St. Peter’s isn’t a “parish” type parish. People who “belong” to St. Peter’s are encouraged to also register and support their “regular” parish.
St. Peter’s offers a Catholic presence in Chicago’s Loop. A lot of Chicagoans are Catholic; always has been. The majority of the people who work in the Loop take public transportation, often an hour or a little longer one way from the suburbs. And working 10 hours is not unusual. It’s hard to get home in time for Mass on a holy day, or to go to confession. So, St. Peter’s fills the bill.
You’ll seldom see a wedding or funeral at St. Peter’s, and it’s almost an impossibility to see infant baptism, children’s First Communion or Confirmation. It’s because no children’s formation is offered, and permission of the couple’s individual pastors is needed for a wedding (or in the case of the dead, better have a better reason than location).
The classes St. Peter’s offers are geared to adults who work in the Loop. The other ministries give business people a chance to help out the homeless who end up in the Loop, something that Chicago does not address well (It’s an all-or-nothing thing, Chicago’s answers, and doesn’t always help). The friars are really good about that one. They offer 2 12-step groups. There is a lot of young adult ministry.
THAT SAID-
Some of the educational offerings are through the Catholic Theological Union.
ctu.edu/About_Us/Our_Story/It was the birthing room of a lot of liberal thought in this country, and some of the less than conservative ideas and practices that seeped into the Mass and Catholic thought.
Some of the friars participate in 8th Day Center for Justice and other groups that are less conservative.
Will you find pseudo-ordained women? No. Is it St. John Cantius? No.
