"And don't forget, converts are more committed than nonconverts," Egan said after delivering his homily on Sunday at St. Patrick's Cathedral.
Benedict is scheduled to arrive in Washington on Tuesday, his first visit as pope to the United States. He will meet with President Bush at the White House and the nation's bishops.
The pope then arrives in New York on Friday. His schedule also includes another Mass at St. Patrick's Cathedral, and a visit to Ground Zero.
