CHICAGO (CBS) — The Archdiocese of Chicago announced Friday the consolidations of 19 parishes and schools into five “groupings” after crunching some numbers.

Starting next year, many of the parishes will combine into one or two churches depending on the needs of the communities.

Parishioners packed a tense meeting Friday night inside St. Thecla — one of the churches set to unite on Chicago’s northwest side in the “Milwaukee Avenue North” grouping. Parents and students worried about transitioning schools and some were upset about the plan.

“Objectively, any person that sat down and (looked) at this knows they made the wrong decision tonight,” said Luke Schutt, a graduate of St. Thecla.

Church leaders acknowledged the plan would be difficult for some.

“We need to rally our forces and concentrate our resources in one site and two sites will be left out of that, and I can understand entirely how that would be painful,” said Bishop Mark Bartosic.

As of July 1, St. Thecla and St. Cornelius will essentially move into nearby St. Tarcissus.
