The first video is a beautiful description of the Holy Easter Mass. The second, is an explanation given at a retreat, which refers to the Mass in a more general fashion. The third has some crossover with the other two but was made specifically as an audio recording for anyone who does not have time to look at a video on the go.
As with all Sheen videos, all three are as compelling as they are enjoyable.
Fulton Sheen explains the traditional Mass
Fulton Sheen gives a talk on the nature of sacrifice in the Mass
A really wonderful piece of audio from Sheen discussing Christ's real presence in the Mass as well as the actions of the Priest
