Voice of the Faithful, the lay group formed in response to the sexual abuse scandal in the Roman Catholic Church, is calling for the Vatican to review the requirement that priests be celibate, saying the policy may have played a role in the scandal. The position represents a shift in the approach of the organization, which has avoided raising such controversial issues. It comes as Voice of the Faithful faces a budget deficit from a drop-off in large donations and finds itself at a crossroads in direction.
