On the contrary, Gregory says (Moral. vi, 37) that "in contemplation we seek the principle which is God."
I answer that, As stated above (A. 2), a thing may belong to the contemplative life in two ways: principally, and secondarily, or dispositively. That which belongs principally to the contemplative life is the contemplation of the divine truth, because this contemplation is the end of the whole human life. Hence Augustine says (De Trin. i, 8) that "the contemplation of God is promised us as being the goal of all our actions and the everlasting perfection of our joys." This contemplation will be perfect in the life to come, when we shall see God face to face, wherefore it will make us perfectly happy: whereas now the contemplation of the divine truth is competent to us imperfectly, namely "through a glass" and "in a dark manner" (1 Cor. 13:12). Hence it bestows on us a certain inchoate beatitude, which begins now and will be continued in the life to come; wherefore the Philosopher (Ethic. x, 7) places man's ultimate happiness in the contemplation of the supreme intelligible good.
Since, however, God's effects show us the way to the contemplation of God Himself, according to Rom. 1:20, "The invisible things of God . . . are clearly seen, being understood by the things that are made," it follows that the contemplation of the divine effects also belongs to the contemplative life, inasmuch as man is guided thereby to the knowledge of God. Hence Augustine says (De Vera Relig. xxix) that "in the study of creatures we must not exercise an empty and futile curiosity, but should make them the stepping-stone to things unperishable and everlasting."
Accordingly it is clear from what has been said (AA. 1, 2, 3) that four things pertain, in a certain order, to the contemplative life; first, the moral virtues; secondly, other acts exclusive of contemplation; thirdly, contemplation of the divine effects; fourthly, the complement of all which is the contemplation of the divine truth itself.
Reply Obj. 1: David sought the knowledge of God's works, so that he might be led by them to God; wherefore he says elsewhere (Ps. 142:5, 6): "I meditated on all Thy works: I meditated upon the works of Thy hands: I stretched forth my hands to Thee."
Reply Obj. 2: By considering the divine judgments man is guided to the consideration of the divine justice; and by considering the divine benefits and promises, man is led to the knowledge of God's mercy or goodness, as by effects already manifested or yet to be vouchsafed.
Reply Obj. 3: These six denote the steps whereby we ascend by means of creatures to the contemplation of God. For the first step consists in the mere consideration of sensible objects; the second step consists in going forward from sensible to intelligible objects; the third step is to judge of sensible objects according to intelligible things; the fourth is the absolute consideration of the intelligible objects to which one has attained by means of sensibles; the fifth is the contemplation of those intelligible objects that are unattainable by means of sensibles, but which the reason is able to grasp; the sixth step is the consideration of such intelligible things as the reason can neither discover nor grasp, which pertain to the sublime contemplation of divine truth, wherein contemplation is ultimately perfected.
Reply Obj. 4: The ultimate perfection of the human intellect is the divine truth: and other truths perfect the intellect in relation to the divine truth. _______________________
