<![CDATA[Pope Leo XIV will celebrate his inaugural mass on Sunday morning around 10 a.m. (that's 4 a.m. Eastern Time). Tens of thousands of people are expected to gather in St. Peter's Square for the "Holy Mass for the Beginning of the Pontificate." The pontiff will make an appearance for their sake before returning to St. Peter's Basilica to take part in the ceremony, which will include him receiving the Petrine Pallium and Fisherman's Ring, delivering a homily, and saying a prayer called the Regina Caeli. ]]>
