Pre-existence of Christ in the context of "Logos (Christianity)"

Christology is a branch of Christian theology that concerns Jesus. Different denominations have different opinions on questions such as whether Jesus was human, divine, or both, and as a messiah what his role would be in the freeing of the Jewish people from foreign rulers or in the prophesied Kingdom of God, and in the salvation from what would otherwise be the consequences of sin.

The earliest Christian writings gave several titles to Jesus, such as Son of Man, Son of God, Messiah, and Kyrios, which were all derived from Hebrew scripture. These terms centered around two opposing themes, namely "Jesus as a preexistent figure who becomes human and then returns to God", versus adoptionism—the idea that Jesus was a human who was "adopted" by God at his baptism, crucifixion, or resurrection. Prior to 2007, the scholarly consensus was that the divinity of Christ was a later development, though most scholars now argue that a high Christology existed prior to Paul.

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).

In Christian theology, the incarnation is the belief that the pre-existent divine person of Jesus Christ, God the Son, the second person of the Trinity, who is also the Logos (Koine Greek for 'word'), was "made flesh" by being conceived through the power of the Holy Spirit in the womb of a woman, the Virgin Mary, who is also known as the Theotokos (Greek for "God-bearer" or "Mother of God"). The doctrine of the incarnation then entails that Jesus was at the same time both fully God and fully human.

In the incarnation, as traditionally defined by those Churches that adhere to the Council of Chalcedon, the divine nature of the Son was united but not mixed with human nature in one divine person, Jesus, or according to those adhering to the Council of Ephesus, the divine and human natures of Christ are fully united into one composite nature "without mixing, confusion, or separation". This is central to the traditional faith held by most Christians. Alternative views on the subject (see Ebionites and the Gospel of the Hebrews) have been proposed throughout the centuries, but all were rejected by Nicene Christianity.

The Gospel of the Hebrews (Koine Greek: τὸ καθ' Ἑβραίους εὐαγγέλιον, romanized: tò kath' Hebraíous euangélion), or Gospel according to the Hebrews, is a lost Jewish–Christian gospel. The text of the gospel is lost, with only fragments of it surviving as brief quotations by the early Church Fathers and in apocryphal writings. The fragments contain traditions of Jesus' pre-existence, incarnation, baptism, and probably of his temptation, along with some of his sayings. Distinctive features include a Christology characterized by the belief that the Holy Spirit is Jesus' Divine Mother and a first resurrection appearance to James, the brother of Jesus, showing high regard for James as the leader of the Jewish Christian church in Jerusalem. It was probably composed in Greek in the first decades of the 2nd century and is believed to have been used by Greek-speaking Jewish Christians in Egypt during that century.

The Gospel of the Hebrews is the only Jewish–Christian gospel that the Church Fathers referred to by name, believing there was only one Hebrew Gospel, perhaps in different versions. This has created confusion as modern scholars believe that the Church Fathers were, in reality, quoting three different gospels. All are known today only from fragments preserved in quotations by the early Church Fathers. Modern scholars have given these three different gospels the working name Gospel of the Hebrews, the Gospel of the Nazarenes, and the Gospel of the Ebionites.
