We cannot tell how far the Christians can supply their own needs, if we do not know what the needs really are.

And that we do not know.

In a certain very real sense Christians can always provide what is necessary for their religious life.

They could all always be self-supporting, if we did not invent needs and insist upon them; and what we insist upon depends entirely upon the school in which we were brought up.

The standard set, as we have already explained, is purely arbitrary.
Under these circumstances how can we express the position of the native Church with any approximation to truth?
We can only suggest that these arbitrary standards should be accepted, and ask that they should be defined in every case.
