14 But it would be most repugnant to them to think thus of the wisdom and goodness of God. Even in physical things, albeit of a lower order, the Almighty has so combined the forces and springs of nature with tempered action and wondrous harmony that no one of them clashes with any other, and all of them most fitly and aptly work together for the great purpose of the universe. There must, accordingly, exist between these two powers a certain orderly connection, which may be compared to the union of the soul and body in man. The nature and scope of that connection can be determined only, as We have laid down, by having regard to the nature of each power, and by taking account of the relative excellence and nobleness of their purpose. One of the two has for its proximate and chief object the well-being of this mortal life; the other, the everlasting joys of heaven. Whatever, therefore in things human is of a sacred character, whatever belongs either of its own nature or by reason of the end to which it is referred, to the salvation of souls, or to the worship of God, is subject to the power and judgment of the Church. Whatever is to be ranged under the civil and political order is rightly subject to the civil authority. Jesus Christ has Himself given command that what is Caesar's is to be rendered to Caesar, and that what belongs to God is to be rendered to God.
