The insistence on priestly celibacy is one of the major stumbling blocks to church unity. Discussions with the Orthodox church (which has always allowed married priests) and protestant denominations such as the Episcopal (Anglican) church often founder on the different conception of priesthood held by the Catholic church. Yet there is a precedent for allowing married priests - in the 1990s when British Anglican priests who could not accept women priests left the Church of England to become Catholics, they were allowed to serve as Catholic priests despite being married. Changing the rule more generally would make ecumenical dialogue more possible and open the way to the healing of historic schisms in the body of Christ.
