An Evergreen Park priest has stepped aside from the ministry after the Archdiocese of Chicago received an accusation of sexual abuse of a minor from about 40 years ago.

In a letter Saturday, Cardinal Blase Cupich said someone reported that the abuse occurred when the Rev. Paul Guzman, an associate priest at Most Holy Redeemer Parish, was a layman, 25 years before he entered Mundelein Seminary to prepare for the priesthood.

The accusation was reported to the Illinois Department of Family and Child Services and the Cook County state’s attorney’s office while Guzman was overseas on military duty, Cupich said.

Guzman has agreed to live away from the parish during the investigation, Cupich said, and the accuser has been offered pastoral services of the archdiocese’s victim assistance ministry. An investigation by the archdiocese also is underway, according to Cupich.

Guzman could not be reached.

“It is important to remind everyone that, while the archdiocese takes every allegation of child sexual abuse seriously, the fact of an allegation does not presume guilt,” the cardinal wrote.

Last year, the Archdiocese of Chicago added dozens of names to an online list of priests credibly accused of sex abuse.
