The lesson is an overview of the Sacraments. Find out where each Sacrament was instituted in Sacred Scripture and why both form (words) and matter (stuff) is necessary for the validity of each Sacrament. The lesson is taken from the Gospel of Saint Mark who tells us of a leper that is cleansed by Jesus. The dialogue between Jesus and the leper is a great example of how the Sacraments work in our life.
