Here is
Cardinal Lapide’s commentary on the matter - at the end he references some ancient habits to speak in this way:*You will ask, how Christ was three days and nights in the sepulchre and Limbus: for He was there only on Friday and Saturday nights, and rose at day-break on Sunday? 1. Alcuin (L. de. Divinis 0ff. sec. de. Cœna. Dom.) gathers from this place that Christ lay in the tomb three whole days and nights, or 72 hours, and consequently rose again at the end of Easter Monday. But this is certainly a mistake. The constant tradition of the church is that Christ rose on the Lord’s day.
- Greg. Nyssen (Orat. 1 &. 2 de Resurrec.) computes these three days to begin on Thursday. He is of opinion, that when on the evening of that day Christ instituted the Eucharist, He offered Himself to God under the species of bread and wine by means of the unbloody sacrifice. The soul of Christ was separated from the body, but that this was done in a secret and invisible manner, and that then the soul of Christ went down to Hades, and that thus He pre-accomplished His death, which the Jews were visibly to bring about on the following day upon the cross. But this, too, is an error. For there is really in the Eucharist the soul of the Living Christ, that is to say, in His body and blood contained under the species of bread and wine. It is there, I say, not indeed by virtue of the words of consecration, but by natural concomitance. For in the Eucharist there is Living Christ, with His Soul, even as He is outside the Eucharist. Thus the Council of Trent defines (Sess. 13, sec. 2). It would have been otherwise if any of the Apostles had consecrated the Eucharist during the triduum of the Passion. For then the Body and Blood of Christ would have been in it separated from His Soul, for in this manner they were in Christ Himself now buried. For Christ was then dead, not alive.
I say then, that the expression three days and three nights is here only a periphrasis and description of a natural day. The two integral parts of such a day are day and night, or light and darkness. Christ makes use of this periphrasis because Jonah, His antetype, did the same. (Jonah i. 17.) We must not understand that these days are three artificial days as opposed to nights, as if during three days, in which the sun is above the horizon, Christ lay in the tomb; for this was not the case. You must consider these three natural days to be not whole days but parts of days, namely, the latter part of Friday; when Christ being taken down from the Cross, was laid in the sepulchre, the whole of Saturday, and part of the Lord’s day. For although the Hebrews reckoned their civil days from one sun-rise to another, like the Chaldeans and the Persians (Beda de ration. temp.), yet they computed their sacred days, such as the Passover, from evening to evening. Thus S. Jerome, Theophyl., Euthym., and S. Aug. and commentators, passim, explain the meaning of these three days. Hence Christ is constantly spoken of as rising on the third day, or after three days, without any mention of nights.
But in this place, according to this computation, there were but two nights in which Christ lay in the tomb, viz. Friday and Saturday nights, and yet three nights are expressly mentioned. Others therefore answer more fully and plainly; that these three days and nights are reckoned according to the Roman computation. For the Romans were at that time, masters of Judea, and had introduced their own methods of computing time in civil affairs. The Romans reckoned from midnight to midnight, as Christians do in their fasts and festivals. (See Macrob. L. 1. Saturni c. Gell. L. 3. c. 2. Pliny. L. 2. c. 77. and others). According to this reckoning it is clear Christ remained in the tomb during a part of three days and three nights. He was buried on Friday before sunset; and was in the tomb until the midnight of that day. After that He was in the tomb during the entire day and night of the Sabbath; and from the midnight of Sunday for about six hours until that dawning of the Lord’s Day on which He arose. For the Passover was at that time about the equinox, when the days and nights are equal, each being about twelve hours long. But the Soul of Christ, immediately when He expired upon the Cross at the ninth hour, i.e., at three o’clock in the afternoon, descended into Limbus, and there remained with the Fathers until the dawn of Easter Day. Now that the Jews made use of the Roman method of computing time may be learnt as well from other things, as because they borrowed the four watches of the night from the practice in use among the Roman armies. (See Matt. xiv. 25 and elsewhere.) Different nations had different methods of reckoning the beginning of the day. The Persians and Babylonians reckoned from sunrise to sunrise. The Athenians and Italians, from sunset to sunset. Astronomers from midday to midday. But the Egyptians and Roman priests reckoned from midnight to midnight: and this method has continued in the Roman Church. The Hebrews then in the time of Christ followed the method of the Romans, to whom they were subject. Franc. Lucas teaches that the Jews did not compute their Festivals from midnight as Christians do. The explanation given above is that of S. Anselm, in Loco. Isidore of Pelusium (L. 1. Epist 114 and 212), D. Thom., (3. p. q. 46. art. 9), Suarez (3. p. q. 53. disp. 46. sect. 3. in fine.), and Baronius. (A. C. 34.).*
