I tried to come up with a definition before I watched the video. I started thinking about the seven sacraments and how God gives us his grace through them. That led me to The Last Supper and the Institution of The Holy Eucharist where Jesus taught his apostles how to say the Mass. Of course, Peter, The Rock, Jesus was going to build his church through St. Peter. Well, since I had to get back to work, I decided to watch the video.

Of course, that makes perfect sense. Wish I would have thought of that first. How would you define "Catholicism"?
