God the Father in the context of "Theism"

In Christianity, Jesus is the Son of God as chronicled in the Bible's New Testament, as well as prophesied in the Old Testament, and is held to be God the Son, a prosopon (Person) of the Trinity of God. Christians believe him to be the Jewish messiah (giving him the title Christ), who was prophesied in the Bible's Old Testament. Through Jesus's crucifixion and resurrection, Christians believe that God offers humans salvation and eternal life, with Jesus's death atoning for all sin.

These teachings emphasize that as the Lamb of God, Jesus chose to suffer nailed to the cross at Calvary as a sign of his obedience to the will of God, as an "agent and servant of God". Jesus's choice positions him as a man of obedience, in contrast to Adam's disobedience. According to the New Testament, after God raised him from the dead, Jesus ascended to heaven to sit at the right hand of God the Father, with his followers awaiting his return to Earth and God's subsequent Last Judgement.

In Christianity, the Great Commission is the instruction of the resurrected Jesus Christ to his disciples to spread the gospel to all the nations of the world. The Great Commission is outlined in Matthew 28:16–20, where on a mountain in Galilee Jesus calls on his followers to make disciples of and baptize all nations in the name of the Father, the Son, and the Holy Spirit.

The Great Commission is similar to the episodes of the commissioning of the Twelve Apostles found in the other Synoptic Gospels, though with significant differences. Luke also has Jesus during his ministry dispatching disciples, including the seventy disciples, sending them to all the nations and giving them power over demons. The dispersion of the Apostles in the traditional ending of Mark is thought to be a 2nd-century summary based on Matthew and Luke.

In Christianity, the title Son of God refers to the status of Jesus as the divine son of God the Father.

It derives from several uses in the New Testament and early Christian theology. The terms "son of God" and "son of the LORD" are found in several passages of the Old Testament.

God the Son (Greek: Θεὸς ὁ Υἱός, Latin: Deus Filius) or God the Word (Greek: Θεὸς ὁ Λόγος, Latin: Deus Verbum) is the second Person of the Trinity in Christian theology. According to mainstream Christian doctrine, God the Son, in the form of Jesus Christ, is the incarnation of the eternal, pre-existent divine Logos (Koine Greek for "word") through whom all things were created. Although the precise term "God the Son" does not appear in the Bible, it serves as a theological designation expressing the understanding of Jesus as a part of the Trinity, distinct yet united in essence with God the Father and God the Holy Spirit (the first and third Persons of the Trinity respectively).

Faith in Christianity is often discussed in terms of believing God's promises, trusting in his faithfulness, and relying on God's character and faithfulness to act. Some denominations believe in the New Covenant and in the doctrine of salvation by faith alone (sola fide). According to most Christian traditions and denominations, Christian faith requires a belief in the resurrection of Jesus, and the Agony in the Garden which Jesus states is the plan of God the Father.

Since the Protestant Reformation of the 16th century, the meaning of the term faith has been an object of major theological disagreement in Western Christianity. The differences have been largely overcome in the Joint Declaration on the Doctrine of Justification (1999). The precise understanding of the term "faith" differs among the various Christian traditions. Despite these differences, Christians generally agree that faith in Jesus lies at the core of the Christian tradition, and that such faith is required in order to be a Christian.

The Holy Spirit, otherwise known as the Holy Ghost, is a concept within the Abrahamic religions. In Judaism, the Holy Spirit is understood as the divine quality or force of God manifesting in the world, particularly in acts of prophecy, creation and guidance. In Nicene Christianity, this conception expanded in meaning to represent the third person of the Trinity, co-equal and co-eternal with God the Father and God the Son. In Islam, the Holy Spirit acts as an agent of divine action or communication. In the Baha’i Faith, the Holy Spirit is seen as the intermediary between God and man and "the outpouring grace of God and the effulgent rays that emanate from His Manifestation".

The Trinity (Latin: Trinitas, lit. 'triad', from trinus 'threefold') is a Christian doctrine concerning the nature of God, which defines one God existing in three coeternal, consubstantial divine persons: God the Father, God the Son (Jesus Christ) and God the Holy Spirit, three distinct persons (hypostases) sharing one essence/substance/nature (homoousion).

The First Council of Nicaea (/naɪˈsiːə/ ny-SEE-ə; Ancient Greek: Σύνοδος τῆς Νικαίας, romanized: Sýnodos tês Nikaías) was a council of Christian bishops convened in the Bithynian city of Nicaea (now İznik, Turkey) by the Roman Emperor Constantine I. The Council of Nicaea met from May until the end of July 325.

This ecumenical council was the first of many efforts to attain consensus in the church through an assembly representing all Christendom. Hosius of Corduba may have presided over its deliberations. Attended by at least 200 bishops, its main accomplishments were the settlement of the Christological issue of the divine nature of God the Son and his relationship to God the Father, the construction of the first part of the Nicene Creed, the mandating of uniform observance of the date of Easter, and the promulgation of early canon law.

In Christianity, God is the eternal, supreme being who created and preserves all things. Christians believe in a monotheistic conception of God, which is both transcendent (wholly independent of, and removed from, the material universe) and immanent (involved in the material universe). Christians believe in a singular God that exists in a Trinity, which consists of three Persons: God the Father, God the Son, and God the Holy Spirit. Christian teachings on the transcendence, immanence, and involvement of God in the world and his love for humanity exclude the belief that God is of the same substance as the created universe (rejection of pantheism) but accept that God the Son assumed hypostatically united human nature, thus becoming man in a unique event known as "the Incarnation".

Early Christian views of God were expressed in the Pauline epistles and the early Christian creeds, which proclaimed one God and the divinity of Jesus. Although some early sects of Christianity, such as the Jewish-Christian Ebionites, protested against the deification of Jesus, the concept of Jesus being one with God was accepted by the majority of Gentile Christians. This formed one aspect of the split of early Christianity and Judaism, as Gentile Christian views of God began to diverge from the traditional Jewish teachings of the time.
