Criterion of contextual credibility

The criterion of contextual credibility, also variously called the criterion of Semitisms and Palestinian background or the criterion of Semitic language phenomena and Palestinian environment is a tool used by Biblical scholars to help determine whether certain actions or sayings by Jesus in the New Testament are from the Historical Jesus. Simply put, if a tradition about Jesus does not fit the linguistic, cultural, historical, and social environment of Jewish Aramaic-speaking 1st-century Palestine, it is probably not authentic.
