Luke 22:43

And there appeared an angel unto Him from heaven. The angel appeared in a body assumed visibly that he might comfort the eyes and ears of Christ by his appearance and voice. Jansenius thinks that the angel appeared at each of Christ's three prayers, and therefore comforted Him three times, to teach us that God always hears those who pray, and gives them grace and strength unceasingly. F. Lucas, and others, think with more reason, that the angel only appeared once, at the third and last prayer, and comforted Him when He prayed more earnestly, and sweated blood, to show that we ought to persevere in prayer, and that the fruit of such perseverance is the comfort of God, and the vision of angels. For after this consolation from the Father by the angel, the agony of Christ seems to have passed away, and He appears to have prayed no more but to have prepared bravely for death. This angel was Gabriel, says Gabriel Vasquez (I. p. tom. ii . disbut. 244, No. 3), for Gabriel has his name from his fortitude, Gabriel being Geber-el the man of God, or Gebura-el the fortitude of God; for he has the office of comforting the weak, afflicted, and fearful. But he comforted Christ not by strengthening His weakness, but by praising His surpassing fortitude. Lud. de Pont. thinks the same in his "Meditation on the Agony of Christ in the Garden," because Gabriel was the legate and messenger of the œconomy of Christ, as at the Incarnation (Luke i. 26), and of the seventy weeks of Daniel, which foretold the time of the nativity of Christ.

Others, however, as F. Lucas, think that it was Michael, for he is the highest of all angels, and it became him, as such, to perform this office for the supreme God, that is Christ.

Strengthening Him. "The praise and due adoration of Christ," says Titus, "being premised," he comforted Christ by speaking to Him outwardly and setting before Him the will and glory of the Father, and the rich fruit which would ensue, both to Christ Himself, to men, and to angels, from His Passion. For the angel could not affect the inner mind of Christ, nor immediately change His inner powers. And as He could only be tempted by Satan, externally, so He could only be comforted by the angel outwardly. He could not be taught nor illuminated by him, for He was above all angels, and from the first moment of His conception, was full of wisdom and knowledge. So say the schoolmen with S. Thomas (3. p. q. 12 , art. 4): The angel spoke the following, or like words to Christ, "0 Lord, bravest of men, Thy prayer is most acceptable to Thy Father; because, notwithstanding Thy natural dread of death, Thou resignedst Thyself wholly to the will of the Father boldly to undergo the death appointed for Thee by Him. Lay aside therefore this Thy horror and grief with which Thou hast voluntarily invested Thyself, and reassume Thy former mind and strength, and come bravely to the work of human Redemption, by which Thou wilt most signally celebrate the glory of God, rejoice the angels, redeem men from Hell, and bring them back to the glories of heaven. Endure the cross for the joy that is offered Thee, as the future author and perfector of the faith of very many. Hebrews 12:2. Thus Thou wilt cause SS. Peter and Paul, Laurentius, Vincentius, Agnes, Cœcilia and very many other martyrs and virgins, men, and noble heroes and heroines boldly to undergo martyrdom for God, and the faithful, with other holy men, who triumphed gloriously over the flesh, the world, and the devil. I know that Thou, 0 Lord, hast no need of any strengthening of mine, who am myself strengthened by Thee both to be and to live; but, that this my ministry which I execute as a steward at the command of God Thy Father may be acceptable to Thee, I pray again and again."

Theophylact thinks that the angel spoke thus, "0 Lord, Thine is the strength, for thou art powerful against death and hell, to set free the race of men."
