True god

In 1 John 5:20, Jesus is the True God. "...We are in union with the one who is true, his Son Jesus the Messiah, who is the true God and eternal life."
In Matthew 1:20-23 (NASB), an angel told Joseph: "20...Joseph, son of David, do not be afraid to take Mary as your wife; for the Child who has been conceived in her is of the Holy Spirit. 21 “She will bear a Son; and you shall call His name Jesus, for He will save His people from their sins.” 22 Now all this took place to fulfill what was spoken by the Lord through the prophet: 23 “BEHOLD, THE VIRGIN SHALL BE WITH CHILD AND SHALL BEAR A SON, AND THEY SHALL CALL HIS NAME IMMANUEL,” “GOD WITH US.”
In the Gospel of Matthew, Jesus's genealogy (Matthew 1:2–16) uses the title "Anointed One" ("Christ") for Jesus, in the sense of an anointed king. It lists the succession of the anointed kings of Judah, starting with David through Solomon until Jeconiah. All of them belong to the Davidic Dynasty, which terminated when Babylon conquered Judah. Then the successors listed after Jeconiah are heirs for when a Neo-Davidic Dynasty is finally restored to Judah. At the conclusion of the list, Jesus is then identified as a new king and thus called the "Anointed One".
John Dominic Crossan says that the titles "Divine", "Son of God", "God", "Lord", "Redeemer", "Liberator", and "Saviour of the World" were collectively applied to Octavian, who became Caesar Augustus after defeating Mark Antony at the Battle of Actium in 31 B.C. Crossan cites what he calls the adoption of them by the early Christians to apply to Jesus as denying them of Caesar the Augustus. "They were taking the identity of the Roman emperor and giving it to a Jewish peasant. Either that was a peculiar joke and a very low lampoon, or it was what the Romans called majistas and we call high treason. In 42 BC, Julius Caesar was formally deified as "the divine Julius" (divus Iulius). His adopted son, Octavian (better known by the title "Augustus" given to him 15 years later, in 27 BC)[thus became known as "divi Iuli filius" (son of the divine Julius)[or simply "divi filius" (son of the used this title to advance his political position, finally overcoming all rivals for power within the Roman stateThe title was for him "a useful propaganda tool", and was displayed on the coins that he issuedThe word applied to Julius Caesar as deified is "divus", not the distinct word "deusThus Augustus was called "Divi filius", but never "Dei filius", the expression applied to Jesus in the Vulgate translation of the New Testament, as, for instance, in 1 John 5:5, and in earlier Latin translations, as shown by the Vetus Latina text "Inicium evangelii Ihesu Christi filii dei" preserved in the Codex Gigas. As son of Julius Caesar, Augustus was seen as the son of a god, not as the son of God, which was how the monotheistic Christians saw Jesus.
