Jewish Christianity in the context of "Second Temple Judaism"

Western culture, also known as Western civilization, European civilization, Occidental culture, Western society, or simply the West, is the internally diverse culture of the Western world. The term "Western" encompasses the social norms, ethical values, traditional customs, belief systems, political systems, artifacts and technologies primarily rooted in European and Mediterranean histories. A broad concept, "Western culture" does not relate to a region with fixed members or geographical confines. It generally refers to the classical era cultures of Ancient Greece, Ancient Rome, and their Christian successors that expanded across the Mediterranean basin and Europe, and later circulated around the world predominantly through colonization and globalization.

Historically, scholars have closely associated the idea of Western culture with the classical era of Greco-Roman antiquity. However, scholars also acknowledge that other cultures, like Ancient Egypt, the Phoenician city-states, and several Near-Eastern cultures stimulated and influenced it. The Hellenistic period also promoted syncretism, blending Greek, Roman, and Jewish cultures. Major advances in literature, engineering, and science shaped the Hellenistic Jewish culture from which the earliest Christians and the Greek New Testament emerged. The eventual Christianization of Europe in late-antiquity would ensure that Christianity, particularly the Catholic Church, remained a dominant force in Western culture for many centuries to follow.

The Gospel of Matthew is the first book of the New Testament of the Bible and one of the three synoptic Gospels. It tells the story of who the author believes is Israel's messiah (Christ), Jesus, his resurrection, and his mission to the world. The Gospel of Matthew presents Jesus as the fulfillment of Jewish prophecy.

Matthew wishes to emphasize that the Jewish tradition should not be lost in a church that was increasingly becoming gentile. The gospel reflects the struggles and conflicts between Jewish Christians and the other Jews, particularly with its sharp criticism of the scribes, chief priests and Pharisees, presenting the view that the Kingdom of Heaven has been taken away from them and given instead to the church. It emphasizes Jesus’s role as the Son of David, Son of Man, and Son of God, and frames his teachings, miracles, and parables to reflect both Jewish law and the emerging Christian church. Structured around alternating narratives and discourses—including the Sermon on the Mount, parables, and instructions for discipleship—it culminates in the Passion, Resurrection, and the Great Commission.

Early Christians were heavily persecuted throughout the Roman Empire until the 3rd century. Although Christianity initially emerged as a small Jewish movement in 1st-century Judaea, it quickly branched off as a separate religion and began spreading across the various Roman territories at a pace that put it at odds with the well-established Roman imperial cult, to which it stood in opposition; Christians were vocal in their expressions of abhorrence towards the beliefs and practices of Roman paganism, such as deifying and making ritual sacrifices to the Roman emperor or partaking in other methods of idolatry. Consequently, the Roman state and other members of civic society routinely punished Christians for treason, various rumoured crimes, illegal assembly, and for introducing an alien cult that drove many Roman people to apostasy in favour of Jesus Christ. According to Tacitus, the first wave of organized persecution occurred under Nero (r. 54–68), who blamed Christians for the Great Fire of Rome in 64. A number of mostly localized persecutions occurred during the reign of Marcus Aurelius (r. 161–180). After a lull, persecution resumed under Decius (r. 249–251) and Trebonianus Gallus (r. 251–253). The Decian persecution was particularly extensive, as Decius strived to restore the Roman golden age in part by forcing pagan practices upon the Christian community. Another wave of persecution began under Valerian (r. 253–260), but ceased abruptly after he was captured and taken prisoner by the Sasanian Empire during the Battle of Edessa of the Roman–Persian Wars. Under his successor Gallienus (r. 253–268), whose reign was marred by rapidly escalating military conflicts of the Crisis of the Third Century, the first ever decree of tolerance was issued for Christian practices and places of worship, although it stopped short of recognizing Christianity as a religion with legal status.

Emperor Diocletian (r. 283–305) began the Diocletianic persecution, which was the final and the most severe wave of persecution of Christians by the Roman state. It was enforced until the accession of Galerius (r. 305–311), who issued the Edict of Serdica, and the death of Maximinus Daza (r. 310–313). After Constantine the Great (r. 306–337) defeated his rival Maxentius (r. 306–312) at the Battle of the Milvian Bridge in October 312, he and his co-emperor Licinius issued the Edict of Milan, which decriminalized Christianity and suppressed pagan populations throughout the Roman Empire. In 380, Theodosius I (r. 379–395) issued the Edict of Thessalonica, officially establishing Christianity as the Roman state religion. It was also during the reign of Theodosius I that pagan practices were overtly deemed punishable offenses, which laid the framework for early Byzantine anti-pagan policies.

Christianity in the ante-Nicene period was the period in Christian history following the Apostolic Age (1st century AD) up to the First Council of Nicaea (325 AD). Although the use of the term Christian (Koine Greek: Χριστιανός) is attested in the Acts of the Apostles (80–90 AD), the earliest recorded use of the term Christianity (Koine Greek: Χριστιανισμός) is attested by the ante-Nicene Father and theologian Ignatius of Antioch (c. 107 AD).

While the Jewish–Christian community was centered in Jerusalem in the 1st century AD, Gentile Christianity spread widely in the 2nd century AD. One stream of Gentile Christianity (so-called "proto-Orthodox Christianity") that emerged in this period in the persons and theological positions of the Apostolic Fathers would eventually become the international Great Church. Proto-Orthodox Christianity placed importance on the sacrifice of Jesus on the cross as saving humanity, and described Jesus as the incarnated Son of God come to Earth. The 2nd and 3rd centuries AD saw a sharp separation between Jewish Christianity and Gentile Christianity, with the latter being derived from the teachings of the Apostle Paul. There was an explicit rejection of Second Temple Judaism and Jewish culture by the end of the 2nd century, with a growing body of anti-Jewish Christian literature. Many doctrinal variations in this era defy neat categorizations, as various forms of Christianity interacted in a complex fashion.

The Hebrews (Hebrew: עִבְרִיִּים / עִבְרִים, Modern: ʿĪvrīm / ʿĪvrīyyīm, Tiberian: ʿĪḇrīm / ʿĪḇrīyyīm; ISO 259-3: ʕibrim / ʕibriyim) were an ancient Semitic-speaking people. Historians mostly consider the Hebrews as synonymous with the Israelites, with the term "Hebrew" denoting an Israelite from the nomadic era, which preceded the establishment of the Kingdom of Israel and Judah in the 11th century BCE. However, in some instances, the designation "Hebrew" may also be used historically in a wider sense, referring to the Phoenicians or other ancient Semitic-speaking civilizations, such as the Shasu on the eve of the Late Bronze Age collapse. It appears 34 times within 32 verses of the Hebrew Bible. Some scholars regard "Hebrews" as an ethnonym, while others do not, and others still hold that the multiple modern connotations of ethnicity may not all map well onto the sociology of ancient Near Eastern groups.

By the time of the Roman Empire, the term Hebraios (Greek: Ἑβραῖος) could refer to any member of the Jewish people in general (as Strong's Hebrew Dictionary puts it: "any of the Jewish nation") or, at other times, specifically to those Jews who lived in Judea, which was a Roman province from 6 CE to 135 CE. However, at the time of early Christianity, the term instead referred to Jewish Christians, as opposed to the Judaizers and to the gentile Christians.

Two names and a variety of titles are used to refer to Jesus in the New Testament. In Christianity, the two names Jesus and Emmanuel that refer to Jesus in the New Testament have salvific attributes. After the crucifixion of Jesus the early Church did not simply repeat his messages, but focused on him, proclaimed him, and tried to understand and explain his message. One element of the process of understanding and proclaiming Jesus was the attribution of titles to him. Some of the titles that were gradually used in the early Church and then appeared in the New Testament were adopted from the Jewish context of the age, while others were selected to refer to, and underscore the message, mission and teachings of Jesus. In time, some of these titles gathered Christological significance.

Christians have attached theological significance to the Holy Name of Jesus. The use of the name of Jesus in petitions is stressed in John 16:23 when Jesus states: "If you ask the Father anything in my name he will give it you." There is widespread belief among Christians that the name Jesus is not merely a sequence of identifying symbols but includes intrinsic divine power.

Ebionites (Ancient Greek: Ἐβιωναῖοι, romanized: Ebiōnaîoi, derived from Hebrew language אֶבְיוֹנִים, ʾEḇyōnīm, meaning 'the poor' or 'poor ones') as a term refers to a nontrinitarian Mosaic Law-observant Jewish-Christian sect that existed in Palestine and Transjordan during the early centuries of the Common Era.

Since historical records by the Ebionites are scarce, fragmentary and disputed, much of what is known or conjectured about them derives from the polemics of their Gentile-Christian opponents, specifically the Church Fathers—Irenaeus, Origen, Eusebius, and Epiphanius of Salamis—who saw the Ebionites as an unorthodox sect more or less distinct from other Jewish-Christian sects, such as the Nazarenes.

Gnosticism (from Ancient Greek γνωστικός (gnōstikós) 'having knowledge'; Koine Greek: [ɣnostiˈkos]) is a collection of religious and philosophical ideas and systems that coalesced in the late first century AD among sects of early Christianity and other faiths. It is not a singular, homogeneous tradition or religion, but an umbrella term used by modern scholars to describe different groups and beliefs that shared certain characteristics. These diverse Gnostic groups generally emphasized personal spiritual knowledge (gnosis) above the authority, traditions, and proto-orthodox teachings of organized religious institutions. The Gnostic worldview typically distinguished between a hidden, uncorrupted supreme being and a flawed demiurge responsible for creating material reality. Gnostics held this material existence to be evil and believed the principal element of salvation was direct knowledge of the supreme divinity, attained via mystical or esoteric insight. Many Gnostic texts deal not in concepts of sin and repentance, but with illusion and enlightenment.

Although the exact origins of Gnosticism cannot be traced, Gnostic writings flourished among certain Christian groups in the Mediterranean during the second century. In the Gnostic Christian tradition, Christ was seen as a divine being that had taken human form in order to lead humanity back to recognition of its own divine nature. Judean–Israelite Gnosticism, including the Mandaeans and Elkesaites, blended Jewish-Christian ideas with Gnostic beliefs focused on baptism and the cosmic struggle between light and darkness. Syriac–Egyptian groups like Sethianism and Valentinianism combined Platonic philosophy and Christian themes, seeing the material world as flawed but not wholly evil. Other traditions include the Basilideans, Marcionites, and Thomasines. Manichaeism, which adopted Gnostic concepts such as cosmic dualism, emerged as a major religious movement in the third century, briefly rivaling Christianity.
