“A unity in diversity of actions”: - “each person cannot do everything and all persons cannot do the same thing”

An expansion of thought and action in certain aspects of our work would enhance our possibilities for success in meeting our aforementioned commitments. Since change, ever more rapid change, is a constant characteristic of life at this time, and since our growth, size and external relations demand much of us, our community must be ready to adapt. In a sense this means that the community must become more adept at accommodating a wide range of actions without losing concentration on the primary objectives of teaching, namely, expansion and consolidation. A unity in diversity of actions is called for, a condition in which different individuals will concentrate on different activities, appreciating the salutary effect of the aggregate on the growth and development of the Faith, because each person cannot do everything and all persons cannot do the same thing. This understanding is important to the maturity which, by the many demands being made upon it, the community is being forced to attain.
