Roman Catholic Archbishop Theodore McCarrick, of New Jersey, one of three U.S. religious leaders who have just returned from a high-level visit to China, is convinced that Christianity is spreading in the communist and officially atheist nation.

However, Archbishop McCarrick and others who took part in the visit to China have expressed concerns about religious rights and about limits to what the delegation was allowed to see.The China visit was made at the invitation of the Chinese president Jiang Zemin, who, during his first visit to Washington last October, found that allegations about religious rights in China were a major obstacle to improving U.S.-Chinese relations.
