referred to as Lord in one case, and as Christ immediately thereafter. Master The Greek word Epistates (Epistata in the vocative case) is used only in Luke's gospel, where it occurs six times. Robert O'Toole argues that the word relates to Jesus' power over the material world rather than his teaching. Some commentators suggest that in Luke 5, Peter progresses from seeing Jesus as "Master" (v. 5) to seeing him as "Lord" (v. 8). Logos (the Word) John 1:1-18 calls Jesus the Logos (Greek ), often used as "the Word" in English translations. The identification of Jesus as the Logos which became Incarnate appears only at the beginning of the Gospel of John and the term Logos/Word is used only in two other Johannine passages: 1 John 1:1 and Revelation 19:13. It appears nowhere else in the New Testament. The series of statements regarding the Logos at the very beginning of the Gospel of John build on each other. The statement that the Logos existed "at the beginning" asserts that as Logos Jesus was an eternal being like God. The statement that the Logos was "with God" asserts the distinction of Jesus from God. The statement that the Logos "was God" states the unity of Jesus with God the Father, thus stating his divinity as God the Son. In 1 John 1:1 the arrival of the Logos as "the Word of life" from the beginning is emphasized and 1 John 5:6 builds on it to emphasize the water and blood of incarnation. With the use of the title Logos, Johannine Christology consciously affirms the belief in the divinity of Jesus: that he was God who came to be among men as the Word Incarnate. Although as of the 2nd century the use of the title Logos gave rise to debate between the Alexandrian and Antiochian schools of thought regarding the interaction of the human and divine elements in the Person of Christ, after the First Council of Nicaea in 325 and Council of Chalcedon in 451 the Logos and the second person of the Trinity were often used interchangeably. Son of God The title "Son of God" is applied to Jesus in many cases in the New Testament. It is often used to refer to his divinity, from the beginning in the Annunciation up to the Crucifixion. The declaration that Jesus is the Son of God is made by many
