The resurrection of Jesus () is the Christian belief that God raised Jesus on the third day after his crucifixion, starting – or restoring – his exalted life as Christ and Lord. According to the New Testament writing, Jesus was firstborn from the dead, ushering in the Kingdom of God. He appeared to his disciples, calling the apostles to the Great Commission of forgiving sin and baptizing repenters, and ascended to Heaven. For the Christian tradition, the bodily resurrection was the restoration to life of a transformed body powered by spirit, as described by Paul and the Gospel authors, that led to the establishment of Christianity. In Christian theology, the resurrection of Jesus is "the central mystery of the Christian faith". It provides the foundation for that faith, as commemorated by Easter, along with Jesus's life, death and sayings.

One of the letters sent by Paul the Apostle to one of the early Greek churches, the First Epistle to the Corinthians, contains one of the earliest Christian creeds referring to post-mortem appearances of Jesus, and expressing the belief that he was raised from the dead, namely 1 Corinthians 15:3–8. It is widely accepted that this creed predates Paul and the writing of First Corinthians. Scholars have contended that in his presentation of the resurrection, Paul refers to this as an earlier authoritative tradition, transmitted in a rabbinic style, that he received and has passed on to the church at Corinth. Geza Vermes writes that the creed is "a tradition he [Paul] has inherited from his seniors in
