VATICAN CITY (AP) — Cardinals from around the world delved head-on Thursday into one of the most vexing issues facing the church, how to find ways to provide better pastoral care for divorced and remarried Catholics who are forbidden from receiving Communion and other church sacraments.

German Cardinal Walter Kasper, a pre-eminent theologian who has called for “openings and changes” in dealing with these Catholics, delivered a two-hour keynote speech to the two-day meeting, which is serving as preparation for an October summit of bishops on family issues.
