To these names others have subsequently been added. The requisite conditions are enumerated as three: eminens doctrina, insignis vitae sanctitas, Ecclesiae declaratio (i.e. eminent learning, a high degree of sanctity, and proclamation by the church). Benedict XIV explains the third as a declaration by the supreme pontiff or by a general council. But though general councils have acclaimed the writings of certain Doctors, no council has actually conferred the title of Doctor of the Church. The procedure involved extending to the Catholic Church the use of the Divine Office and Mass of the saint in which the title of doctor is applied to him.
