In the first chapter of his book Rise, Let Us Be on Our Way Pope John Paul II writes entertainingly of his early years in the Church. When he unexpectedly learns in 1958 that he has been named an auxiliary bishop the author, then a young priest, objects, "Your Eminence, I'm too young; I'm only thirty-eight."
The Primate replies, "That is a weakness which can soon be remedied."
