The Jesus Seminar is a group of about 150 individuals, including scholars with advanced degrees in biblical studies, religious studies or related fields as well as published authors who are notable in the field of religion, founded in 1985 by the late Robert Funk and John Dominic Crossan under the auspices of the Westar Institute. One of the most active groups in biblical criticism, the seminar uses votes with colored beads to decide their collective view of the historicity of Jesus, specifically what he may or may not have said and done as a historical figure. In addition, the seminar popularizes the quest for the historical Jesus. The public is welcome to attend the twice-yearly meetings. They produced new translations of the New Testament and apocrypha to use as textual sources. They published their results in three reports The Five Gospels (1993), The Acts of Jesus (1998), and The Gospel of Jesus (1999). They also run a series of lectures and workshops in various U.S. cities.

The seminar's reconstruction of the historical Jesus portrays him as an itinerant Hellenistic Jewish sage who did not die as a substitute for sinners nor rise from the dead, but preached a "social gospel" in startling parables and aphorisms. An iconoclast, Jesus broke with established Jewish theological dogmas and social conventions both in his teachings and behaviors, often by turning common-sense ideas upside down, confounding the expectations of his audience: He preached of "Heaven's imperial rule" (traditionally translated as "Kingdom of God") as being already present but unseen; he depicts God as a loving father; he fraternizes with outsiders and criticizes insiders.

The seminar treats the gospels as historical artifacts, representing not only some of Jesus' actual words and deeds but also the inventions and elaborations of the early Christian community and of the gospel authors. The fellows placed the burden of proof on those who advocate any passage's historicity. Unconcerned with canonical boundaries, they asserted that the Gospel of Thomas may have more authentic material than the Gospel of John.

While analyzing the gospels as fallible human creations is a standard historical-critical method, the seminar's premise that Jesus did not hold an apocalyptic world view is controversial. Rather than revealing an apocalyptic eschatology, which instructs his disciples to prepare for the end of the world, the fellows argue that the authentic words of Jesus indicate that he preached a sapiential eschatology, which encourages all of God's children to repair the world.
