This Jesuit says that "discrimination against women within the Catholic community is so manifest" that the church "totters on the brink of compromising its self-identity as the basic sacrament of salvation."  

This isn't correct.  The all-male priesthood has been a part of the Church's self-identity for 2,000 years.  How can the Church be only now --- after 2,000 years --- be compromising its identity by maintaining part of its self-identity?  That self-identity may not be likable to some, but it IS the Church's self-identity.
