A top Vatican cardinal says the Roman Catholic Church is more committed than ever to improving relations with Jews. Cardinal Walter Kasper told a conference of prelates and rabbis that after two-thousand years of antagonism, Catholics and Jews may still disagree -- but they do so as brothers. Fresh debate over the Vatican's position was sparked by an unofficial document published in August on the Web site of the U-S Conference of Catholic Bishops. It renounced "missionary efforts directed at converting Jews." The document, drafted by American Catholic and Jewish scholars, prompted a rebuttal by Cardinal Avery Dulles -- a top theologian. He said Catholics should try to convert everyone, including Jews, to faith in Jesus Christ.
