Timeline of the Catholic Church

The History of the Roman Catholic Church covers a period of just under two thousand years, making the Church one of the oldest continuously existing religious institutions in history. As one of the oldest branches of Christianity, the history of the Catholic Church plays an integral part of the History of Christianity as a whole. In simple terms, the term Catholic Church as it is used in this article refers specifically to the Church founded in Jerusalem by Jesus of Nazareth (c. AD 33) and led by an unbroken apostolic succession through St. Peter the Apostle, ruled by the Bishop of Rome as successor of St. Peter, now commonly known as the Pope.

Over time, schisms have disrupted the unity of Christianity. The two largest of these involved the separation from the Catholic Church of Orthodox Christianity the (East-West Schism) and Protestantism (the Reformation) respectively. The Catholic Church has been the moving force in some of the major events of world history including the Evangelization of Europe and Latin America, the spreading of literacy and the foundation of the Universities, hospitals, monasticism, the development of Art, Music and Architecture, the Inquisition, the Crusades, an analytical philosophical method, and the downfall of Communism in Eastern Europe in the late 20th century.

Ministry of Jesus and the Founding of the Church

Jesus as Christ pantocrator

The Catholic Church's institutional basis is the person and teachings of Jesus Christ (b. 6 - 4 BC? Bethlehem, d. AD 33 Jerusalem) as described in the four Gospels of Matthew, Mark, Luke and John. These describe Jesus as an observant Jewish carpenter from the region of Galilee, who was both the promised Messiah or anointed one (Christos in Greek, giving rise to the title Jesus Christ) and son of God, in fulfillment of Old Testament prophecy. Catholicism thus considers itself a successor religion to Judaism with the Christian God and the God of the Jews seen as one and the same.

According to the four Gospels, when Jesus was about thirty years of age (Luke 3:23), he left the town of Nazareth and began a ministry of preaching and miraculous healing. In his preaching, he called for repentance (Mark 1:15), presenting God as a loving Father always ready to forgive. He also called on people to imitate the goodness and love of God towards all. He gained a following of people who saw him as a Rabbi and in some cases wondered if he could be the Messiah; but he aroused opposition from the religious leadership, who saw his teaching as contrary to traditional doctrine and practice, and felt that his hints about his own personal identity were blasphemous.

The Gospels give a detailed account of Jesus' final days, when, probably in his mid-thirties, Jesus was arrested by the Sanhedrin in Jerusalem and charged with blasphemy. To the Sanhedrin he declared himself the Messiah, and they persuaded the authorities of the Roman Empire, who ruled the region as Iudaea Province, to sentence him to death, after which he was scourged, beaten, and crucified. The Passion of Christ, thus recounted in the Gospels, tells of the events of Good Friday (beginning on what would now be considered the evening of the day before), which led up to Easter, when, according to the New Testament account, Jesus rose from the dead and appeared to his disciples. By its own reckoning, the Church began on the first Pentecost when the Holy Spirit descended on the apostles and disciples in the Upper Room.

To Simon Peter, Jesus had earlier stated that he would entrust to him the keys to Heaven and that upon the "rock" (Latin Petrus, Greek Petros, and Aramaic Cepha actually meaning "Stone") of Peter he would found his Church. The Catholic Church believes the Pope as the successor of Saint Peter and the singular leader of the whole Church on earth. The controversy between Rome and the other apostolic churches over what has been called the Petrine Doctrine is one of several doctrinal controversies that continues to divide the eastern and western churches.

Roman Empire (c. 1 — 312)

• c. 1: Nativity of Jesus. According to the Gospels, his birth occurred in the town of Bethlehem during the reigns of King Herod the Great of Judaea and the Roman Emperor Augustus, and he was the son of the Virgin Mary, who conceived him by the power of the Holy Spirit. Christians see Him as as the Divine Son of God incarnate.

Although the calculations of Dionysius Exiguus put the birth of Jesus in the year that in consequence is called AD 1, history places his birth more likely some time between 6 and 4 BC.

Jesus Christ dies on the cross

• c. 27: Jesus' baptism, start of ministry, and selection of the Apostles. The Gospel of Luke indicates that Christ was baptized during the 15th reign of Tiberius Caesar which is dated in 27 A.D (found in Luke 3:1,21,22). Christian Gospels strongly implicate Peter as leader and spokesman of the Apostles of Jesus being mentioned the most number of times in the Gospels. Peter, and the sons of Zebedee, James and John, constitute the inner circle of the Apostles of Jesus being witnesses to specific important events of the life of Jesus. Major preachings of Jesus, such as the Sermon on the Mount. Performance of miracles, such as raising the dead back to life, feeding five-thousand, walking on water, etc.
• c. 33: Peter declares and other followers believe Jesus of Nazareth to be the Jewish Messiah promised by Yahweh according to the Jewish Scriptures and the predictions of the Hebrew prophets. Entry into Jerusalem, start of Passion of Christ. Jesus of Nazareth is crucified in Jerusalem under Pontius Pilate, procurator of Judea during the reign of Tiberius and Herod Antipas, after the Sandhedrin, under the High Priest Caiaphas, accuse Jesus of blasphemy. He was crucified by the Romans, however, under the political crime of sedition and rebellion as the titulus on his cross indicated his crime clearly as: "Jesus of Nazareth, King of the Jews". According to his followers, three days later, "God raised him from the dead", or, as they also express it, he "has risen." Forty days after his resurrection (Ascension), the Christian Gospels narrate that Jesus instructed His disciples thus: "All authority has been given to me in heaven and on earth. Go therefore and make disciples of all the nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all things that I have commanded you; and lo, I am with you always, even to the end of time." (Matthew 28:18-20). Ten days later (Pentecost) Peter makes the first sermon converting 3,000 to be baptized. From this point onwards, the teachings of Jesus are spread throughout the Roman Empire and beyond forming into churches led by the Apostles. Christian tradition records that the Christian Church in Rome was jointly founded by Saint Peter and Saint Paul, and that Peter was its first bishop.
