You can explain to Mr. McShane that the Holy See considers that Your Excellency's ruling in the case of "Call to action Nebraska" was properly taken within your competence as Pastor of that diocese. The judgement of the Holy See is that the activities of "Call to Action" in the course of these years are in contrast with the Catholic Faith due to views and positions held which are unacceptable from a doctrinal and disciplinary standpoint. Thus to be a member of this Association or to support it, is irreconcilable with a coherent living of the Catholic Faith."

The March 22 decree of Lincoln, Nebraska Bishop Fabian Bruskewitz threatening
excommunication of CTA members has caused a bonanza of national publicity, new members and increased donations for CTA. It has also strengthened the fledgling CTA Nebraska, which drew 75 people to its first meeting Feb. 3, and 200 at its second event Apr. 27.
The saga began when Bruskewitz reacted to the establishment of CTA Nebraska
by proclaiming that anyone among the 85,000 Catholics in his diocese who belongs to CTA or CTA Nebraska after May 15 faces automatic excommunication. He also banned membership in ten other organizations, including Planned Parenthood, Catholics for a Free Choice, and Masonic groups, but CTA was clearly his reason for acting now.

(National level) CTA: 25 years of Spirituality and Justice
O Mary conceived without sin, pray for us who have recourse to thee!
Don't forget the Hour of Grace:
With Prayers and Penance. Pray the 51st Psalm with outstretched arms three
times. During the Hour of Grace, many spiritual graces will be granted. The most
hard-hearted sinners will be touched by the grace of God.The Blessed Virgin promised that whatever a person asked Her for during this Hour of Grace (even in
impossible cases) would be granted to them, if it was in accordance with the
Will of the Eternal Father.
