In 1901, the application of criteria of authenticity began with dissimilarity. It was often applied unevenly with a preconceived goal. The criterion of dissimilarity or discontinuity says that if a particular saying can be plausibly accounted for as the words or teaching of some other source contemporary to Jesus, it is not thought to be genuine evidence of the historical Jesus. The "Son of Man" sayings are an example. Judaism had a Son of Man concept (as indicated by texts like and ), but there is no record of the Jews ever applying it to Jesus. The Son of Man is Jesus' most common self-designation in the Gospels, yet none of the New Testament epistles use this expression, nor is there any evidence that the disciples or the early church did. The conclusion is that, by the process of elimination of all other options, it is likely historically accurate that Jesus used this designation for himself.
