Christians believe that Jesus, as the Messiah, was anointed by God as savior of humanity and hold that Jesus' coming was the fulfillment of messianic prophecies of the Old Testament. The Christian concept of the Messiah differs significantly from the contemporary Jewish concept.
The core Christian belief is that through belief in and acceptance of the death and resurrection of Jesus , sinful humans can be reconciled to God and thereby are offered salvation and the promise of eternal life. Jesus, having become fully human , suffered the pains and temptations of a mortal man, but did not sin. As fully God, he rose to life again. According to the New Testament , he rose from the dead,  ascended to heaven, is seated at the right hand of the Father  and will ultimately return [Acts 1: Little of Jesus' childhood is recorded in the canonical gospels, although infancy gospels were popular in antiquity.
In comparison, his adulthood, especially the week before his death, is well documented in the gospels contained within the New Testament , because that part of his life is believed to be most important. The biblical accounts of Jesus' ministry include: Jesus' death and resurrection are commemorated by Christians in all worship services, with special emphasis during Holy Week which includes Good Friday and Easter Sunday.
The death and resurrection of Jesus are usually considered the most important events in Christian theology , partly because they demonstrate that Jesus has power over life and death and therefore has the authority and power to give people eternal life.
Arguments over death and resurrection claims occur at many religious debates and interfaith dialogues. Salvation Christianity Paul the Apostle , like Jews and Roman pagans of his time, believed that sacrifice can bring about new kinship ties, purity and eternal life.
Gentiles who are "Christ's" are, like Israel, descendants of Abraham and "heirs according to the promise". According to both Catholic and Protestant doctrine, salvation comes by Jesus' substitutionary death and resurrection.
The Catholic Church teaches that salvation does not occur without faithfulness on the part of Christians; converts must live in accordance with principles of love and ordinarily must be baptized.
Christians differ in their views on the extent to which individuals' salvation is pre-ordained by God. Reformed theology places distinctive emphasis on grace by teaching that individuals are completely incapable of self-redemption , but that sanctifying grace is irresistible. Together, these three persons are sometimes called the Godhead ,    although there is no single term in use in Scripture to denote the unified Godhead.
Though distinct, the three persons cannot be divided from one another in being or in operation. While some Christians also believe that God appeared as the Father in the Old Testament , it is agreed that he appeared as the Son in the New Testament , and will still continue to manifest as the Holy Spirit in the present. But still, God still existed as three persons in each of these times. In some Early Christian sarcophagi the Logos is distinguished with a beard, "which allows him to appear ancient, even preexistent.
From earlier than the times of the Nicene Creed , , Christianity advocated  the triune mystery -nature of God as a normative profession of faith. According to Roger E. Olson and Christopher Hall, through prayer, meditation, study and practice, the Christian community concluded "that God must exist as both a unity and trinity", codifying this in ecumenical council at the end of the 4th century. The distinction lies in their relations, the Father being unbegotten; the Son being begotten of the Father; and the Holy Spirit proceeding from the Father and in Western Christian theology from the Son.
Regardless of this apparent difference, the three "persons" are each eternal and omnipotent. Other Christian religions including Unitarian Universalism , Jehovah's Witnesses , Mormonism and others do not share those views on the Trinity. The Latin word trias, from which trinity is derived, is first seen in the works of Theophilus of Antioch. Afterwards it appears in Tertullian. It is found in many passages of Origen. Trinitarianism Trinitarianism denotes those Christians who believe in the concept of the Trinity.
Almost all Christian denominations and churches hold Trinitarian beliefs. Since that time, Christian theologians have been careful to emphasize that Trinity does not imply that there are three gods the antitrinitarian heresy of Tritheism , nor that each hypostasis of the Trinity is one-third of an infinite God partialism , nor that the Son and the Holy Spirit are beings created by and subordinate to the Father Arianism.
Rather, the Trinity is defined as one God in three Persons. Nontrinitarianism Nontrinitarianism or antitrinitarianism refers to theology that rejects the doctrine of the Trinity. Various nontrinitarian views, such as adoptionism or modalism , existed in early Christianity, leading to the disputes about Christology. Christianity, like other religions, has adherents whose beliefs and biblical interpretations vary.
Christianity regards the biblical canon , the Old Testament and the New Testament , as the inspired word of God. The traditional view of inspiration is that God worked through human authors so that what they produced was what God wished to communicate. The Greek word referring to inspiration in 2 Timothy 3: Others claim inerrancy for the Bible in its original manuscripts, although none of those are extant.
Still others maintain that only a particular translation is inerrant, such as the King James Version. The books of the Bible accepted by the Orthodox, Catholic and Protestant churches vary somewhat, with Jews accepting only the Hebrew Bible as canonical; there is however substantial overlap. These variations are a reflection of the range of traditions , and of the councils that have convened on the subject. Every version of the Old Testament always includes the books of the Tanakh , the canon of the Hebrew Bible.
These books appear in the Septuagint , but are regarded by Protestants to be apocryphal. However, they are considered to be important historical documents which help to inform the understanding of words, grammar and syntax used in the historical period of their conception. Modern scholarship has raised many issues with the Bible.
Another issue is that several books are considered to be forgeries. The injunction that women "be silent and submissive" in 1 Timothy 2  is thought by many to be a forgery by a follower of Paul, a similar phrase in 1 Corinthians 14,  which is thought to be by Paul, appears in different places in different manuscripts and is thought to originally be a margin note by a copyist.
A final issue with the Bible is the way in which books were selected for inclusion in the New Testament. Other Gospels have now been recovered, such as those found near Nag Hammadi in , and while some of these texts are quite different from what Christians have been used to, it should be understood that some of this newly recovered Gospel material is quite possibly contemporaneous with, or even earlier than, the New Testament Gospels.
The core of the Gospel of Thomas , in particular, may date from as early as AD 50 although some major scholars contest this early dating ,  and if so would provide an insight into the earliest gospel texts that underlie the canonical Gospels, texts that are mentioned in Luke 1: The Gospel of Thomas contains much that is familiar from the canonical Gospels—verse , for example "The Father's Kingdom is spread out upon the earth, but people do not see it" ,  is reminiscent of Luke Scholarship, then, is currently exploring the relationship in the Early Church between mystical speculation and experience on the one hand and the search for church order on the other, by analyzing new-found texts, by subjecting canonical texts to further scrutiny, and by an examination of the passage of New Testament texts to canonical status.
Catholic interpretation Main article: Catholic theology of Scripture In antiquity, two schools of exegesis developed in Alexandria and Antioch. Alexandrine interpretation, exemplified by Origen , tended to read Scripture allegorically , while Antiochene interpretation adhered to the literal sense, holding that other meanings called theoria could only be accepted if based on the literal meaning. The spiritual sense is further subdivided into: The allegorical sense, which includes typology.
An example would be the parting of the Red Sea being understood as a "type" sign of baptism. The anagogical sense, which applies to eschatology , eternity and the consummation of the world Regarding exegesis , following the rules of sound interpretation, Catholic theology holds: The injunction that all other senses of sacred scripture are based on the literal   That the historicity of the Gospels must be absolutely and constantly held  That scripture must be read within the "living Tradition of the whole Church"  and That "the task of interpretation has been entrusted to the bishops in communion with the successor of Peter, the Bishop of Rome ".
Clarity of Scripture Protestant Christians believe that the Bible is a self-sufficient revelation, the final authority on all Christian doctrine, and revealed all truth necessary for salvation. This concept is known as sola scriptura. Martin Luther believed that without God's help Scripture would be "enveloped in darkness". The significance of the text includes the ensuing use of the text or application. The original passage is seen as having only a single meaning or sense.
The moment we neglect this principle we drift out upon a sea of uncertainty and conjecture. Taken together, both define the term Biblical hermeneutics.
