"By its very nature the liturgy operates on different levels of communication which enable it to engage the whole human person. The simplicity of its gestures and the sobriety of its orderly sequence of signs communicate and inspire more than any contrived and inappropriate additions. Attentiveness and fidelity to the specific structure of the rite [...]
"This has always been the belief of the Church of God, that immediately after the consecration the true body and the true blood of our Lord, together with His soul and divinity exist under the form of bread and wine, the body under the form of bread and the blood under the form of wine." [...]

Do you seek Jesus Christ with the same desire, the same ardour, and nothing will hinder you from receiving Him. Long to communicate because there is nothing so great as the Eucharist. [...]
"St. John says that he saw our Lord girt up with a golden girdle, which supported His breasts: 'I saw the Son of Man girt about the paps with a golden girdle' (Apoc. i. 12, 13). Thus also is Jesus in the Sacrament of the Altar, with His breasts all filled with milk; that is [...]
"To accomplish so great a work, Christ is always present in His Church, especially in her liturgical celebrations. He is present in the sacrifice of the Mass, not only in the person of His minister, 'the same now offering, through the ministry of priests, who formerly offered himself on the cross', but especially under the [...]
