John Henry Newman's decision to become a Roman Catholic was confirmed by his work on one of his major contributions to theology, Essay on the Development of Christian Doctrine . Ironically, the writings that brought him into the Catholic Church were viewed so suspiciously by Church officials that from his very first days as a Catholic he experienced distance, avoidance, distrust, and even cynicism in his relationship with the hierarchy.
