Much as I wish I could encourage the discontented, the Catholics of open minds and open hearts, to stay put and fight the good fight, this is a lost cause... Summon your fortitude, and just go. If you are not getting the spiritual sustenance you need, if you are uneasy being part of an institution out of step with your conscience -- then go. The restive nuns who are planning a field trip to Rome for a bit of dialogue? Be assured, unless you plan to grovel, no one will be listening. Sisters, just go.
Do I worry that in some way I represent "an institution out of step with" my "conscience"? Absolutely. I worry often about "representing" a church whose man-made laws (doctrine) increase the suffering of the poor, the powerlessness of women, and causes deaths in developing regions.
We know through painful experience that freedom is never voluntarily given by the oppressor; it must be demanded by the oppressed.
