"In this role as priest-secretary, it happened that during the conclave of June 1963, that which elected St. Pope Paul VI, Grech encountered the then-Cardinal Giovanni Battista Montini in the apostolic palace. Montini asked if he was the confessor of the conclave. Grech said he was not, but Montini asked if he could hear his confession nonetheless. A few hours later, Montini was elected pope.
In a 2013 interview, Grech recounted the story, saying that he hoped he did not give the future Pope Paul VI “too arduous a penance.”"
