Exegesis of "I have come to bring fire..." (Luke 12, 50)

The below offers an exegesis of the Gospel of today (20th Sunday in Ordinary Time C): LK 12:49-53 Jesus said to his disciples: “I have come to set the earth on fire, and how I wish it were already blazing! There is a baptism with which I must be baptized, and how great is my anguish until it is accomplished! Do you think that I have come to establish peace on the earth? No, I tell you, but rather division. From now on a household of five will be divided, three against two and two against three; a father will be divided against his son and a son against his father, a mother against her daughter and a daughter against her mother, a mother-in-law against her daughter-in-law and a daughter-in-law against her mother-in-law.” Commentary of St. John Chrysostom [2nd Reading of the Office of Readings]. "You are the salt of the earth. It is not for your own sake, he says, but for the world’s sake that the word is entrusted to you. I am not sending you only into two cities only or ten to twenty, not to a single nation, as I sent the prophets of old, but across land and sea, to the whole world. And that world is in a miserable state. For when he says: You are the salt of the earth, he is indicating that all mankind had lost its savor and had been corrupted by sin. Therefore, he requires of these men those virtues which are especially useful and even necessary if they are to bear the burdens of many. For the man who is kindly, modest, merciful and just will not keep his good works to himself but will see to it that these admirable fountains send out their streams for the good of others. Again, the man who is clean of heart, a peacemaker and ardent for truth will order his life so as to contribute to the common good. "Do not think, he says, that you are destined for easy struggles or unimportant tasks. You are the salt of the earth. What do these words imply? Did the disciples restore what had already turned rotten? Not at all. Salt cannot help what is already corrupted. That is not what they did. But what had first been renewed and freed from corruption and then turned over to them, they salted and preserved in the newness the Lord had bestowed. It took the power of Christ to free men from the corruption caused by sin; it was the task of the apostles through strenuous labor to keep that corruption from returning. "Have you noticed how, bit by bit, Christ shows them to be superior to the prophets? He says they are to be teachers not simply for Palestine but for the whole world. Do not be surprised, then, he says, that I address you apart from the others and involve you in such a dangerous enterprise. Consider the numerous and extensive cities, peoples and nations I will be sending you to govern. For this reason I would have you make others prudent, as well as being prudent yourselves. For unless you can do that, you will not be able to sustain even yourselves. "If others lose their savor, then your ministry will help them regain it. But if you yourselves suffer that loss, you will drag others down with you. Therefore, the greater the undertakings put into your hands, the more zealous you must be. For this reason he says: But if the salt becomes tasteless, how can its flavor be restored? It is good for nothing now, but to be thrown out and trampled by men’s feet. "When they hear the words: When they curse you and persecute you and accuse you of every evil, They may be afraid to come forward. Therefore he says: “Unless you are prepared for that sort of thing, it is in vain that I have chosen you. Curses shall necessarily be your lot but they shall not harm you and will simply be a testimony to your constancy. If through fear, however, you fail to show the forcefulness your mission demands, your lot will be much worse, for all will speak evil of you and despise you. That is what being trampled by men’s feet means”. "Then he passes on to a more exalted comparison: You are the light of the world. Once again, “of the world”: not of one nation or twenty cities, but of the whole world. The light he means is an intelligible light, far superior to the rays of the sun we see, just as the salt is a spiritual salt. First salt, then light, so that you may learn how profitable sharp words may be and how useful serious doctrine. Such teaching holds in check and prevents dissipation; it leads to virtue and sharpens the mind’s eye. A city set on a hill cannot be hidden; nor do men light a lamp and put it under a basket. Here again he is urging them to a careful manner of life and teaching them to be watchful, for they live under the eyes of all and have the whole world for the arena of their struggles." [ This excerpt from a homily by Saint John Chrysostom on the Gospel of St. Matthew (Hom 15, 6-7: PG 57, 231-232) comments on the famous lines in the Sermon on the Mount in which Jesus calls his disciples the Salt of the Earth and the Light of the World (Matt. 5: 15-16).  This appears in the Roman Office of Readings on the 20th Sunday in ordinary time with the corresponding biblical reading taken from Isaiah 6: 1-13]. Blogger adds: The vocation embedded in the Sacrament of Baptism is to become another Christ. St. Josemaria Escriva insisted that the vocation empowered by Baptism is not for an elite few who feel an attraction to the "consecrated life" of leaving the world and taking vows, but for all the baptized. Escriva wrote: "In the spiritual life, there is no new era to come. Every thing is already there, in Christ who died and rose again, who  lives and stays with us always. But we have to join him through faith, letting his life show forth in ours to such an extent that each Christian is not simply alter Christus: another Christ, but ipse Christus: Christ himself!" [Christ is Passing By #104]    This is the same thought as Joseph Ratzinger's understanding of eschatology - correctly - i.e., our not being mired in a hiatus between the Ascension of Our Lord into heaven 2000 years ago and the Second Coming. His eschatology reads Christ as present now, but recognized only by those who have gone through an interior conversion as self-gift (faith in act as prayer). That lacking, the presence of Christ (and the ongoing miracles of faith that are constantly taking place) are not re-cognized. Christ must be experienced ab intus (intellegere = legere ab intus (read from within) by the self-transcendence of faith, and thus "cognized." Christ is present now - in the world - by individual Christians becoming Christ (the "already" in Baptism that is the "not yet" of the achieved actuality of total self-gift unto martyrdom) which is the fulfillment of Jn 12, 32 that Escriva heard during that Mass of August 7, 1931: "And I, when I am lifted up from the earth, will draw all things to myself." Years later Escriva commented that he understood Christ saying those words "not in the sense in which in which Scripture says them. I say it to you in the sense that you are to raise me  up in all human activities, in the sense that all over the world there should be Christians with a personal and most free dedication, that they be other Christs" (Coverdale, "Uncommon Faith" Scepter [2002] 90).   That is "the Fire!" And Pope Francis is calling all of us to the exodus from self that makes it burn.
