As the leaders of the 28 NATO countries arrive in Chicago for a summit meeting May 20-21, several Catholic institutions are making plans to keep their parishioners, students and other users on track. Part of the issue is that there has been relatively little information on what to expect during the summit or in the days leading up to it. The U.S. Coast Guard has issued notice that waterways including large sections of the lakefront and the Chicago River could be closed to boat traffic between May 16-24. As world leaders come to Chicago, or travel through the city, roads could be closed, and protestors could also cause blockages and delays. At Holy Name Cathedral, the expected ordination of 14 new priests was moved from the usual ordination date of the third Saturday in May — this year May 19 — to the week before, according to Msgr. Dan Mayall, the pastor of Holy Name Cathedral. That move was made when Chicago was still expecting to host the G-8 summit in the days leading up to the NATO summit. The G-8 was later moved to Camp David. De La Salle Institute — both the boys’ Institute Campus and the girls’ Lourdes Hall campus — changed their graduation dates at the cathedral to avoid the summits as well, Mayall said. DePaul University and Loyola University, which both have campuses in the downtown area, are working with federal and local officials to make their plans, but so far, are unsure of how much effect the summit will have on their operations. St. Ignatius College Prep has a “flexible plan, so it will be there in case we need it,” said Catherine Karl, the school’s principal. The plan calls on teachers to continue their students’ education away from school for a short period of time, whether by giving them long-term assignments they can work on independently or offering podcasts or other distance- learning opportunities. “We know where we want to be at the end of May, so we’ve asked the faculty how we can get there if for some reason we don’t have school at school,” Karl said. While the school, at 1076 W. Roosevelt Road, will likely be out of the way of street closures, students come from seven counties and the school needs to be sure they and the faculty can get to and from school safely. St. Ignatius has joined many Catholic high schools in moving proms away from the dates of the summit or away from downtown.
