In Luke–Acts (two works from the same author) he then ascended into heaven, his rightful home. In the Gospel of John, Mary Magdalene found the tomb empty, and informed Peter. She then saw two angels, after which Jesus himself appeared to her. In the evening, Jesus appeared to the other followers, followed by another appearance a week later. He later appeared in Galilee to Peter, Thomas, and two other followers, commanding Peter to take care of his followers. In Acts of the Apostles, Jesus appeared to the apostles for forty days, and commanded them to stay in Jerusalem after which Jesus ascended to heaven, followed by the coming of the Holy Spirit at Pentecost, and the missionary task of the early church. In Christian theology, the death, resurrection, and exaltation of Jesus are the most important events, and a foundation of the Christian faith. The Nicene Creed states: "On the third day he rose again in accordance with the Scriptures". According to Terry Miethe, a Christian philosopher at Oxford University, the question " 'Did Jesus rise from the dead?' is the most important question regarding the claims of the Christian faith." According to John R. Rice, a Baptist evangelist, the resurrection of Jesus was part of the plan of salvation and redemption by atonement for man's sin. Summarizing its traditional analysis, the Catholic Church states in its Catechism:  For Christians, including some scholars, the resurrection is taken to have been a concrete, material resurrection. According to N. T. Wright in his book "The Resurrection of the Son of God", "There can be no question: Paul is a firm believer in bodily resurrection. He stands with his fellow Jews against the massed ranks of pagans; with his fellow Pharisees against other Jews." According to New Testament scholar Gary Habermas, "Many other scholars have spoken in support of a bodily notion of Jesus’ resurrection." According to Craig L. Blomberg, there are sufficient arguments for the historicity of the resurrection. Easter (or Easter Sunday) is the preeminent Christian feast that celebrates the resurrection of Jesus, and, according to Susan J. White, "is clearly the earliest Christian festival." According to Dunn, "In Easter we celebrate man become God [...] that in the death and resurrection of Christ God has broken the stranglehold of human selfishness, has proved the enduring and conquering strength of divine love." According to Thorwald Lorenzen, the first Easter led to a shift in emphasis from faith "in God" to faith "in Christ".
