From Mark Allen Powell, Jesus as a Figure in History (Louisville, Ky: Westminster John Knox, 1998), 78:
"The group's [i.e. Jesus Seminar] ideological slant, then, may have been unintentional, but it is also undeniable. The Jesus Seminar is not representative of the guild of New Testament historical scholarship today. Rather, it is representative of one voice within that guild, a voice that actually espouses a minority position on some key issues. Nevertheless, this voice is a chorus. The charge "They all think alike!" is not completely accurate but, in any case, begs the question "Why do they think alike?" The harmony of so many usually independent voices is precisely what demands that attention be given to this chorus of scholars."
