10. All sound reason, even when it is not religious, sees that every composite thing would of itself fall to pieces unless it depended upon some one thing; as in the case of man, composed of so many members, viscera, and organs of sensation and motion, unless they all depended on one soul; or the body itself, unless it depended on one heart. The same is true of a kingdom unless it depends on one king; a household, unless on one master; and every office, of which there are many kinds in every kingdom, unless on one officer. What would an army avail against the enemy unless it had a leader having supreme power, and officers subordinate to him, each of them having his proper command over the soldiers? So would it be with the church if it did not acknowledge one God, or with the angelic heaven, which is like a head to the church on earth, in both of which the Lord is the very soul. This is why heaven and the church are called His body; and when these do not acknowledge one God they are like a dead body, which being useless is carried away and buried.
