Luke 12:50

But our Lord was hastening the kindling of the fire, and hence it follows, And what will I, save that it be kindled? (nisi ut accendatur) For already some of the Jews believed, of whom the first were the holy Apostles, but the fire once lighted in Judaea was about to take possession of the whole world, yet not till after the dispensation of His Passion had been accomplished. Hence it follows, But I have a baptism to be baptized with. For before the holy cross and His resurrection from the dead, in Judaea only was the news told of His preaching and miracles; but after that the Jews in their rage had slain the Prince of life, then commanded He His Apostles, saying, Go and teach all nations. (Matt. 28:19.)

But He adds, I have a baptism to be baptized with, that is, I have first to be sprinkled with the drops of My own Blood, and then to inflame the hearts of believers by the fire of the Spirit.

Some manuscripts have, "And how am I anguished," (coangor) that is, grieved. For though He had in Himself nothing to grieve Him, yet was He afflicted by our woes, and at the time of death He betrayed the anguish which He underwent not from the fear of His death, but from the delay of our redemption. For he who is troubled until he reaches perfection, is secure of perfection, for the condition of bodily affections not the dread of death offends him. For ho who has put on the body must suffer all things which are of the body, hunger, thirst, vexation, sorrow; but the Divine nature knows no change from such feelings. At the same time He also shows, that in the conflict of suffering consists the death of the body, peace of mind has no struggle with grief.

To stewards, that is, to Priests, the preceding words seem to have been addressed, that they may thereby know that hereafter a heavier punishment awaits them, if, intent upon the world's pleasures, they have neglected the charge of their Lord's household, and the people entrusted to their care. But as it profiteth little to be recalled from error by the fear of punishment, and far greater is the privilege of charity and love, our Lord therefore kindles in men the desire of acquiring the divine nature, saying, I came to send fire on earth, not indeed that He is the Consumer of good men, but the Author of good will, who purifies the golden vessels of the Lord's house, but burns up the straw and stubble. But so great was our Lord's condescension, that He tells us He has a desire of inspiring us with devotion, of accomplishing perfection in us, and of hastening His passion for us; as it follows, And how am I straitened till it be accomplished?
