Why can’t a woman represent the “unique headship of Jesus Christ”?
Christ’s role as head of the Church and bridegroom are fundamentally male, for whatever reason in the mystery of God. The fatherhood of the clergy has a deeply symbolic relation to the maternal function of the Church. In one sense, Christ leads the Church; in another sense, Christ comes to wed the Church. The dynamic is this: Christ the head, caring for his Church; Christ the groom, married to his bride, the Church.
