Doctors of the Church
Catholic Christians believe that the promise of the Spirit of Truth to guide believers in truth is found in the constant faith of the Church as preserved in the writings of the Doctors of the Church also, equally "faithful people." The Doctors of the Church are eminent Christian teachers who are proclaimed to be worthy of the title. The Church recognized these faithful people and teachers for their contribution to the belief and understanding of the faith. Doctors of the Church must be canonized a saint, known for their learning, and must be proclaimed such by either the Bishop of Rome or an ecumenical council.
