A reading from the Book of Genesis
18:16-33
Abraham and the men who had visited him by the Terebinth of Mamre
set out from there and looked down toward Sodom;
Abraham was walking with them, to see them on their way.
The LORD reflected: "Shall I hide from Abraham what I am about to do,
now that he is to become a great and populous nation,
and all the nations of the earth are to find blessing in him?
Indeed, I have singled him out
that he may direct his children and his household after him
to keep the way of the LORD
by doing what is right and just,
so that the LORD may carry into effect for Abraham
the promises he made about him."
Then the LORD said:
"The outcry against Sodom and Gomorrah is so great,
and their sin so grave,
that I must go down and see whether or not their actions
fully correspond to the cry against them that comes to me.
I mean to find out."
While the two men walked on farther toward Sodom,
the LORD remained standing before Abraham.
Then Abraham drew nearer to him and said:
"Will you sweep away the innocent with the guilty?
Suppose there were fifty innocent people in the city;
would you wipe out the place, rather than spare it
for the sake of the fifty innocent people within it?
Far be it from you to do such a thing,
to make the innocent die with the guilty,
so that the innocent and the guilty would be treated alike!
Should not the judge of all the world act with justice?"
The LORD replied,
"If I find fifty innocent people in the city of Sodom,
I will spare the whole place for their sake."
Abraham spoke up again:
"See how I am presuming to speak to my Lord,
though I am but dust and ashes!
What if there are five less than fifty innocent people?
Will you destroy the whole city because of those five?"
He answered, "I will not destroy it if I find forty-five there."
But Abraham persisted, saying, "What if only forty are found there?"
He replied, "I will forbear doing it for the sake of forty."
Then Abraham said, "Let not my Lord grow impatient if I go on.
What if only thirty are found there?"
He replied, "I will forbear doing it if I can find but thirty there."
Still Abraham went on,
"Since I have thus dared to speak to my Lord,
what if there are no more than twenty?"
He answered, "I will not destroy it for the sake of the twenty."
But he still persisted:
"Please, let not my Lord grow angry if I speak up this last time.
What if there are at least ten there?"
He replied, "For the sake of those ten, I will not destroy it."
The LORD departed as soon as he had finished speaking with Abraham,
and Abraham returned home.
From the Gospel according to Matthew
8:18-22
When Jesus saw a crowd around him,
he gave orders to cross to the other shore.
A scribe approached and said to him,
“Teacher, I will follow you wherever you go.”
Jesus answered him, “Foxes have dens and birds of the sky have nests,
but the Son of Man has nowhere to rest his head.”
Another of his disciples said to him,
“Lord, let me go first and bury my father.”
But Jesus answered him, “Follow me,
and let the dead bury their dead.”
The Evangelist Luke presents to us Jesus, walking to Jerusalem, who meets some men on the road probably young men who promise they will follow him wherever he goes. Jesus proves very demanding with them and warns them that "the Son of Man", namely, the Messiah, "has nowhere to lay his head" that is to say, he has no permanent dwelling place of his own and that those who choose to work with him in God's field cannot turn back (cf. Lk 9:57-58; 61-62). On the other hand Christ says to someone else: "Follow me", asking him to sever completely his ties with his family (cf. Lk 9:59-60). These requirements may seem too harsh but in fact they express the newness and absolute priority of the Kingdom of God that is made present in the very Person of Jesus Christ. All things considered, it is a question of that radicalism that is due to the Love of God, whom Jesus himself was the first to obey. Those who give up everything, even themselves, to follow Jesus, enter into a new dimension of freedom that St Paul defines as "walk[ing] by the Spirit" (cf. Gal 5:16). "For freedom Christ has set us free", the Apostle writes, and he explains that this new form of freedom acquired from Christ consists in being "servants of one another" (Gal 5:1, 13). Freedom and love coincide! On the contrary, complying with one's own egoism leads to rivalry and conflict. (Pope Benedict XVI, Angelus, 27 June 2010)
