Timeline of the Catholic Church

As the oldest branch of Christianity, along with Eastern Orthodoxy,The Eastern Orthodox and some other churches are also apostolic in origin — i.e., they also date their origins back to the founding of the Church at the time of the Apostles the history of the Catholic Church plays an integral part of the History of Christianity as a whole. This article covers a period of just under 2,000 years.
Over time, schisms have disrupted the unity of Christianity. The major divisions occurred in c.144 with Marcionism,: "...they were perhaps the most dangerous foe Christianity has ever known." 318 with Arianism, in 1054 the East-West Schism of the Catholic Church with the Eastern Orthodox churches and in 1517 with the Protestant Reformation. 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, Western monasticism, the development of art, music, literature, architecture, the scientific method, and trial by jury. Also playing a role in world affairs including, 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 founding ==
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. The Gospels 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 (God the 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. He, however, aroused opposition from the Jewish religious leadership and authorities, see Rejection of Jesus. They saw his teachings as dangerous to traditional Jewish doctrine and practice, and felt that his hints about his own personal identity were blasphemous. According to the Gospel of Matthew, chapter 16, thus:
13 When Jesus went into the region of Caesarea Philippi, he asked his disciples, "Who do people say that the Son of Man is?"
14
 They replied, "Some say John the Baptist, others Elijah, still others Jeremiah or one of the prophets."
15
 He said to them, "But who do you say that I am?"
16
 Simon Peter said in reply, "You are the Messiah, the Son of the living God."
17
 Jesus said to him in reply, "Blessed are you, Simon son of Jonah. For flesh and blood has not revealed this to you, but my Father in Heaven.
18
 And so I say unto you, you are Peter, and upon this rock I will build my church, and the gates of Hell shall not prevail against it.
19
 And I will give you the keys of the kingdom of heaven. Whatever you bind on earth shall be bound in heaven; and whatever you loose on earth shall be loosed in heaven."
20
 Then he strictly ordered his disciples to tell no one that he was the Messiah.
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 was charged with blasphemy. During the trial by the Sanhedrin, he declared himself the Messiah. The Sanhedrin then 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 as recounted in the Gospels, tells of the events of Good Friday through 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.
Jesus had earlier stated that he would entrust to Simon Peter the keys of the Kingdom of Heaven after being singled out and revealed by God the Father that upon the "rock" (Latin Petrus, Greek Petros, and Aramaic Cepha) of Peter, Jesus would found his Church. Simon Peter was singled out again in the context of the Gospel of John, chapter 21 with the explicit verbal commands of "Feed my lambs", "Tend my sheep" and "Feed my sheep" in verses 15 to 17, thus:
 15
 When they had finished breakfast, Jesus said to Simon Peter, "Simon, son of John, do you love me more than these?" He said to him, "Yes, Lord, you know that I love you." He said to him, "Feed my lambs."
16
 He then said to him a second time, "Simon, son of John, do you love me?" He said to him, "Yes, Lord, you know that I love you." He said to him, "Tend my sheep."
17
 He said to him the third time, "Simon, son of John, do you love me?" Peter was distressed that he had said to him a third time, "Do you love me?" and he said to him, "Lord, you know everything; you know that I love you." Jesus said to him, "Feed my sheep."
It is on these foundational bases of scripture that the Catholic Church believes the Pope as the successor of Saint Peter and the singular leader of the whole Church on earth. The doctrines of Papal authority and Primacy of the Roman Pontiff continue to be reasons of division between the Catholic Church and other Christian groups, such as the Eastern Orthodox and Protestants.
== Up to 312 AD ==
* c. 4 BC: Nativity of Jesus. According to the Gospel of Luke, 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 the Divine Son of God incarnate or God the Son.

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.

* c. 195: Pope Victor I, first African Pope, excommunicated the Quartodecimans in an Easter controversy. Some think he may have been the first pope to celebrate Mass in Latin instead of Greek.This statement is made in derivative websites such as Cultural Catholic (retrieved 28 September 2006) and Catholic Apologetics International (retrieved 28 September 2006); but liturgical scholars are doubtful: early-twentieth-century Adrian Fortescue merely says, in two Catholic Encyclopedia articles, Liturgy of the Mass and Latin Church that, on the basis of the uncertain attribution to him of a work found among the writings of Saint Cyprian, Pope Victor seems to have been the first Pope "to use Latin at Rome" (referring to writing, not to liturgy); and the later Josef Jungmann makes no mention of this theory about Pope Victor, and states that the burial inscriptions of the Popes, which begin to be in Latin only with Pope Cornelius (d. 253), indicate that the change occurred later, while he observes that both languages will have been used in Rome for some centuries, according to the languages of the various groups of Christians in the city (page 65 of volume I of his Missarum Sollemnia - Eine genetische Erklärung der römischen Messe (Vienna, 1949) - the English translation, also in two volumes, is titled "The Mass of the Roman Rite: Its Origins and Development", and has been referred to as a "classic work", which "may be the best text on this most important mystery of our faith").

* October 28, 312: Emperor Constantine leads the forces of the Roman Empire to victory at the Battle of Milvian Bridge. Tradition has it that, the night before the battle, Constantine had a vision that he would achieve victory if he fought under the Symbol of Christ; accordingly, his soldiers bore on their shields the Chi-Rho sign composed of the first two letters of the Greek word for "Christ" (ΧΡΙΣΤΌΣ). After winning the battle, Constantine legalized Christianity. He himself was not baptized until shortly before death.

:It is our desire that all the various nations which are subject to our clemency and moderation, should continue the profession of that religion which was delivered to the Romans by the divine Apostle Peter, as it has been preserved by faithful tradition and which is now professed by the Pontiff Damasus and by Peter, Bishop of Alexandria, a man of apostolic holiness. According to the apostolic teaching and the doctrine of the Gospel, let us believe in the one Deity of the Father, Son and Holy Spirit, in equal majesty and in a holy Trinity. We authorize the followers of this law to assume the title Catholic Christians; but as for the others, since in our judgement they are foolish madmen, we decree that they shall be branded with the ignominious name of heretics, and shall not presume to give their conventicles the name of churches. They will suffer in the first place the chastisement of divine condemnation and the second punishment of our authority, in accordance with the will of heaven shall decide to inflict.
