Reply Obj. 3: As the Apostle says (Heb. 4:15), Christ wished to be "tempted in all things, without sin." Now temptation which comes from an enemy can be without sin: because it comes about by merely outward suggestion. But temptation which comes from the flesh cannot be without sin, because such a temptation is caused by pleasure and concupiscence; and, as Augustine says (De Civ. Dei xix), "it is not without sin that 'the flesh desireth against the spirit.'" And hence Christ wished to be tempted by an enemy, but not by the flesh. _______________________
SECOND ARTICLE [III, Q. 41, Art. 2]
Whether Christ Should Have Been Tempted in the Desert?
Objection 1: It would seem that Christ should not have been tempted in the desert. Because Christ wished to be tempted in order to give us an example, as stated above (A. 1). But an example should be set openly before those who are to follow it. Therefore He should not have been tempted in the desert.
Obj. 2: Further, Chrysostom says (Hom. xii in Matth.): "Then most especially does the devil assail by tempting us, when he sees us alone. Thus did he tempt the woman in the beginning when he found her apart from her husband." Hence it seems that, by going into the desert to be tempted, He exposed Himself to temptation. Since, therefore, His temptation is an example to us, it seems that others too should take such steps as will lead them into temptation. And yet this seems a dangerous thing to do, since rather should we avoid the occasion of being tempted.
Obj. 3: Further, Matt. 4:5, Christ's second temptation is set down, in which "the devil took" Christ up "into the Holy City, and set Him upon the pinnacle of the Temple": which is certainly not in the desert. Therefore He was not tempted in the desert only.
On the contrary, It is written (Mk. 1:13) that Jesus "was in the desert forty days and forty nights, and was tempted by Satan."
I answer that, As stated above (A. 1, ad 2), Christ of His own free-will exposed Himself to be tempted by the devil, just as by His own free-will He submitted to be killed by his members; else the devil would not have dared to approach Him. Now the devil prefers to assail a man who is alone, for, as it is written (Eccles. 4:12), "if a man prevail against one, two shall withstand him." And so it was that Christ went out into the desert, as to a field of battle, to be tempted there by the devil. Hence Ambrose says on Luke 4:1, that "Christ was led into the desert for the purpose of provoking the devil. For had he," i.e. the devil, "not fought, He," i.e. Christ, "would not have conquered." He adds other reasons, saying that "Christ in doing this set forth the mystery of Adam's delivery from exile," who had been expelled from paradise into the desert, and "set an example to us, by showing that the devil envies those who strive for better things."
Reply Obj. 1: Christ is set as an example to all through faith, according to Heb. 12:2: "Looking on Jesus, the author and finisher of faith." Now faith, as it is written (Rom. 10:17), "cometh by hearing," but not by seeing: nay, it is even said (John 20:29): "Blessed are they that have not seen and have believed." And therefore, in order that Christ's temptation might be an example to us, it behooved that men should not see it, and it was enough that they should hear it related.
Reply Obj. 2: The occasions of temptation are twofold. One is on the part of man—for instance, when a man causes himself to be near to sin by not avoiding the occasion of sinning. And such occasions of temptation should be avoided, as it is written of Lot (Gen. 19:17): "Neither stay thou in all the country about" Sodom.
