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.
