Paul VI was a man who lived a long time ago, in a place called Vatican City. People who believed in a religion called Catholicism thought he was a very important man because he was the leader of their religion.
Mass is a word that means how much something weighs. When we say we weigh 50 pounds, we are talking about our own mass.
But when people talk about the Mass of Paul VI, they are not talking about how much he weighed when he was alive. Instead, they are talking about a very special ceremony or event that people who believe in Catholicism do.
During this ceremony, a person called a priest stands in front of a crowd of people and says special prayers and hymns. They also pass around a special piece of bread and a special cup filled with wine. The bread and the wine are believed to be a special gift from a man named Jesus Christ, who lived a long time ago and is very important to people who believe in Catholicism.
The Mass of Paul VI is a specific kind of ceremony that was created by Paul VI when he was the leader of the Catholic Church. It includes special words and actions that are different from other kinds of Mass ceremonies that people do.
So, when people talk about the Mass of Paul VI, they are not talking about how much he weighed, but rather about a special ceremony in the Catholic religion that he created.
