Thus, under Pope Francis the somewhat unknown (at least in the Latin Church) St. Gregory of Narek was suddenly a Doctor of the Church, to go along with the better-known St. Irenaeus. Actually, every time his feast day rolls around, I’m amazed that he’s not already a Doctor of the Church. St. Ignatius of Loyola: like St. Francis of Assisi, supra, one of those supremely-far-sighted Saints who could see what the Church needed before the Church herself could envision it. The latter allowed the Church to expand through the efforts of great missionary Jesuit Saints such as St. Francis Xavier and St. Peter Canisius (another Doctor of the Church) the “second Apostle of Germany.” Almost unbelievably, there has not been a pope who was a Doctor of the Church since St. Gregory the Great (540-604)!
