Query: Does Christianity come from Judaism?
Christianity emerged within Judaism, the key difference being the Christian belief that Jesus was the resurrected Messiah. Judaism is known to allow for multiple messiahs, the two most relevant being Messiah ben Joseph and the Messiah ben David. The idea of two messiahs — one suffering and the second fulfilling the traditional messianic role— was normal in ancient Judaism, and in fact predated Jesus.
Alan Segal has written that "one can speak of a 'twin birth' of two new Judaisms, both markedly different from the religious systems that preceded them. Not only were rabbinic Judaism and Christianity religious twins, but, like Jacob and Esau, the twin sons of Isaac and Rebecca, they fought in the womb, setting the stage for life after the womb."
The first Christians (the disciples or students of Jesus) were essentially all ethnically Jewish or Jewish proselytes. In other words, Jesus was Jewish, preached to the Jewish people and called from them his first disciples. Jewish Christians regarded "Christianity" as an affirmation of every aspect of contemporary Judaism, with the addition of one extra belief — that Jesus was the Messiah.
The doctrines of the apostles of Jesus brought the Early Church into conflict with some Jewish religious authorities (Acts records dispute over the resurrection of the dead, which was rejected by the Sadducees, see also Persecution of Christians in the New Testament), and possibly later led to Christians' expulsion from synagogues (see Council of Jamnia for other theories). 
While Marcionism rejected all Jewish influence on Christianity, Proto-orthodox Christianity instead retained some of the doctrines and practices of 1st-century Judaism while rejecting others, see the Historical background to the issue of Biblical law in Christianity and Early Christianity. They held the Jewish scriptures to be authoritative and sacred, employing mostly the Septuagint or Targum translations, and adding other texts as the New Testament canon developed. Christian baptism was another continuation of a Judaic practice.
In the 20th century, scholars became more likely to see early Christian faith and practice as evolving out of the religious beliefs and practices of Second Temple Judaism and Hellenic pagans, rather than standing out in sharp contrast to them. Modern historians have come to accept Jesus' Jewish identity and that of the apostolic church (referred to as Jewish Christianity). The relationship of Paul of Tarsus and Judaism is still disputed. The anti-Jewish Jesus of the gospels is now recognized as a later interpretation, perhaps Marcionite, as are the universalist themes in Acts and Luke. H. G. Wells, in his Outline of History, depicted Jesus as a man and Christianity as a religion of no divine distinction. Scholars such as Walter Bauer and Bart Ehrman have emphasized the diversity of early Christianity, with Proto-orthodox Christianity being one thread, against the traditional account of catholic unanimity.The historical and contextual time of the early church.
The next largest minority population is the Christian population (2%), many of whom live with Jewish communities. Rather than have their own education and medical institutions they have integrated into state institutions. The Christian population in Israel is the only Christian population in the Middle East that has grown in the last half century. Christians choose to live in Israel because they have freedom of speech and the freedom to practice religion.
In the first few centuries CE, there were many sects of Judaism (such as Pharisees, Essenes, and Sadducees) each claiming to be the correct faith. Some scholars treat Christianity, during that era, referred to as Early Christianity, as simply one of many sects of Judaism. Some sects wrote polemics advocating their position, and occasionally disparaging rival sects. Some scholars view the depictions of Jesus in the Talmud as a manifestation of those inter-sect rivalries – thus the depictions can be read as polemics by the rabbinic authors of the Talmud which indirectly criticized the rival sect (Christianity), which was growing and becoming more dominant.
According to Harvard University professor Robert D. Putnam, an increasing number of Americans are leaving their faith and becoming unaffiliated. By 2050, Christianity is expected to remain the majority in the United states (66.4%, down from 78.3% in 2010), and the number of Christians in absolute number is expected to grow from 243 million to 262 million.
According to a 2005 paper submitted to a meeting of the American Political Science Association, most of Christianity's growth has occurred in non-Western countries. The paper concludes that the Pentecostalism movement is the fastest-growing religion worldwide. Protestantism is growing as a result of historic missionary activity and indigenous Christian movements by Africans in Africa, and due primarily to conversion in Asia, Latin America, Muslim world, and Oceania. According to Pew Research Center, Christianity is declining in the United states while non-Christian faiths are growing.
The Christian population in Israel has increased significantly with the immigration of many mixed families from the former Soviet Union (1989-late 1990s) and by the influx of some 10,000 Christian Maronites from Lebanon in 2000. Recently a further increase in Christianity came with arrival of many foreign workers and asylum seekers, some of Christian background (for instance from the Philippines and South Sudan). As a result, numerous churches have opened in Tel Aviv.
Although analogies have been drawn between Buddhism and Christianity, there are differences between the two religions beginning with monotheism's place at the core of Christianity, and Buddhism's orientation towards non-theism (the lack of relevancy of the existence of a creator deity) which runs counter to teachings about God in Christianity; and extending to the importance of grace in Christianity against the rejection of interference with karma in Theravada Buddhism, etc. Another difference between the two traditions is the Christian belief in the centrality of the crucifixion of Jesus as a single event believed to act as the atonement of sins and its direct contrast to Buddhist teachings.
Around the 1st century CE, there were several small Jewish sects: the Pharisees, Sadducees, Zealots, Essenes, and Christians. After the destruction of the Second Temple in 70 CE, these sects vanished. Christianity survived, but by breaking with Judaism and becoming a separate religion; the Pharisees survived but in the form of Rabbinic Judaism (today, known simply as "Judaism"). The Sadducees rejected the divine inspiration of the Prophets and the Writings, relying only on the Torah as divinely inspired. Consequently, a number of other core tenets of the Pharisees' belief system (which became the basis for modern Judaism), were also dismissed by the Sadducees. (The Samaritans practiced a similar religion, which is traditionally considered separate from Judaism.)
Hundreds of years before the time of Jesus, Jewish prophets promised that a messiah would come. Judaism claims that Jesus did not fulfill these prophecies. Other skeptics usually claim that the prophecies are either vague or unfulfilled, or that the Old Testament writings influenced the composition of New Testament narratives. Christian apologists claim that Jesus fulfilled these prophecies, which they argue are nearly impossible to fulfill by chance. Many Christians anticipate the Second Coming of Jesus, when he will fulfill the rest of Messianic prophecy, such as the Last Judgment, the general resurrection, establishment of the Kingdom of God, and the Messianic Age (see the article on Preterism for contrasting Christian views).
Though some early Christians were aware of Buddhism which was practiced in both the Greek and Roman Empires in the pre-Christian period, the majority of modern Christian scholarship has roundly rejected any historical basis for the travels of Jesus to India or Tibet or direct influences between the teachings of Christianity in the West and Buddhism; and has seen the attempts at parallel symbolism as cases of parallelomania which exaggerate resemblances. However, in the East syncretism between Nestorian Christianity and Buddhism was widespread along the Silk Road in Antiquity and the Middle Ages, and was especially pronounced in the medieval Church of the East in China, as evidenced by the Jesus Sutras.
In contrast to the Jewish view of being morally balanced, Original Sin refers to the idea that the sin of Adam and Eve's disobedience (sin "at the origin") has passed on a spiritual heritage, so to speak. Christians teach that human beings inherit a corrupted or damaged human nature in which the tendency to do bad is greater than it would have been otherwise, so much so that human nature would not be capable now of participating in the afterlife with God. This is not a matter of being "guilty" of anything; each person is only personally guilty of their own actual sins. However, this understanding of original sin is what lies behind the Christian emphasis on the need for spiritual salvation from a spiritual Saviour, who can forgive and set aside sin even though humans are not inherently pure and worthy of such salvation. Paul the Apostle in Romans and I Corinthians placed special emphasis on this doctrine, and stressed that belief in Jesus would allow Christians to overcome death and attain salvation in the hereafter.
Christians ranked as the second most educated religious group around in the world with an average of 9.3 years of schooling. Christians were found to have the second highest number of graduate and post-graduate degrees per capita while in absolute numbers ranked in the first place (220 million). According to the study, Christians in North America, Europe, Middle East, North Africa and Asia-Pacific regions are highly educated since many of the world universities were built by the historic Christian churches, in addition to the historical evidence that "Christian monks built libraries and, in the days before printing presses, preserved important earlier writings produced in Latin, Greek and Arabic". According to the same study, Christians have a significant amount of gender equality in educational attainment, and the study suggests that one of the reasons is the encouragement of the Protestant Reformers in promoting the education of women, which led to the eradication of illiteracy among females in Protestant communities.
With the exception of a few Christian denominations, the Abrahamic religions originated before tobacco smoking was introduced to Europe from the New World. Therefore, these religions do not address it in their foundational teachings; however, modern practitioners have offered interpretations of their faith with regard to smoking.
In December 2009, 122,000 Arab Christians lived in Israel, as Arab citizens of Israel, out of a total of 151,700 Christian citizens. According to the Central Bureau of Statistics, on the eve of Christmas 2013, there were approximately 161,000 Christians in Israel, about 2 percent of the general population in Israel 80% of the Christians are of Arabic roots with smaller Christian communities of ethnic Russians, Greeks, Armenians, Maronites, Ukrainians and Assyrians. The majority of Arab Christians in Israel belong to the Greek Orthodox Church, with a sizable minority belonging to the Greek Catholic (Melkite) and Latin Churches. Other denominations are the Anglicans who have their cathedral church in the contested territory of East Jerusalem. Baptists in Israel are concentrated in the north of the country, and have four churches in the Nazareth area, and a seminary.
The first Christians in Rome were chiefly people who came from the East and spoke Greek. The founding of Constantinople naturally drew such people thither rather than to Rome, and then Christianity at Rome began to spread among the Roman population, so that at last the bulk of the Christian population in Rome spoke Latin. Hence the change in the language of the liturgy. ...The liturgy was said (in Latin) first in one church and then in more, until the Greek liturgy was driven out, and the clergy ceased to know Greek. About 415 or 420 we find a Pope saying he was unable to answer a letter from some Eastern bishops, because he had no one who could write Greek.
According to Christian Today, there were 2.4 billion Christians around the world in 2015. And according to a 2012 Pew Research Center survey, if current trends continue, Christianity will remain the world's largest religion by year 2050. By 2050, the Christian population is expected to exceed 3 billion. Many charismatic movements are growing in Africa, Latin America, Muslim world, and Asia.Other religions:
Early Christian art survives from dates near the origins of Christianity. The oldest surviving Christian paintings are from the site at Megiddo, dated to around the year 70, and the oldest Christian sculptures are from sarcophagi, dating to the beginning of the 2nd century. Until the adoption of Christianity by Constantine Christian art derived its style and much of its iconography from popular Roman art, but from this point grand Christian buildings built under imperial patronage brought a need for Christian versions of Roman elite and official art, of which mosaics in churches in Rome are the most prominent surviving examples.
With Christianity, historic Christian denominations such as the Catholic Church and Protestant Churches, including the Lutheran Church, recognize seven virtues, which correspond inversely to each of the seven deadly sins. 
Confession is the act of admitting the commission of a sin to a priest, who in turn will forgive the person in the name (in the person) of Christ, give a penance to (partially) make up for the offense, and advise the person on what he or she should do afterwards.
The US Department of State estimated in 2005 that Protestants in Vietnam may have grown by 600% over the previous 10 years. In South Korea, Christianity has grown from 2.0% in 1945 to 20.7% in 1985 and to 29.3% in 2010, And the Catholic Church has increased its membership by 70% in the last ten years. In Singapore, the percentage of Christians among Singaporeans increased from 12.7%, in 1990, to 17.5%, in 2010. In recent years, the number of Chinese Christians has increased significantly; Christians were 4 million before 1949 (3 million Catholics and 1 million Protestants), and are reaching 67 million today, Christianity is reportedly the fastest growing religion in China with average annual rate of 7%. Some reports also show that many of the Chinese Indonesians minority convert to Christianity, Demographer Aris Ananta reported in 2008 that "anecdotal evidence suggests that more Buddhist Chinese have become Christians as they increased their standards of education". According to a poll conducted by the Gallup Organization in 2006, Christianity has increased significantly in Japan, particularly among youth, and a high number of teens are becoming Christians. In Iran, Christianity is reportedly the fastest growing religion with an average annual rate of 5.2%.
There is no unilateral agreement among the different denominations of Judaism concerning truth. In Orthodox Judaism, truth is the revealed word of God, as found in the Hebrew Bible, and to a lesser extent, in the words of the sages of the Talmud. For Hasidic Jews truth is also found in the pronouncements of their rebbe, or spiritual leader, who is believed to possess divine inspiration. Kotzk, a Polish Hasidic sect, was known for their obsession with truth.
The Second Coming (sometimes called the Second Advent or the Parousia) is a Christian and Islamic belief regarding the future (or past) return of Jesus Christ after his ascension to heaven about two thousand years ago. The idea is based on messianic prophecies and is part of most Christian eschatologies.
There was a slowly growing chasm between Christians and Jews, rather than a sudden split. Even though it is commonly thought that Paul established a Gentile church, it took centuries for a complete break to manifest. However, certain events are perceived as pivotal in the growing rift between Judaism and Christianity. The Council of Jamnia c. 85 is often stated to have condemned all who claimed the Messiah had already come, and Christianity in particular. However, the formulated prayer in question (birkat ha-minim) is considered by other scholars to be unremarkable in the history of Jewish and Christian relations. There is a paucity of evidence for Jewish persecution of "heretics" in general, or Christians in particular, in the period between 70 and 135. It is probable that the condemnation of Jamnia included many groups, of which the Christians were but one, and did not necessarily mean excommunication. That some of the later church fathers only recommended against synagogue attendance makes it improbable that an anti-Christian prayer was a common part of the synagogue liturgy. Jewish Christians continued to worship in synagogues for centuries.
During the late 1st century, Judaism was a legal religion with the protection of Roman law, worked out in compromise with the Roman state over two centuries. Observant Jews had special rights, including the privilege of abstaining from civic pagan rites. Christians were initially identified with the Jewish religion by the Romans, but as they became more distinct, Christianity became a problem for Roman rulers. Emperor Nerva decreed that Christians did not have to pay the annual tax upon the Jews, effectively recognizing them as distinct from Rabbinic Judaism. This opened the way to Christians being persecuted for disobedience to the emperor as they continued to refuse to worship the state pantheon. It is notable that from c. 98 onwards a distinction between Christians and Jews in Roman literature becomes apparent. For example, Pliny the Younger postulates that Christians are not Jews since they do not pay the tax, in his letters to Trajan.
Talmudist and professor of Jewish studies Daniel Boyarin proposes a revised understanding of the interactions between nascent Christianity and Judaism in late antiquity, viewing the two "new" religions as intensely and complexly intertwined throughout this period. According to Boyarin, Judaism and Christianity "were part of one complex religious family, twins in a womb," for at least three centuries. Alan Segal also states that "one can speak of a 'twin birth' of two new Judaisms, both markedly different from the religious systems that preceded them."
Judaism does not believe that God requires the sacrifice of any human. This is emphasized in Jewish traditions concerning the story of the Akedah, the binding of Isaac. In the Jewish explanation, this is a story in the Torah whereby God wanted to test Abraham's faith and willingness, and Isaac was never going to be actually sacrificed. Thus, Judaism rejects the notion that anyone can or should die for anyone else's sin. Judaism is more focused on the practicalities of understanding how one may live a sacred life in the world according to God's will, rather than a hope of a future one. Judaism does not believe in the Christian concept of hell but does have a punishment stage in the afterlife (i.e. Gehenna, the New Testament word translated as hell) as well as a Heaven (Gan Eden), but the religion does not intend it as a focus.
Even as pagans and gentiles increasingly began to attend Christian worship, the Jewish framework remained strong. While the relationship of Paul the Apostle and Judaism is still debated, he initially took part in the reactive Jewish persecution of the early Christian movement, but following his conversion, he became a leading exponent for Christianity branching away from Judaism and becoming a religion open to all, which could move away from strict Jewish dietary laws and the requirement of circumcision. Judaism was recognized as a legal religion by Julius Caesar but the relationship was volatile resulting in several Jewish-Roman wars. Christianity did not receive legal recognition until the 313 Edict of Milan. The reign of the Emperor Constantine elevated Christianity to the preferred religion of the Roman State - while reducing the position of paganism and Judaism, with Christianity becoming the State church of the Roman Empire in 380. The dominance of Christianity was to flourish and outlast the Roman Empire.
