All things of human wisdom unite, and as it were center in this, that
there is one God, the Creator of the universe: consequently a man who
has reason, from the general nature of his understanding, does not and
cannot think otherwise. Say to any man of sound reason that there are
two Creators of the universe, and you will be sensible of his repugnance,
and this, perhaps, from the mere sound of the phrase in his ear; from
which it appears that all things of human reason unite and center in
this, that God is one. There are two reasons for this. First, the very
capacity to think rationally, viewed in itself, is not man's, but is
God's in man; upon this capacity human reason in its general nature
depends, and this general nature of reason causes man to see as from
himself that God is one. Secondly, by means of that capacity man either
is in the light of heaven, or he derives the generals of his thought
therefrom; and it is a universal of the light of heaven that God is one.
It is otherwise when man by that capacity has perverted the lower parts
of his understanding; such a man indeed is endowed with that capacity,
but by the twist given to these lower parts, he turns it contrariwise,
and thereby his reason becomes unsound.

24. Every man, even if unconsciously, thinks of a body of men as of one
man; therefore he instantly perceives what is meant when it is said that
a king is the head, and the subjects are the body, also that this or
that person has such a place in the general body, that is, in the kingdom.
As it is with the body politic, so is it with the body spiritual. The
body spiritual is the church; its head is God-Man; and from this it is
plain how the church thus viewed as a man would appear if instead of one
God, the Creator and Sustainer of the universe, several were thought of.
The church thus viewed would appear as one body with several heads; thus
not as a man, but as a monster. If it be said that these heads have one
essence, and that thus together they make one head, the only conception
