Brooklyn Auxiliary Bishop Witold Mroziewski, a native of Poland, is going to World Youth Day (WYD) with 400 pilgrims from Brooklyn and Queens, as well as Bishop Nicholas DiMarzio and Auxiliary Bishop Octavio Cisneros. The bishop sees a deep connection between the Year of Mercy proclaimed by Pope Francis and celebrating World Youth Day in Krakow, a city rich in history in the southern part of Poland.
