Why do bible have NIHIL OBSTAT and IMPRIMATUR?
“Nihil Obstat” is an official Roman Catholic Church approval, certifying that a work dealing with faith or morals has been reviewed by an appointed church theologian and does not contradict Catholic teaching. The “Censor Librorum” reviews the work as delegated by a bishop of the Roman Catholic Church. The Nihil Obstat is not a certification that the reviewer agrees with positions or approaches in the work. “Imprimatur” is official Roman Church approval that goes further and follows the “Nihil Obstat” certifying the work is free from error in matters of Roman Catholic doctrine and morals, and hence acceptable reading for Catholics. All this info is on wikipedia BTW.
