The second episode in a three-part series on the Second Vatican Council focuses on participation. In Luke 10, Christ himself says that Mary, who sits at his feet rather than help her sister, Martha, "chose the better part." Is she doing nothing? Or is she participating in Christ's mission in some way? At concerts and plays, we sit quietly, taking in the beauty of what we experience. Are we actively participating in those performances, and, if so, what does that mean for the Mass? Should we be more like Martha or Mary in the Liturgy?
