Wenski will start his job in the nine-county diocese Aug. 22. Officially, he has been appointed Orlando's coadjutor bishop, which means he will work with the 73-year-old Dorsey until the bishop retires. The Vatican requires all bishops to submit their resignations at age 75, but not all are immediately accepted."Then it's up to the Holy Father," Dorsey said. "I am tiring. I am getting older. I'm doing the best I can."Wenski has made his mark in Miami, and in the U.S. Conference of Catholic Bishops, as an advocate for the rights of immigrants and the poor. He also heads the Miami Archdiocese's Catholic Charities.
