The Holy Liturgy Explained to Catalina by Jesus and Mary Catalina Rivas of Cochabamba, Bolivia, who now dwells in Mérida, Yucatán, México. She is said to receive Messages from Jesus, Mary, and the angels. She has the approval of her Bishop, René Fernández Apaza, who has given his imprimatur to her Messages. The following text is the reproduction of booklet, “The Holy Mass,” in which Our Lord and Our Lady explain to Catalina what is really going on during the Mass in the spiritual realm, and how we should be more concentrated on the great mysteries that are taking place.  Bo. Daniel Gagnon, OMI, of the Commission for the Doctrine of the Faith of the Archdiocese of Mexico, wrote about this book: “I do not find anything against the faith or the customs of the Church. It is not my function to confirm its supernatural character; nevertheless, I recommend it for its spiritual inspiration.”  The testimony of Catalina on the Holy Mass  In a marvelous catechesis, the Lord and the Virgin Mary have been instructing us first on how to pray the Rosary, that being to pray it with our hearts, and meditate and enjoy the moments when we encounter God and our Blessed Mother. They have also instructed us on the way to make a good confession and, in this document, a teaching on what happens during the Holy Mass and how to live it with our hearts. This is the testimony that I must and want to give to the whole world, for the greater Glory of God and for the salvation of all of those who want to open their hearts to the Lord. It is also given so that many souls consecrated to God will rekindle the fire of their love for Christ, some of whom are the owners of the hands that have the power to bring Him to our world so that He can become our nourishment. It is also given for others so that they break loose of the “routine practice” of receiving Him, and relive the amazement of their daily encounter with Love. And it is given so that my lay brothers and sisters from the entire world live the greatest Miracle with their hearts: the celebration of the Holy Eucharist.  Download testimony in English Download testimony in Dutch
