In order to analyze biblical passages, Käsemann introduced the criterion of dissimilarity, that compares a gospel passage (e.g. a statement by Jesus) to the Jewish context of the time, and if dissimilar, places weight on its being on safe ground. During the second quest the criterion of embarrassment was also introduced. This criterion states that a group is unlikely to invent a story that would be embarrassing to themselves. For instance, this criterion argues that the early Christian Church would have never wanted to invent the kernel of the story about the Baptism of Jesus because John baptised for the remission of sins, and Jesus was viewed as without sin, hence the story served no purpose, and would have been an embarrassment given that it positioned John above Jesus. While the baptism of Jesus itself may be a historical event, the presence of the dove and the voice from Heaven may be later embellishments to the original happening. Marcello Craveri's "Life of Jesus" in 1967, based on the Dead Sea Scrolls, argued that the claims to divinity made by the historical Jesus were strictly limited and not unusual for a Jew of that generation. Much of the stronger claims, and the emphasis on the redeeming power of Christ's death on the Cross, could be seen as reworkings by St. Paul, who was probably influenced strongly by the Graeco-Roman traditions.
