Between Moses and Elias Jesus shows forth His divine glory, thus foreshadowing His resurrection. He is the Alpha and the Omega, the beginning and the end of all things. Today’s Mass places before us the transfigured Lord and the model toward Whom we must tend, and our own transfiguration as the goal we must attain. We attain this goal by a profound realization of our sinfulness and need of a Redeemer; by preserving purity of body and soul; by combating our passions and carnal instincts and observing the commandments and most importantly by participating in the Mass. — Excerpted from Cathedral Daily Missal
