I was a little disappointed the first time I stepped into Henry Koch's 1870 Calvary Presbyterian Church - that soaring red building on 10th and Wisconsin. The sanctuary has been completed remodeled and modernized. The pews are gone, replaced by stacks of movable chairs. The wooden chancel isn't ornately adorned as one might expect in a 150-year-old church, and the new hardwood floors gleam rather than creak with accumulated history. But, then, Pastor Mark McDonough converted me.
