Were it received as a principle, that love to the Lord and charity to
the neighbor are what the whole Law hangs on and are what all the
Prophets speak of, and thus are the essentials of all doctrine and
worship, then the mind would be enlightened in innumerable things in
the Word, which otherwise lie hidden in the obscurity of a false
principle. In fact, heresies would be scattered then, and out of many
one Church would come to be, however the doctrines flowing therefrom
or leading thereto, and the rituals, might differ. Were the case so,
all men would be governed as a single human being by the Lord; for all
would be as members and organs of one body, which, dissimilar in form
and function though they are, still have relation to one heart only,
whereon they each and all depend. Then, in whatever doctrine or
outward worship one might be, he would say of another, "This man is my
brother. I see that he worships the Lord, and that he is a good man."
