Catalina Rivas from México 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.
This link directs you to the text from her booklet, “The Holy Mass,” in which Our Lord and Our Lady explain to Catalina what is really going on during the Mass spiritually, while she is attending Mass. It is an interesting read.
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.”
