Urbi et Orbi ('to the
city [of Rome] and to the
world') denotes a papal address and
apostolic blessing given by the
pope on certain solemn occasions, usually only Christmas and Easter.
An indulgence is a Grace from God given to us through the Church to heal our souls or others from the consequences of sin here on earth or after death. Participating in this prayer with the Pope will grant us an indulgence if we have the intention to come to Confession and Receive the Eucharist as soon as we can go back to Church. Please watch the video below for an deeper explanation of what an indulgence is.
