Jeff Jacoby of the Boston Globe wrote an excellent column last week that does a very good job of describing Sabeel in light of their conference this weekend at the United Church of Christ "Old South Church" in Boston.
From the Boston Globe:
IN CIVILIZED circles it is considered boorish to speak of Jews as Christ-killers, or to use language evoking the venomous old teaching that Jews are forever cursed for the death of Jesus. Those circles apparently don't include the Sabeel Ecumenical Liberation Theology Center, an anti-Israel "peace" organization based in Jerusalem, or its founder, the Anglican cleric Naim Ateek.
Sabeel and Ateek are highly regarded on the hard-line Christian left, and regularly organize American conferences at which Israel is extravagantly denounced by numerous critics. So far this year, such conferences have been held in Cleveland, Berkeley, Calif., and Birmingham, Ala.; another begins Friday at Boston's Old South Church.
Just as critics of the United States are not necessarily anti-American bigots, critics of Israel are not necessarily biased against Jews. But Sabeel and Ateek's denunciations of Israel have included imagery explicitly linking the modern Jewish state to the terrible charge of deicide that for centuries fueled so much anti-Jewish hatred and bloodshed.
