Think Cardinal Newman has one more big step (canonization) to take? Think one more. Father Keith Beaumont, according to Zenit:
On this subject I received a confidence about which I cannot be explicit; but it seems that, in Newman’s case, his canonization and declaration as a doctor could take place in a very short time.
Regarding the Church’s list of doctors, would it surprise you to know that that saint-maker John Paul II only declared one doctor? That the aftermath of Vatican I saw as many new declarations (6) as the Tridentine century? That we’ve only had three declarations since Vatican II–all women? That the Anglicans have their own list?
Doctors are often depicted iconographically with books in hand.
