The Lifeblood of Christianity
“The importance of the passion and resurrection for the early church is evidenced by the relatively large amount of space the narrative takes in each of the Gospels and especially in Mark. "Out of Mark’s 661 verses, 128 are devoted to the passion and resurrection account, and a total of 242 are devoted to the last week (from the triumphal entry to the resurrection) of Jesus is life.
"The church obviously had more than a passing historical interest in Jesus’ death and resurrection. These events formed the basis of the church’s witness and worship—the lifeblood of early Christianity.”
