It is the thesis of this article that two basic kinds of structures make up the Christian movement. Most of the emphasis will be placed on pointing out the existence of these two structures as they have continuously appeared across the centuries. This will serve to define, illustrate and compare their nature and importance. The writer will also endeavor to explain why he believes our efforts today in any part of the world will be most effective only if both of these two structures are fully and properly involved. Finally, it is hoped that this material will highlight the degree of urgency to foster every effort to promote better understanding and harmony between these two structures.
