Latin Doctores Ecclesiae

For those of you who sit and ask thyself, "I wonder who the Doctors of the Latin Church are" look no further.

"(Latin Doctores Ecclesiae) -- 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)."
