Some excerpts from Fr. Cantalamessa’s book, The Eucharist: Our Sanctification:
The Eucharist springs from love; the reason for every thing was that he loved us: ‘Christ love us and gave himself up for us, a fragrant offering and sacrifice to God’ (Eph 5:2).
At every ‘breaking of the bread’ when the priest breaks the host, it’s as if the alabaster vase of Christ’s humanity were being broken again, which is what happened on the Cross, and as if the perfume of his obedience were rising to touch the Father’s heart again.
“Drown yourself in the Blood of Christ crucified, bathe yourself in the Blood, inebriate and satiate yourself with the Blood and clothe yourself in the Blood. And if you are unfaithful, baptize yourself again in the Blood; if the devil has blurred your mind’s eye, cleanse your eyes with the Blood; if you become ungrateful for unseen gifts, be grateful in the Blood. . . . Melt your lukewarmness in the heat of the Blood and in the light of the Blood darkness will dissolve and you will be the spouse of Truth.” (Catherine of Siena, Letter 102)
And from St. Alphonsus Liguori:
If you are cold, do you think it sensible to move away from fire? Precisely because you feel your heart frozen you should go more frequently to Holy Communion, provided you feel a sincere desire to love Jesus Christ.
