After a week of headlines and dissent, Pope Francis delivered a sermon that -- once again -- offered silence as his strategic response to critics.

The "father of lies, the accuser, the devil" is trying to divide Catholics, said the pope. When faced with "people who do not have good will, with people who seek only scandal, who seek only division, who seek only destruction, even within families" the proper response is "silence, and prayer."

This echoed earlier remarks when, asked about a scathing epistle by the Vatican's former U.S. ambassador, Pope Francis said, "I will not say a single word on this."

Silence isn't what the authors of a "Letter to Pope Francis from Catholic Women" want to hear, right now. They want the pope to answer Archbishop Carlo Vigano's key accusations -- especially claims that Francis ignored evidence of sexual abuse against children and seminarians by ex-cardinal Theodore McCarrick of Washington, D.C.

"Our hearts are broken, our faith tested, by the escalating crisis engulfing our beloved Church," said the online petition, with more than 30,000 signatures at midweek. "The pain and suffering of the victims never ends, as each news cycle brings more horrific revelations of sexual abuse, sexual misconduct, cover-ups, and deceit -- even at the Church's highest levels."

Several of the Vigano's charges "require neither lengthy investigations nor physical evidence. They require only YOUR direct response, Holy Father."

Tensions have worsened in recent weeks, especially after a hellish grand-jury report about the crimes of 300 priests in six Pennsylvania dioceses. Then came news coverage validating decades of rumors about McCarrick, including testimony about his seduction and abuse of seminarians. Then came Vigano's blast, including charges that Francis trumped efforts by Pope Benedict XVI to push McCarrick out of the spotlight.

The women's statement was triggered by a "wave of problems that has produced so much anguish, confusion, dismay and anger," said Mary Rice Hasson, a Catholic scholar at the Ethics and Public Policy Center in Washington. "It's not like there has been one problem that we could solve with a few reforms. … The problems just keep coming at us, one after another."
