"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)" (Online Catholic Encyclopedia).

"There are therefore now thirty-three Doctors of the Church, of whom eight are Eastern and twenty-four Western. They include three Carmelites, two Jesuits, three Dominicans, three Franciscans, a Redemptorist, and five Benedictines" (Online Catholic Encyclopedia, web editor's note).

Four traditional doctors of the West

"Certain ecclesiastical writers have received this title on account of the great advantage the whole Church has derived from their doctrine. In the Western church four eminent Fathers of the Church attained this honour in the early Middle Ages: St. Gregory the Great, St. Ambrose, St. Augustine, and St. Jerome. The 'four Doctors' became a commonplace among the Scholastics, and a decree of Boniface VIII (1298) ordering their feasts to be kept as doubles in the whole Church is contained in his sixth book of Decretals (cap. "Gloriosus", de relique. et vener. sanctorum, in Sexto, III, 22)" (Old Catholic Encyclopedia).

• St. Ambrose (340-397)
• St. Jerome (343-420)
• St. Augustine of Hippo (354-430; "The first doctor of the Church")
• Pope St. Gregory the Great (540-604)
