St. John Henry Newman's Thoughts on the Importance of the Laity and Their Role in the Church?

In a recently posted article on St. John Henry Newman (See: [*St. John Henry Newman's Elevation as Doctor of the Church Seen as a Gift for Our Times*](https://www.ncregister.com/news/pentin-newman-doctor-providential)) , Fr. [Ignatius] Harrison who commented on five key teachings of the Saint only briefly addresses Newman's thoughts on the importance of the laity and their role in the Church: "that the laity is not supplementary' but crucial to the very foundation of the Church, and that he wanted an informed, and well-educated laity for the Church's mission.'" QUESTION: Can anyone expand in more detail St. John Henry Newman's teaching on the importance of the laity and their role in the Catholic Church? Primary references are appreciated. Thank you.
