The Pope gave the pallium to the new archbishop of Milan, Angelo Cardinal Scola earlier today. The pallium is a symbol of communion between the wearer (normally metropolitan archbishops) the pope. Hence, it is more ecclesial in nature than liturgical, though the pallium is rarely worn outside of the celebration of the Mass. He can give it whenever and to whomever he wants. Custom of recent years is that the pope gives the pallium to those metropolitans who request it on the feast of Saints Peter and Paul. Nevertheless, this is a novel event that indicates a personal relationship between the cardinal and the pope.
Today is the 20th anniversary of episcopal ordination of Cardinal Scola and he's due to be installed as the new archbishop of Milan on the 25th, moving from being the Patriarch of Venice.
