Speaking out for the first time Sept. 16 regarding the contents of a leaked document on church sexual abuse in Germany, Cardinal Marx attributed the abuse to the church "lacking attentiveness, lacking sensitivity, through the absence of love."

"God suffers about what we overlooked, where we looked away, what we did not want to believe as true," the cardinal said during his homily at a Mass in Schoenstatt, Germany.

The leaked document contained the findings of a confidential study, sponsored by the German bishops' conference, revealing that an estimated 3,700 minors were abused in Germany from 1946 to 2014. The bishops' conference did not disclose the findings to the public.

"The church experiences highs and lows," said Cardinal Marx. "Particularly in these days, we are thinking about the dark sides of what has happened and what is happening within the church."

The cardinal described it as shocking that children had experienced such suffering at the hands of priests they trusted.

"We stand on the side of the victims of sexual abuse. That is our continual duty," said Cardinal Marx. He said the bishops are "deeply depressed, shaken and ashamed before the reality of sexual abuse of minors within the Catholic Church."

During a Sept. 18 Mass in the Archdiocese of Munich and Freising to honor the vocation of priesthood, Cardinal Marx said it was "not easy" to discuss sexual abuse in the church. However, he said the bishops must "not avoid the challenge."

"We should take criticism as encouragement to grapple with this task," said Cardinal Marx. He said the German clergy should examine their consciences for signs of "carelessness" and "clerical posturing."

"Sin and violence are present throughout the history of the church," he said. "It is deeply disturbing that people within the church experience evil from people who are supposed to proclaim the Gospel."

The cardinal said the bishops' conference would examine the findings of the study during their upcoming plenary assembly in Fulda and discuss next steps.

"I am convinced that a great change is coming," said Cardinal Marx.
