Now the Evangelist Mark says: “It was the third hour, and they crucified Him” (Mk 15:25). What does this mean, except that the Lord was crucified at the third hour by the tongues of the Jews, and at the sixth hour by the hands of the soldiers?
Thus we may understand that the fifth hour had already passed and some beginning of the sixth had come when Pilate sat on the judgment seat. John expresses this with the words “about the sixth hour.” When He was led away, nailed to the tree with the two robbers, and the things related in the Gospel happened at the cross, the sixth hour was fully completed.
From that hour until the ninth the sun was darkened and darkness came. This is attested by the three Evangelists: Matthew, Mark, and Luke (Mt 27:45; Mk 15:33; Lk 23:44).
But because the Jews sought to shift the murder of Christ from themselves onto the Romans, that is, onto Pilate and his soldiers, Mark passed over the hour when Christ was crucified by the soldiers. This was already happening from the sixth hour. He mentioned only the third hour, when they may be understood to have cried before Pilate: “Crucify Him, crucify Him!” (Jn 19:6).
Thus it would be clear that Christ was crucified not only by those who hung Him on the tree at the sixth hour, that is, the soldiers, but also by the Jews, who at the third hour cried that He should be crucified.
There is also another solution to this question. Here one should not understand the sixth hour of the day. John does not say, “It was about the sixth hour of the day,” or simply, “about the sixth hour.” Rather, he says: “Now it was the parasceve of the Passover, about the sixth hour.”
Parasceve in Latin is praeparatio, preparation. It is a Greek word, and the Jews readily use it in such cases, even those who speak Latin more than Greek. Thus it was the preparation of the Passover. Our Passover, as the Apostle says, is Christ slain (cf. 1 Cor 5:7).
If we count the preparation of this Passover from the ninth hour of the night, then the matter is clear. For then the chief priests seem to have passed sentence on the Lord, saying: “He is liable to death” (Mt 26:66), while He was still being heard in the high priest’s house.
It is fitting to suppose that the preparation of the true Passover, of which the Jewish Passover was a shadow, began from that moment. This was the preparation for the slaying of Christ, when the chief priests passed sentence that He must be slain.
From that hour of the night, which is supposed to have been the ninth hour, until the third hour of the day, when Christ was crucified according to the testimony of the Evangelist Mark, six hours passed: three by night and three by day.
In antiquity the hours of a full day were counted separately: twelve by day and twelve by night. Therefore the ninth hour of the night is the ninth hour from sunset, and the third hour of the day is the third hour from sunrise. Thus the Sanhedrin passed its sentence three hours before dawn, and the execution took place three hours after dawn.
Accordingly this preparation of the Passover, that is, the preparation for the slaying of Christ, which began at the ninth hour of the night, lasted about six hours. The fifth hour had been completed, and the sixth was beginning when Pilate ascended the judgment seat.
This very preparation, which began at the ninth hour of the night, lasted until the slaying of Christ took place, for which the preparation was being made. This occurred, according to Mark, at the third hour, but not the third hour of the preparation. It was the third hour of the day.
Likewise the sixth hour was not the sixth hour of the day, but of the preparation, if, of course, one counts six hours from the ninth hour of the night to the third hour of the day.
Of these two solutions to this difficult question, let each choose the one he wishes. But the one who reads the serious discussions On the Harmony of the Evangelists will decide with greater reason which is better to choose. If other solutions can be found, let the unshakable truth of the Gospel be defended still better against the slander of unbelieving and impious vanity.
Now, after this brief discussion, let us return to the narrative of the Evangelist John.
