"Now after John was arrested, Jesus came into Galilee, preaching the gospel of God, and saying: 'The time is fulfilled, and the kingdom of God is at hand: repent, and believe in the gospel.'" 246 "To carry out the will of the Father Christ inaugurated the kingdom of heaven on earth." 247 Now the Father's will is "to raise up men to share in his own divine life". 248 He does this by gathering men around his Son Jesus Christ. This gathering is the Church, "on earth the seed and beginning of that kingdoms". 249

In the New Testament, the word basileia can be translated by "kingship" (abstract noun), "kingdom" (concrete noun) or "reign" (action noun). the Kingdom of God lies ahead of us. It is brought near in the Word incarnate, it is proclaimed throughout the whole Gospel, and it has come in Christ's death and Resurrection. the Kingdom of God has been coming since the Last Supper and, in the Eucharist, it is in our midst. the kingdom will come in glory when Christ hands it over to his Father:

It was the Son's task to accomplish the Father's plan of salvation in the fullness of time. Its accomplishment was the reason for his being sent. 160 "The Lord Jesus inaugurated his Church by preaching the Good News, that is, the coming of the Reign of God, promised over the ages in the scriptures." 161 To fulfill the Father's will, Christ ushered in the Kingdom of heaven on earth. the Church "is the Reign of Christ already present in mystery." 162

The Law, the sign of God's promise and covenant, ought to have governed the hearts and institutions of that people to whom Abraham's faith gave birth. "If you will obey my voice and keep my covenant, . . . you shall be to me a kingdom of priests and a holy nation." 75 But after David, Israel gave in to the temptation of becoming a kingdom like other nations. the Kingdom, however, the object of the promise made to David, 76 would be the work of the Holy Spirit; it would belong to the poor according to the Spirit.

From the day Peter confessed that Jesus is the Christ, the Son of the living God, the Master "began to show his disciples that he must go to Jerusalem and suffer many things. . . and be killed, and on the third day be raised." 290 Peter scorns this prediction, nor do the others understand it any better than he. 291 In this context the mysterious episode of Jesus' Transfiguration takes place on a high mountain, 292 before three witnesses chosen by himself: Peter, James and John. Jesus' face and clothes become dazzling with light, and Moses and Elijah appear, speaking "of his departure, which he was to accomplish at Jerusalem". 293 A cloud covers him and a voice from heaven says: "This is my Son, my Chosen; listen to him!" 294

Jesus entrusted a specific authority to Peter: "I will give you the keys of the kingdom of heaven, and whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven." 287 The "power of the keys" designates authority to govern the house of God, which is the Church. Jesus, the Good Shepherd, confirmed this mandate after his Resurrection: "Feed my sheep." 288 The power to "bind and loose" connotes the authority to absolve sins, to pronounce doctrinal judgements, and to make disciplinary decisions in the Church. Jesus entrusted this authority to the Church through the ministry of the apostles 289 and in particular through the ministry of Peter, the only one to whom he specifically entrusted the keys of the kingdom.

Simon Peter holds the first place in the college of the Twelve; 283 Jesus entrusted a unique mission to him. Through a revelation from the Father, Peter had confessed: "You are the Christ, the Son of the living God." Our Lord then declared to him: "You are Peter, and on this rock I will build my Church, and the gates of Hades will not prevail against it." 284 Christ, the "living Stone", 285 thus assures his Church, built on Peter, of victory over the powers of death. Because of the faith he confessed Peter will remain the unshakeable rock of the Church. His mission will be to keep this faith from every lapse and to strengthen his brothers in it. 286

From the beginning of his public life Jesus chose certain men, twelve in number, to be with him and to participate in his mission. 280 He gives the Twelve a share in his authority and 'sent them out to preach the kingdom of God and to heal." 281 They remain associated for ever with Christ's kingdom, for through them he directs the Church:

The coming of God's kingdom means the defeat of Satan's: "If it is by the Spirit of God that I cast out demons, then the kingdom of God has come upon you." 277 Jesus' exorcisms free some individuals from the domination of demons. They anticipate Jesus' great victory over "the ruler of this world". 278 The kingdom of God will be definitively established through Christ's cross: "God reigned from the wood." 279

By freeing some individuals from the earthly evils of hunger, injustice, illness and death, 274 Jesus performed messianic signs. Nevertheless he did not come to abolish all evils here below, 275 but to free men from the gravest slavery, sin, which thwarts them in their vocation as God's sons and causes all forms of human bondage. 276

The signs worked by Jesus attest that the Father has sent him. They invite belief in him. 269 To those who turn to him in faith, he grants what they ask. 270 So miracles strengthen faith in the One who does his Father's works; they bear witness that he is the Son of God. 271 But his miracles can also be occasions for "offence"; 272 they are not intended to satisfy people's curiosity or desire for magic Despite his evident miracles some people reject Jesus; he is even accused of acting by the power of demons. 273

Jesus accompanies his words with many "mighty works and wonders and signs", which manifest that the kingdom is present in him and attest that he was the promised Messiah. 268

Jesus' invitation to enter his kingdom comes in the form of parables, a characteristic feature of his teaching. 261 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. 262 Words are not enough, deeds are required. 263 The parables are like mirrors for man: will he be hard soil or good earth for the word? 264 What use has he made of the talents he has received? 265 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". 266 For those who stay "outside", everything remains enigmatic. 267

Jesus invites sinners to the table of the kingdom: "I came not to call the righteous, but sinners." 258 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". 259 The supreme proof of his love will be the sacrifice of his own life "for the forgiveness of sins". 260

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"; 253 he declares them blessed, for "theirs is the kingdom of heaven." 254 To them - the "little ones" the Father is pleased to reveal what remains hidden from the wise and the learned. 255 Jesus shares the life of the poor, from the cradle to the cross; he experiences hunger, thirst and privation. 256 Jesus identifies himself with the poor of every kind and makes active love toward them the condition for entering his kingdom. 257

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. 251 To enter it, one must first accept Jesus' word:

Christ stands at the heart of this gathering of men into the "family of God". By his word, through signs that manifest the reign of God, and by sending out his disciples, Jesus calls all people to come together around him. But above all in the great Paschal mystery - his death on the cross and his Resurrection - he would accomplish the coming of his kingdom. "and I, when I am lifted up from the earth, will draw all men to myself." Into this union with Christ all men are called. 250

"The kingdom of God (is) righteousness and peace and joy in the Holy Spirit." 90 The end-time in which we live is the age of the outpouring of the Spirit. Ever since Pentecost, a decisive battle has been joined between "the flesh" and the Spirit. 91
