Text version of letter for those who have trouble reading the scanned copy:
Dear Bishop Robinson:
I am writing once again in reference to your planned speaking engagement in the Archdiocese of Los Angeles on June 12, 2008.
Your letter informing me of your coming appearance made it clear that you were not seeking my permission or approval, that you were planning to come regardless.
Since your communication, I have come to learn that your new book is being investigated by the Australian Bishops' Conference because of concerns about doctrinal errors and other statements in the book contrary to Church teaching.
I have also learned that His Eminence, Cardinal Giovanni Battista Re, the Prefect for the Congregation of Bishops, has urged you to cancel your visit to the United States.
Consequently, I am hereby requesting that you cancel your visit to the Archdiocese of Los Angeles now set for June 12, 2008. Canon 763 makes it clear that the Diocesan Bishop must safeguard the preaching of God's Word and the teachings of the Church in his own Diocese. Under the provisions of Canon 763, I hereby deny you permission to speak in the Archdiocese of Los Angeles.
As a brother Bishop, I would urge you to cancel the entire speaking tour and to work closely with your own Bishops' Conference on their investigations. I would surely expect you to follow exactly their recommendations in this matter.
With every best wish, I am
Sincerely yours in Christ,
Cardinal Roger M. Mahony
Archbishop of Los Angeles
