Put your sins in the chalice for the precious blood to wash away. One drop is capable of washing away the sins of the world.
The Eucharist is connected with the Passion. If Jesus had not established the Eucharist we would have forgotten the crucifixion. It would have faded into the past and we would have forgotten that Jesus loved us. There is a saying that to be far away from the eyes is to be far away from the heart. To make sure that we do not forget, Jesus gave us the Eucharist as a memorial of His love.
—Blessed Teresa of Calcutta (Mother Teresa)
If then Death was the supreme moment for which Christ lived, it was therefore the one thing He wished to have remembered. He did not ask that men should write down His Words into a Scripture; He did not ask that His kindness to the poor should be recorded in history; but He did ask that men remember His Death. And in order that its memory might not be any haphazard narrative on the part of men, He Himself instituted the precise way it should be recalled.
—Abp Fulton Sheen, Calvary and the Mass
