Do you wish to learn the secret of true Eucharistic prayer? Consider, then, all the mysteries in the light of the Blessed Sacrament. It is a divine prism through which they can all be studied. The Holy Eucharist is, indeed, 'Jesus Christ, yesterday, and today, and the same forever' (Heb 13:8). In this Sacrament He glorifies all the mysteries of His life and prolongs, as it were, the exercise of all His virtues. The Eucharist is, in a word, the great Mystery of our faith to which all Catholic truths lead.
