St. Thomas — Apostle December 21

By nature slow to believe and somewhat inclined to look at the dark side of things, he had a most courageous and sympathetic heart. The words: “My Lord and my God,” to which the Church has attached an indulgence, were spoken by St. Thomas when, after a week of doubt as to the Resurrection of Jesus, he was convinced by the Lord Himself.

Because thou hast seen Me, Thomas, thou hast believed; blessed are they that have not seen, and have believed.

The Imitation of Christ
A wonderful thing it is, and worthy of faith, and transcending all human intelligence, that Thou, Lord God, true God and true man, art whole and entire under a small form of bread and wine, art eaten by the receiver and without being consumed.
Fifth Great Antiphon: Dawn of the East, Brightness of the Light Eternal, and Sun of Justice, come and enlighten them that sit in darkness and in the shadow of death.
Five days hence, and the sweet feast will be here. You have not forgotten that you were going to make some sacrifices for someone who could never find out who did it for them.
My Lord and my God!
