Hilary of Poitiers

Is the cause of this sadness and this prayer any longer doubtful? He bids them to watch and pray with him for this purpose, that they may not enter into temptation; “for the spirit indeed is willing, but the flesh is weak.” If they had remained firm under the promise to faithful souls, they would not have violated their trust. Yet through the weakness of the flesh, they did fall away. It is not, therefore, for himself that the Lord is sorrowing and prays. It is for those whom he exhorts to watchfulness and prayer, lest the cup of suffering should be their lot, lest that cup which he prays may pass away from him should rest with them.

If you will not learn who Christ is from those who received him, at least learn from those who rejected him. The ironic confession his adversaries were inadvertently forced to make stands as reproof of their very mockery. His accusers did not recognize Christ when he came bodily. Yet they had grasped firmly that the true Christ must be the Son of God. Thus, when the false witnesses whom they had hired against him did not score any blows, the priest interrogated him: “Are you the Christ, the Son of the most high God.” They did not realize that the mystery was already being fulfilled in him. But they did, ironically, recognize that the divine nature was the condition of its fulfillment. They did not question the assumption that Christ would be the Son of God. They only asked whether he indeed was the Christ, the Son of God. They were mistaken about the person, but not about the Son of God. They had no doubt that Christ would be the Son of God. So while they asked whether he indeed was the Christ, they did so without denying that the Christ is the Son of God.
