Thomas Aquinas

“ Accordingly all that is in things created by God, whether it be contingent or necessary, is subject to the eternal law: while things pertaining to the Divine Nature or Essence are not subject to the eternal law, but are the eternal law itself. ”

“ Although each one knows the eternal law according to his own capacity, in the way explained above, yet none can comprehend it: for it cannot be made perfectly known by its effects. Therefore it does not follow that anyone who knows the eternal law in the way aforesaid, knows also the whole order of things, whereby they are most orderly. ”

“ But in the good both ways are found more perfect: because in them, besides the natural knowledge of good, there is the added knowledge of faith and wisdom; and again, besides the natural inclination to good, there is the added motive of grace and virtue. ”

“ A thing is maintained in the end and moved towards the end by one and the same cause: thus gravity which makes a heavy body rest in the lower place is also the cause of its being moved thither. We therefore reply that as it is according to the eternal law that some deserve happiness, others unhappiness, so is it by the eternal law that some are maintained in a happy state, others in an unhappy state. Accordingly both the blessed and the damned are under the eternal law. ”

“ Irrational creatures neither partake of nor are obedient to human reason: whereas they do partake of the Divine Reason by obeying it; because the power of Divine Reason extends over more things than human reason does. And as the members of the human body are moved at the command of reason, and yet do not partake of reason, since they have no apprehension subordinate to reason; so too irrational creatures are moved by God, without, on that account, being rational. ”

“ Wherefore as the type of the Divine Wisdom, inasmuch as by It all things are created, has the character of art, exemplar or idea; so the type of Divine Wisdom, as moving all things to their due end, bears the character of law. Accordingly the eternal law is nothing else than the type of Divine Wisdom, as directing all actions and movements. ”

“ Nor does it follow that the eternal law is a Personal name in God: yet it is appropriated to the Son, on account of the kinship between type and word.
Reply to Objection 3: The types of the Divine intellect do not stand in the same relation to things, as the types of the human intellect. For the human intellect is measured by things, so that a human concept is not true by reason of itself, but by reason of its being consonant with things, since "an opinion is true or false according as it answers to the reality." ”

“ Both ways, however, are imperfect, and to a certain extent destroyed, in the wicked; because in them the natural inclination to virtue is corrupted by vicious habits, and, moreover, the natural knowledge of good is darkened by passions and habits of sin. ”

“ In this way the spiritual man is not under the law, because he fulfils the law willingly, through charity which is poured into his heart by the Holy Ghost. Secondly, it can be understood as meaning that the works of a man, who is led by the Holy Ghost, are the works of the Holy Ghost rather than his own. ”

“ Now wherever there are movers ordained to one another, the power of the second mover must needs be derived from the power of the first mover; since the second mover does not move except in so far as it is moved by the first. ”

“ Now just as man, by such pronouncement, impresses a kind of inward principle of action on the man that is subject to him, so God imprints on the whole of nature the principles of its proper actions. And so, in this way, God is said to command the whole of nature, according to Ps. ”
