance, is not a development from a pure monarchy, though it may follow upon it; whereas the Greek "tyrant" may be considered as included in the idea of a democracy. Moreover a development will have this characteristic, that, its action being in the busy scene of human life, it cannot progress at all without cutting across, and thereby destroying or modifying and incorporating with itself existing modes of thinking and operating. The development then of an idea is not like an investigation worked out on paper, in which each successive advance is a pure evolution from a foregoing, but it is carried on through and by means of communities of men and their leaders and guides; and it employs their minds as its instruments, and depends upon them, while it uses them. And so, as regards existing opinions, principles, measures, and institutions of the community which it has invaded; it developes by establishing relations between itself and them; it employs itself, in giving them a new meaning and direction, in creating what may be called a jurisdiction over them, in throwing off whatever in them it cannot assimilate. It grows when it incorporates, and its identity is found, not in isolation, but in continuity and sovereignty. This it is that imparts to the history both of states and of religions, its specially turbulent and polemical character. Such is the explanation of the wranglings, whether of schools or of parliaments. It is the warfare of ideas under their various aspects striving for the mastery, each of them enterprising, engrossing, imperious, more or less incompatible with the rest, and rallying followers or rousing foes, according as it acts upon the faith, the prejudices, or the interest of parties or classes.

Moreover, an idea not only modifies, but is modified, or at least influenced, by the state of things in which it is carried out, and is dependent in various ways on the circumstances which surround it. Its development proceeds quickly or slowly, as it may be; the order of succession in its separate stages is variable; it shows differently in a small sphere of action and in an extended; it may be interrupted, retarded, mutilated, distorted, by external violence; it maybe enfeebled by the effort of ridding itself of domestic foes; it may be impeded and swayed or even absorbed by counter energetic ideas; it may be coloured by the received tone of thought into which it comes, or depraved by the intrusion of foreign principles, or at length shattered by the development of some original fault within it.

But whatever be the risk of corruption from intercourse with the world around, such a risk must be encountered if a great idea is duly to be understood, and much more if it is to be fully exhibited. It is elicited and expanded by trial, and battles into perfection and supremacy. Nor does it escape the collision of opinion even in its earlier years, nor does it remain truer to itself, and with a better claim to be considered one and the same, though externally protected from vicissitude and change. It is indeed sometimes said that the stream is clearest near the spring. Whatever use may fairly be made of this image, it does not apply to the history of a philosophy or belief, which on the contrary is more equable, and purer, and stronger, when its bed has become deep, and broad, and full. It necessarily rises out of an existing state of things, and for a time savours of the soil. Its vital element needs disengaging from what is foreign and temporary, and is employed in efforts after freedom which become wore vigorous and hopeful as its years increase. Its beginnings are no measure of its capabilities, nor of its scope. At first no one knows what it is, or what it is worth. It remains perhaps for a time quiescent; it tries, as it were, its limbs, and proves the ground under it, and feels its way. From time to time it makes essays which fail, and are in consequence abandoned. It seems in suspense which way to go; it wavers, and at length strikes out in one definite direction. In time it enters upon strange territory; points of controversy alter their bearing; parties rise and around it; dangers and hopes appear in new relations; and old principles reappear under new forms. It changes with them in order to remain the same. In a higher world it is otherwise, but here below to live is to change, and to be perfect is to have changed often.
