Magisterial Documents: Mysterium Fidei

Encyclical Letter on Eucharistic Doctrine and Worship Pope Paul VI
3 September 1965

The full document is available on the internet.

Brief History

Though Mysterium Fidei is not a Marian document, it is mentioned here because of its impact in the field of catechetics. Articles 52 and the pro forma conclusion are, on occasion, found in textbooks. Mysterium Fidei was quoted in the textbooks to stress the true human identity of Jesus Christ present in the Eucharist.
The doctrine taught on Mary is twofold:

1) St. Ambrose is quoted to give an example of miracles described in Scripture. These include "Christ's birth of the Virgin Mary." (MF 51) The Berengarius' oath, which professes belief in Christ's presence in the Eucharist, is quoted in full. The Marian text states "after the consecration, there is present the true body of Christ which was born of the Virgin." (MF 52)

2) In the conclusion, in addition to linking Mary with the Eucharist, Mary's intercession is asked: "May the Most Blessed Virgin Mary from whom Christ our Lord took the flesh which under the species of bread and wine "is contained, offered and consumed, (CIC, 1917, Can. 801) ... intercede before the Father of mercies [Christ] so that from this same faith in, and devotion toward, the Eucharist may result and flourish a perfect unity of communion among all Christians." (MF 75)
