"The Apostles were the nucleus of the new ecclesia or body. Through them and their successors, Christ would still continue to teach, govern and sanctify. Up until the day of Pentecost, they were like chemicals in a laboratory. We know up to 100 percent the chemicals which enter into the constitution of a human body, but we cannot make one, because we cannot create the vivifying, unifying principle - the soul." Archbishop Fulton Sheen
