Robert Funk died in 2005, Marcus Borg in 2015, Stephen L. Harris in 2019, but notable surviving fellows of the Jesus Seminar include John Dominic Crossan, Robert M. Price and Burton Mack. Borg was a liberal Christian who articulated the vision hypothesis to explain Jesus' resurrection. Some view Crossan as an important voice in contemporary historical Jesus research, promoting the idea of a non-apocalyptic Jesus who preaches a sapiential eschatology. Funk was a well-known scholar of recent American research into Jesus' parables. Harris is the author of several books on religion, including university-level textbooks. Mack describes Jesus as a Galilean Cynic, based on the elements of the Q document that he considers to be earliest.
