The newly formed Committee for Prevention of Sex Abuse by Clergy said today that in a news conference planned for Monday it will demand that the archdiocese conduct a new review of complaints dating back 40 years; turn over all such cases to law enforcement; and release abuse victims from orders of silence contained in legal settlements.

The group of 12 men, including several bankers and brokers from the wealthy North Shore suburbs, takes an orthodox approach to Catholicism. Many of its members have previously spoken out against liberalization of the sacraments and what they consider the church's overly tolerant view of homosexuality.

''I'm 100 percent for the church and its teachings,'' said one member of the group, George Morrow, a retired consultant and entrepreneur who lives on Chicago's Southwest Side. ''I'm against any abuses that go on in the church.''

The group's emergence came a day after Cardinal Francis E. George of Chicago was criticized by women's and victims' groups for drawing distinctions between serial pedophiles and priests who have sexual contact with teenagers.

Referring to John J. Geoghan, a former Boston priest accused of abusing nearly 200 boys over 30 years, Cardinal George said, ''There is a difference between a moral monster like Geoghan,'' who preys in serial fashion, and an individual who, ''perhaps under the influence of alcohol,'' engages in inappropriate behavior with ''a 16- or 17-year-old young woman who returns his affections.''

On television news programs Thursday night the local chapter of the National Organization for Women called for the cardinal's resignation. The chapter withdrew that demand today, after the cardinal clarified his statement, but said it would like to meet with him.

''What he said demonstrated that he does not have a complete understanding of the nature and harm of sexual abuse against children of all ages,'' NOW's Chicago vice president, Catherine Caporusso Hartman, said in an interview.

Cardinal George said he was sorry if his comments, made in Rome on Tuesday, were misunderstood. His statements had included the comment that such abuse ''is still a crime in every instance,'' and he reiterated that he considers both types of behavior ''a terrible crime.'' James Dwyer, the archdiocesan spokesman, said the cardinal's point was that a priest accused of a single encounter with a teenager is more likely to be rehabilitated than one who has preyed on dozens of small children.

''These are very complex issues and every situation has to be treated individually,'' Mr. Dwyer said. ''He certainly regrets that anybody would think that he would try to justify any kind of sexual abuse of minors of any age.''

The archdiocese has been seen as a model for how it handles sexual abuse cases since it set up a citizen's review board a decade ago. That policy has been copied nationwide.

Mr. Dwyer said the archdiocese's policy is to remove priests from parish work whenever an allegation of abuse is substantiated. In recent weeks, the Rev. Robert Kealy, a former chancellor of the archdiocese, resigned, and a retired priest, the Rev. Richard Fassbinder, was barred from any public ministry. Both developments stemmed from decades-old incidents.

But the new committee noted that Father Kealy had actually been involved in setting up the archdiocese's sexual abuse review board. Several committee members complained that the board has not supported victims.

The new group's leader, Michael Tario, an executive at Bank of New York who lives in Wilmette, a Chicago suburb, said his group does not want to get rid of Cardinal George. At a meeting earlier this month in Father Kealy's former parish, in Winnetka, another suburb, the cardinal asked for help in dealing with the sexual abuse scandals, Mr. Tario said. This committee is Mr. Tario's response.
