Prior to the production of "The Flying Nun," producers were concerned with how the series would be received by Catholics. In an effort to prevent religious criticism, the National Catholic Office for Radio and Television (NCORT), served as a series adviser with on-screen credit. (The NCORT, like its motion-picture counterpart, the National Catholic Office for Motion Pictures, was ultimately absorbed into the United States Catholic Conference, and both were later merged into the Office for Film and Broadcasting of the United States Conference of Catholic Bishops, or USCCB.)
