The major Resurrection appearances of Jesus in the Canonical gospels (and to a lesser extent other books of the New Testament) are reported to have occurred after his death, burial and resurrection, but prior to his Ascension. Among these primary sources, most scholars believe First Corinthians was written first, authored by Paul of Tarsus along with Sosthenes c. AD 55. Finally, the Gospel of the Hebrews recounts the Resurrection appearance to James the brother of Jesus.
Paul lists several resurrection appearances of Jesus to various "men" but doesn't describe them. In Matthew, Jesus appears to Mary Magdalene and another Mary at his empty tomb. Later, the eleven disciples go to a mountain in Galilee to meet Jesus, who appears to them and commissions them to baptize in the name of the Father, Son, and Holy Spirit, and to make disciples of all people (the Great Commission).
