Cardinal Walter Kasper, president of the Pontifical Council for Promoting Christian Unity, warned that if the Church of England was to ordain women as bishops, as the Episcopal Church has done, then it could destroy any chance of reuniting the Anglican and Catholic Churches. Although ARCIC had completed a major document on Marian theology in 2003, John Paul II temporarily called off all future talks between the Catholic Church and the Anglican Communion after the consecration of Gene Robinson as bishop.
