Christ in that scientific formula:

If any man willeth to do His will, he shall know of the
teaching, whether it be of God, or whether I speak from
Myself.

To follow this formula in our search for common ground is to be utterly
scientific, for it is the laboratory method of experiment. The true Church
has always believed and received the Bible as the inerrant Word of God, not
because, in blind credulity, she has followed some irrational and
unscientific impulse, but precisely because she has been =scientific
enough= to work by this formula and carry the laboratory test to its =final
analysis=. And for the Schools to follow this same formula with scientific
accuracy would be for them to arrive at the same place at which the true
Church has arrived. For when the Church and the Schools start out in search
of truth and do not arrive together, it is either because they did not
start together, or because one or both of them did not proceed all the way
with scientific exactness. Truth is an eternal unity, and conclusions
regarding it that are mutually exclusive and therefore the cause of
controversy prove to a demonstration that somebody's methods of
investigation were unscientific.

If we really intend to be scientific, therefore, when we start out to
investigate truth of any sort and in any realm, the first thing we will do
will be to classify. We can neither start nor proceed together unless we
do. Indeed, if we are to be scientific enough to follow the formula laid
down by Christ, we will be compelled to classify before we can even begin
our investigation.

Therefore--

I. =Truth Must Be Classified Scientifically.=

1. The =Realms of Truth= Must Be Classified.

The first thing the true scientist does is to classify truth into realms.
This we have already done by classifying the realm in which God reveals His
moral character to the hearts of all moral beings as the =spiritual= realm,
and that in which He reveals His creative power to the minds of all
intelligent beings as the =natural= realm.

If we do not distinguish these realms to start with, we invite confusion;
and if we should reach right conclusions without this classification, it
would be due to accident, rather than to scientific accuracy.

But that this classification is universally recognized is proved by the
fact that the moment science reaches the line where the natural ends and
the spiritual begins, it pursues its investigations no far
