Secondly, we may be said to pray according to the sensuality when our prayer lays before God what is in our appetite of sensuality; and in this sense Christ prayed with His sensuality inasmuch as His prayer expressed the desire of His sensuality, as if it were the advocate of the sensuality—and this, that He might teach us three things. First, to show that He had taken a true human nature, with all its natural affections: secondly, to show that a man may wish with his natural desire what God does not wish: thirdly, to show that man should subject his own will to the Divine will. Hence Augustine says in the Enchiridion (Serm. 1 in Ps. 32): "Christ acting as a man, shows the proper will of a man when He says 'Let this chalice pass from Me'; for this was the human will desiring something proper to itself and, so to say, private. But because He wishes man to be righteous and to be directed to God, He adds: 'Nevertheless not as I will but as Thou wilt,' as if to say, 'See thyself in Me, for thou canst desire something proper to thee, even though God wishes something else.'"
Reply Obj. 1: The flesh rejoices in the Living God, not by the act of the flesh mounting to God, but by the outpouring of the heart into the flesh, inasmuch as the sensitive appetite follows the movement of the rational appetite.
Reply Obj. 2: Although the sensuality wished what the reason besought, it did not belong to the sensuality to seek this by praying, but to the reason, as stated above.
Reply Obj. 3: The union in person is according to the personal being, which pertains to every part of the human nature; but the uplifting of prayer is by an act which pertains only to the reason, as stated above. Hence there is no parity. _______________________
THIRD ARTICLE [III, Q. 21, Art. 3]
Whether It Was Fitting That Christ Should Pray for Himself?
Objection 1: It would seem that it was not fitting that Christ should pray for Himself. For Hilary says (De Trin. x): "Although His word of beseeching did not benefit Himself, yet He spoke for the profit of our faith." Hence it seems that Christ prayed not for Himself but for us.
Obj. 2: Further, no one prays save for what He wishes, because, as was said (A. 1), prayer is an unfolding of our will to God that He may fulfil it. Now Christ wished to suffer what He suffered. For Augustine says (Contra Faust. xxvi): "A man, though unwilling, is often angry; though unwilling, is sad; though unwilling, sleeps; though unwilling, hungers and thirsts. But He" (i.e. Christ) "did all these things, because He wished." Therefore it was not fitting that He should pray for Himself.
Obj. 3: Further, Cyprian says (De Orat. Dom.): "The Doctor of Peace and Master of Unity did not wish prayers to be offered individually and privately, lest when we prayed we should pray for ourselves alone." Now Christ did what He taught, according to Acts 1:1: "Jesus began to do and to teach." Therefore Christ never prayed for Himself alone.
On the contrary, our Lord Himself said while praying (John 17:1): "Glorify Thy Son."
