These "faithful Catholics" are waiting to "take possession of their Church" to tamper with the Sacraments, turning them from divine ordinances to mere man-made rituals.

If they have their way, what is to become of faithful Catholics, who fear the Lord and who would no more ordain women than they would baptize infants with isopropanol?  (We cannot be confident that it would be valid, the Church is not authorized to make that change.)  Shall we go down the same road as the Anglicans, splintering into sects and fighting in the secular courts over buildings?

Nobody is keeping women from "ministry", only Holy Orders, and even then because it is not certain that Holy Orders could be validly conferred on a woman.  Fear of the Lord.  Without Holy Orders we all share in the common priesthood and a woman called to minister should minister.

As for the cleric shortage what works is clear.  Look to Lincoln, for example.  Or OLMC in Carmel, Indiana.
