Furthermore, by His rising on the third day, the perfection of the number "three" is commended, which is "the number of everything," as having "beginning, middle, and end," as is said in De Coelo i. Again in the mystical sense we are taught that Christ by "His one death" (i.e. of the body) which was light, by reason of His righteousness, "destroyed our two deaths" (i.e. of soul and body), which are as darkness on account of sin; consequently, He remained in death for one day and two nights, as Augustine observes (De Trin. iv).
And thereby is also signified that a third epoch began with the Resurrection: for the first was before the Law; the second under the Law; and the third under grace. Moreover the third state of the saints began with the Resurrection of Christ: for, the first was under figures of the Law; the second under the truth of faith; while the third will be in the eternity of glory, which Christ inaugurated by rising again.
Reply Obj. 1: The head and members are likened in nature, but not in power; because the power of the head is more excellent than that of the members. Accordingly, to show forth the excellence of Christ's power, it was fitting that He should rise on the third day, while the resurrection of the rest is put off until the end of the world.
Reply Obj. 2: Detention implies a certain compulsion. But Christ was not held fast by any necessity of death, but was "free among the dead": and therefore He abode a while in death, not as one held fast, but of His own will, just so long as He deemed necessary for the instruction of our faith. And a task is said to be done "at once" which is performed within a short space of time.
Reply Obj. 3: As stated above (Q. 51, A. 4, ad 1, 2), Christ rose early when the day was beginning to dawn, to denote that by His Resurrection He brought us to the light of glory; just as He died when the day was drawing to its close, and nearing to darkness, in order to signify that by His death He would destroy the darkness of sin and its punishment. Nevertheless He is said to have risen on the third day, taking day as a natural day which contains twenty-four hours. And as Augustine says (De Trin. iv): "The night until the dawn, when the Lord's Resurrection was proclaimed, belongs to the third day. Because God, who made the light to shine forth from darkness, in order that by the grace of the New Testament and partaking of Christ's rising we might hear this—'once ye were darkness, but now light in the Lord'—insinuates in a measure to us that day draws its origin from night: for, as the first days are computed from light to darkness on account of man's coming fall, so these days are reckoned from darkness to light owing to man's restoration." And so it is evident that even if He had risen at midnight, He could be said to have risen on the third day, taking it as a natural day. But now that He rose early, it can be affirmed that He rose on the third day, even taking the artificial day which is caused by the sun's presence, because the sun had already begun to brighten the sky. Hence it is written (Mk. 16:2) that "the women come to the sepulchre, the sun being now risen"; which is not contrary to John's statement "when it was yet dark," as Augustine says (De Cons. Evang. iii), "because, as the day advances the more the light rises, the more are the remaining shadows dispelled." But when Mark says "'the sun being now risen,' it is not to be taken as if the sun were already apparent over the horizon, but as coming presently into those parts." _______________________
THIRD ARTICLE [III, Q. 53, Art. 3]
Whether Christ Was the First to Rise from the Dead?
Objection 1: It would seem that Christ was not the first to rise from the dead, because we read in the Old Testament of some persons raised to life by Elias and Eliseus, according to Heb. 11:35: "Women received their dead raised to life again": also Christ before His Passion raised three dead persons to life. Therefore Christ was not the first to rise from the dead.
Obj. 2: Further, among the other miracles which happened during the
Passion, it is narrated (Matt. 27:52) that "the monuments were
opened, and many bodies of the saints who had slept rose again."
Therefore Christ was not the first to rise from the dead.
Obj. 3: Further, as Christ by His own rising is the cause of our resurrection, so by His grace He is the cause of our grace, according to John 1:16: "Of His fulness we all have received." But in point of time some others had grace previous to Christ—for instance all the fathers of the Old Testament. Therefore some others came to the resurrection of the body before Christ.
