The life of Jesus in the New Testament is primarily outlined in the four canonical gospels, which includes his genealogy and nativity, public ministry, passion, prophecy, resurrection and ascension. Other parts of the New Testament – such as the Pauline epistles which were likely written within 20 to 30 years of each other, and which include references to key episodes in Jesus' life, such as the Last Supper, and the Acts of the Apostles, (1:1–11) which includes more references to the Ascension episode than the canonical gospels - also expound upon the life of Jesus. In addition to these biblical texts, there are extra-biblical texts that Christians believe make reference to certain events in the life of Jesus, such as Josephus on Jesus and Tacitus on Christ.
