Sir, - Mr Murphy's Cathechism of Papal infallibility (December 30th) is most timely. Being a direct descendant of two Popes (Felix IV and Paul III) and a saint, I have often wondered why such an important and useful development has not passed down into my DNA. I note, however, that all my female relatives in the "Family of the Church" effortlessly assume their infallibility as a right! - Yours, etc.,
