Jesus began to speak to the chief priests and elders of the people in parables: ‘The kingdom of heaven may be compared to a king who gave a feast for his son’s wedding. He sent his servants to call those who had been invited, but they would not come. Next he sent some more servants. “Tell those who have been invited” he said “that I have my banquet all prepared, my oxen and fattened cattle have been slaughtered, everything is ready. Come to the wedding.” But they were not interested: one went off to his farm, another to his business, and the rest seized his servants, maltreated them and killed them. The king was furious. He despatched his troops, destroyed those murderers and burnt their town. Then he said to his servants, “The wedding is ready; but as those who were invited proved to be unworthy, go to the crossroads in the town and invite everyone you can find to the wedding.” So these servants went out on to the roads and collected together everyone they could find, bad and good alike; and the wedding hall was filled with guests. When the king came in to look at the guests he noticed one man who was not wearing a wedding garment, and said to him, “How did you get in here, my friend, without a wedding garment?” And the man was silent. Then the king said to the attendants, “Bind him hand and foot and throw him out into the dark, where there will be weeping and grinding of teeth.” For many are called, but few are chosen.’

The proclamation of the kingdom of God
543 Everyone is called to enter the kingdom. First announced to the children of Israel, this messianic kingdom is intended to accept men of all nations. To enter it, one must first accept Jesus’ word:
The word of the Lord is compared to a seed which is sown in a field; those who hear it with faith and are numbered among the little flock of Christ have truly received the kingdom. Then, by its own power, the seed sprouts and grows until the harvest.
544 The kingdom belongs to the poor and lowly, which means those who have accepted it with humble hearts. Jesus is sent to “preach good news to the poor”; he declares them blessed, for “theirs is the kingdom of heaven.” To them – the “little ones” the Father is pleased to reveal what remains hidden from the wise and the learned. Jesus shares the life of the poor, from the cradle to the cross; he experiences hunger, thirst and privation. Jesus identifies himself with the poor of every kind and makes active love toward them the condition for entering his kingdom.
545 Jesus invites sinners to the table of the kingdom: “I came not to call the righteous, but sinners.” He invites them to that conversion without which one cannot enter the kingdom, but shows them in word and deed his Father’s boundless mercy for them and the vast “joy in heaven over one sinner who repents”. The supreme proof of his love will be the sacrifice of his own life “for the forgiveness of sins”.
546 Jesus’ invitation to enter his kingdom comes in the form of parables, a characteristic feature of his teaching. Through his parables he invites people to the feast of the kingdom, but he also asks for a radical choice: to gain the kingdom, one must give everything. Words are not enough, deeds are required. The parables are like mirrors for man: will he be hard soil or good earth for the word? What use has he made of the talents he has received? Jesus and the presence of the kingdom in this world are secretly at the heart of the parables. One must enter the kingdom, that is, become a disciple of Christ, in order to “know the secrets of the kingdom of heaven”. For those who stay “outside”, everything remains enigmatic.
For the leader; according to “The deer of the dawn.” A psalm of David.
My God, my God, why have you abandoned me? Why so far from my call for help, from my cries of anguish?
My God, I call by day, but you do not answer; by night, but I have no relief.
Yet you are enthroned as the Holy One; you are the glory of Israel.
In you our ancestors trusted; they trusted and you rescued them.
To you they cried out and they escaped; in you they trusted and were not disappointed.
But I am a worm, hardly human, scorned by everyone, despised by the people.
All who see me mock me; they curl their lips and jeer; they shake their heads at me:
“You relied on the LORD – let him deliver you; if he loves you, let him rescue you.”
Yet you drew me forth from the womb, made me safe at my mother’s breast.
Upon you I was thrust from the womb; since birth you are my God.
Do not stay far from me, for trouble is near, and there is no one to help.
Many bulls surround me; fierce bulls of Bashan encircle me.
They open their mouths against me, lions that rend and roar.
Like water my life drains away; all my bones grow soft. My heart has become like wax, it melts away within me.
As dry as a potsherd is my throat; my tongue sticks to my palate; you lay me in the dust of death.
Many dogs surround me; a pack of evildoers closes in on me. So wasted are my hands and feet
that I can count all my bones. They stare at me and gloat;
they divide my garments among them; for my clothing they cast lots.
But you, LORD, do not stay far off; my strength, come quickly to help me.
Deliver me from the sword, my forlorn life from the teeth of the dog.
Save me from the lion’s mouth, my poor life from the horns of wild bulls.
Then I will proclaim your name to the assembly; in the community I will praise you:
“You who fear the LORD, give praise! All descendants of Jacob, give honor; show reverence, all descendants of Israel!
For God has not spurned or disdained the misery of this poor wretch, Did not turn away from me, but heard me when I cried out.
I will offer praise in the great assembly; my vows I will fulfill before those who fear him.
The poor will eat their fill; those who seek the LORD will offer praise. May your hearts enjoy life forever!”
All the ends of the earth will worship and turn to the LORD; All the families of nations will bow low before you.
For kingship belongs to the LORD, the ruler over the nations.
All who sleep in the earth will bow low before God; All who have gone down into the dust will kneel in homage.
And I will live for the LORD; my descendants will serve you.
The generation to come will be told of the Lord, that they may proclaim to a people yet unborn the deliverance you have brought.
